Game 1

Jacobs Field in Cleveland, Ohio

Boston jumped out to an early 1–0 lead with a lead-off home run by Nomar Garciaparra in the second inning off Indians' starter Bartolo Colón. Garciaparra set up the second run for the Red Sox when he led off the fourth inning with a double and then scored on an RBI single by Mike Stanley. Facing Cy Young Award winner Pedro Martínez, the Indians looked to be in serious trouble, but the ace of the Red Sox pitching staff left the game due to injury in the bottom of the fifth inning and was replaced by Derek Lowe. The Indians would tie the game in the bottom of the sixth with a two-run home run by Jim Thome, and Colón settled down and dominated the Red Sox hitters the rest of the way, striking out 11 in eight innings pitched. In the bottom of the ninth, the Indians handed Lowe a "L", walking the game off when Travis Fryman hit a game-