Early years

Horgan began his senior club hurling career with Passage West in 1966.

Horgan began his club hurling career with Passage West, however, after a largely unsuccessful juvenile and underage career he transferred to Blackrock in 1968.

Horgan was just 21-years-old when he was chosen by his peers to captain the Blackrock senior team for the 1971 championship campaign. It was a successful campaign which led to the Rockies qualifying for their first county final in eight years. St. Finbarr's were the opponents and took a strong 2-0 to 0-2 lead after just eight minutes. A torrential downpour before the game made conditions very difficult and tempers boiled over with Simon Murphy and Charlie Cullinane being sent to the line. Blackrock fought back and a Ray Cummins goal in the 24th minute helped to level matters at the interval. Charlie McCarthy completed his hat-trick to give St. Finbarr's the lead early in the second half, however, Blackrock's youth and fitness were key in securing a 2-19 to 5-4 victory. Not only was it Horgan's first championship medal but he also had the honour of collecting the Seán Óg Murphy Cup as captain. Due to the unsporting manner of the contest the Cork County Board later fined the two teams a combined total of £30 and suspended five players, including Horgan, for a period of two months. This suspension had little impact on Blackrock's subsequent Munster Championship campaign, with Horgan being reinstated by the time his side faced Moyne-Templetuohy in the provincial decider. An impressive 4–10 to 3–1 victory gave him his first Munster medal. Blackrock subsequently qualified for an All-Ireland final meeting with rathnure on 14 May 1972. The Leinster champions were in arrears by twelve points at one stage, however, they launched a stunning comeback to cut the deficit down to one point. Blackrock stubbornly held on to secure a 5-13 to 6-9 victory. Not only was Horgan's first All-Ireland medal but he also had the honour of receiving the cup as captain.

National dominance

Blackrock surrendered their county, provincial and national titles the following year, however, they qualified for the county final once again in 1973. Reigning champions Glen Rovers provided the opposition and, after dominating the first half, held a 1-8 to 0-6 interval lead. Horgan had an outstanding second half and scored a trademark point from a 70-yards free. Blackrock held a point lead from the 55th minute and survived two Glen Rovers raids before securing a 2-12 to 2-10 victory. It was Horgan's second county championship medal. Newmarket-on-Fergus were the opponents as Blackrock reached another Munster final. There were never more than a few points between the teams throughout the match, with Newmarket spurning a goal chance just before the interval. Blackrock held out for a narrow 1-13 to 0-14 victory and Horgan collected a second winners' medal. The All-Ireland final on 17 March 1974 saw Blackrock and Rathnure renew their rivalry once again. Dan Quigley netted the first goal for Rathnure, however, Éamonn O'Donoghue secured Blackrock's first goal seconds later when he kicked the sliotar over the goal-line. Half-time saw the sides retire having scored 1-7 apiece. Donie Collins put Blackrock ahead early in the second half, however, Quigley soon scored his second to restore parity. A ten-minute period of dominance by Blackrock yielded only three points, while Quigley completed his hat-trick with a goal from a 21-yards free to give Rathnure a one-point lead. Pat Moylan secured the equaliser. The replay on 28 April 1974 produced a tension-charged climax as Blackrock turned almost certain defeat into victory. The first half saw a number of unsavoury incidents, with John O'Halloran (Blackrock) and Mick Mooney (Rathnure) becoming the first players ever to be sent off in an All-Ireland club final. As the game entered stoppage time, Rathnure held a one-point lead. Blackrock's Donie Collins sent in a ground shot which goalkeeper Michael Foley let slip through his legs. Éamonn O'Donoghue secured the victory with a goal in the second minute of injury time. The 3-8 to 1-9 victory gave Horgan a second All-Ireland medal as captain.

Once again back-to-back championship titles eluded the Rockies, however, they qualified for the county final in 1975. The game against Glen Rovers was expected to be an exciting affair, however, the expectation was not fulfilled. The half-back line of Frank Cummins, Horgan and Dermot McCurtain closed down the Glen attack and contributed greatly to the 4-11 to 0-10 victory. It was Horgan's third winners' medal at county level. The subsequent provincial decider saw Mount Sion provided the opposition, however, Blackrock were in impressive form. Horgan was the star at centre-back before having to retire late in the game with an injury. Ray Cummuns scored 3-3 as Blackrock powered to an 8-12 to 3-8 victory and a third Munster medal for Horgan. Blackrock entered the All-Ireland final on 14 March 1976 and got off to a great start as Éamonn O'Donoghue scored a goal inside the first minute. A goal from a Pat Moylan penalty in the 16th minute gave Blackrock a lead of 2-1 with James Stephens yet to score. The Village then made a vital switch as Joe Hennessy was moved from right wing-forward to right wing-back. By half time James Stephens had cut the lead to five points as they trailed by 2-2 to 0-3. James Stephens were transformed in the second half with their full-back and half-back lines repelling the Blackrock attack. A draw looked likely as the game entered the final stage, however, a last minute Mick Leahy goal put the game beyond doubt as James Stephens claimed a 2-10 to 2-4 victory.

After defeat at the hands of Glen Rovers in 1976, it took Blackrock two years before they qualified for their next county final. Glen Rovers were the opponents once again, with the game remaining on an even keel for 40 minutes. Blackrock took over for the last period, winning the game by 4-12 to 1-7. It was Horgan's fourth championship medal and his third as captain of the team. Once again the Rockies stormed through the provincial championship and defeated Newmarket-on-Fergus by 3-8 to 1-8 in the decider, giving Horgan a fourth Munster medal. On 25 March 1979, Blackrock faced Ballyhale Shamrocks in the All-Ireland final. The first half was completely dominated by Horgan's side who opened the scoring with a goal from a 21-yards free by Pat Moylan in the first minute. Two further goals by Ray Cummins in the 17th and 18th minutes put Blackrock ahead by 3-2 to 0-2. A third goal by Éamonn O'Sullivan helped them to reach half-time in the comfortable position of being 12 points ahead. Blackrock appeared to have the game wrapped up when Tom Lyons whipped through a goal to leave them 14 points ahead with just a quarter of an hour left to play. Ger Fennelly pointed a free to reduce the deficit for Ballyhale, before Pat Holden, Kevin Fennelly and Liam Fennelly scored three goals without reply. Moylan pointed to reinforce the lead for Blackrock, however, a long shot from out the field landed in the Blackrock square before Brendan Fennelly got the final touch to send it over the line. The referee originally signalled a free to Blackrock, however, after consulting with his umpires he awarded the goal. This left the Shamrocks trailing by two points, however, they failed to score in the remaining time as the Rockies won by 5-7 to 5-5. For the third time in his career Horgan had captained his club to the All-Ireland title.

Decline

Blackrock qualified for their seventh county championship decider of the decade in 1979. St. Finbarr's provided the opposition in what was the sides' first final meeting since 1971. The Barr's took a one-point lead in the 20th minute after John Allen struck for a goal. Blackrock responded with a 1-1 from Frank Cummins and Tom Lyons. St. Finbarr's missed two gilt-edged goal opportunities in the second half, as Blackrock claimed a 2-14 to 2-6 victory. It was Horgan's fifth winners' medal in the championship. After missing Blackrock's 0-13 to 1-8 Munster final triumph over Dunhill, Horgan was returned to the team for the subsequent All-Ireland semi-final. Castlegar of Galway shocked the reigning champions with a 2-9 to 0-9 defeat.

Early success

Horgan made his senior debut for Cork on 12 October 1969 in a 1-15 to 1-3 defeat of Wexford in the semi-final of the Grounds Tournament. He became a regular starter throughout the subsequent league before making his championship debut in a 4-13 to 3-6 Munster semi-final defeat of Limerick. This victory qualified Cork for a Munster final meeting with Tipperary, in what was the first 80-minute provincial decider. Leading by eight points early in the second half, Tipperary had to play the majority of the match with fourteen men after Liam King was dismissed in the opening half. Cork laboured in attack, however, two goals from Willie Walsh and a third from Charlie Cullinane secured a narrow 3-10 to 3-8 victory. It was Horgan's first Munster medal. Cork subsequently qualified to play Wexford in the All-Ireland final on 6 September 1970. Horgan, at left corner-back, came in for praise with the other members of the full-back line - Tony Maher and Pat McDonnell - in quelling the Wexford attack. A record 64-point scoreline and eleven goals were produced in a sometimes ill-tempered and disappointing contest. Tony Doran top scored for Wexford with two goals, however, the day belonged to Eddie O'Brien who scored a hat-trick of goals for Cork from his hand. A remarkable 6–21 to 5–10 score line gave Cork the victory and gave Horgan his first All-Ireland medal.^[14] A week after the All-Ireland victory, Cork travelled to the United States where they faced New York in the league final. Cork won the two-leg series of game on an aggregate score of 5-21 to 6-16, with Horgan adding a National Hurling League medal to his collection.

Team exclusion

As Cork began their defence of their championship titles in 1971, Horgan was moved to centre-back for Cork's opening game. He scored two points from that position, however, Limerick were the winners by 2-16 to 2-14.

After falling out of favour with the Cork selectors in early 1972, Horgan was dropped from the team. He was added to the list of substitutes for the drawn Munster final with Tipperary before being dropped from the panel for all subsequent games. He was returned to the team for a league game against Clare in the opening rounds of the 1972-73 season, before regaining his place on Cork's championship starting fifteen.

Horgan was appointed captain of the Cork team in 1974 and was at his customary position of left corner-back for Cork's league final meeting with Limerick. An Éamonn O'Donoghue hat-trick was one of the highlights for Cork, who routed their opponents by 6-15 to 1-12. It was Horgan's second league medal. A disappointing championship campaign followed for Cork, with Horgan being dropped from the panel once again after a loss of form. It was during his time off the team that Horgan collected his first All-Star award, a move which saw his return to the Cork panel.

After a return to form, Horgan was included on Cork's championship panel in 1975. Cork qualified for the Munster final, however, Horgan, after an impressive display against Clare in the semi-final, started the match on the bench. He was introduced as a substitute and collected a second Munster medal as Cork defeated Limerick by 3-14 to 0-12.

Three-in-a-row

In 1976 Horgan was restored to Cork's starting fifteen where he occupied the centre-back position. Cork qualified for the Munster final once again, however, he had a tough game at centre-back against Limerick. Cork enjoyed a relatively easy 3-15 to 4-5 victory, with Horgan collecting a third Munster medal. After his poor performance in the provincial decider, Horgan was dropped from the starting fifteen in favour of Pat Barry for Cork's All-Ireland final meeting with Wexford on 5 September 1976. Cork got off to one of the worst ever starts in an All-Ireland final and they trailed by 2-2 to no score after just six minutes. Cork rallied to level the score at the interval, with Horgan being introduced as a substitute for Pat Barry in the 42nd minute. Wexford had a two-point lead with ten minutes to go, however, three points from Jimmy Barry-Murphy, two from Pat Moylan and a held effort from Ray Cummins gave Cork a 2–21 to 4–11 victory.^[15] It was Horgan's second All-Ireland medal.

After an unhappy year at centre-back, Horgan was switched to his more natural left corner-back position in 1977. Cork qualified for a Munster final meeting with Clare, on a day when armed robbers made away with the takings from the gate of £24,579 during the second half of the game. Clare conceded an early penalty but they fought back to take the lead. A contentious red card for full-back Jim Power turned the tide for Cork and they fought on win by 4–15 to 4–10, with Horgan collecting a fourth winners' medal.^[16] The subsequent All-Ireland decider on 4 September 1977 was a repeat of the previous year as Wexford stood in the way of a second successive title for Cork. Seánie O'Leary played the game with a broken nose after being hit in the face by a sliotar in a pre-match warm-up while the two oldest men on the team, Denis Coughlan and Gerald McCarthy, gave noteworthy displays. Martin Coleman brought off a match-winning save from Christy Keogh in the dying seconds to foil the Wexford comeback. A 1–17 to 3–8 victory gave Horgan his third All-Ireland medal. His recall to the team was further vindicated when was presented with a second All-Star award in October of that year.

Horgan retained the left corner-back berth in 1978, adding attack to the defensive position by scoring three points against Waterford in the Munster semi-final. The subsequent provincial final was a repeat of the previous year, with a bumper crowd of 54,181 in attendance to see Cork face Clare. Before the game even began, Horgan was in trouble as he got stuck in traffic and had to persuade some Gardaí to escort him through the huge crowds to the stadium. Cork’s attack in the first half was a shambles, hitting thirteen wides and only leading by 0-5 to 0-3. Cork came out a different team after the interval and took a five-point lead. Clare rallied, however, a last-minute goal chance by Ger Loughnane went inches over the bar. Horgan was Cork's second highest scorer with four points, and the narrow 0-13 to 0-11 victory gave him a fifth Munster medal. On 3 September 1978, Cork faced Kilkenny in the All-Ireland final and the chance of securing a third successive championship. The game was not the classic that many expected. Cork were never really troubled over the course of the seventy minutes and a Jimmy Barry-Murphy goal helped the team to a 1–15 to 2–8 victory over their age-old rivals.^[17] This victory gave Cork a third All-Ireland title in succession and gave Horgan a fourth All-Ireland medal. He finished off the year by being named the Texaco Hurler of the Year.

Final victories

For the second time in his career, Horgan was awarded the Cork captaincy for the 1979 season. Cork had a relatively easy passage through the provincial series of games, with Horgan winning a sixth Munster medal following a 2-14 to 0-9 trouncing of Limerick. This victory paved the way for Cork to secure a record-equalling fourth successive All-Ireland title, and for Horgan to become the first Cork player since Seán Condon in 1944 to captain Cork to the four-in-a-row. Age and the exertions of the three previous campaigns finally caught up with Cork in the All-Ireland semi-final and a 2–14 to 1–13 defeat by Galway brought the four-in-a-row dream to an end.^[18]

Cork regrouped during the 1979-80 league and qualified for the final against Limerick. Horgan was at left corner-back, however, a late Limerick goal secured a 2-10 apiece draw. He was confined to the substitutes' bench for the subsequent 4-15 to 4-6 replay victory. For the third time in ten weeks, Cork and Limerick faced each other, however, this time it was in the Munster final and Cork were hoping to achieve a record-breaking sixth successive title. A narrow and unexpected 2-14 to 2-10 defeat brought an end to Cork's championship campaign.

For the second year in succession Cork qualified for the league decider with first-time finalists Offaly providing the opposition. Cork had scored 2-3 within the opening five minutes, however, Offaly fought back. Horgan scored two points from two 70-yards frees and collected his fourth league winners' medal following a 3-11 to 2-8 victory. Cork's championship campaign ended with a 2-15 to 2-13 Munster semi-final defeat by Clare. This was Horgan's last game for Cork as the recurrence of an Achilles tendon problem hastened his retirement from hurling.
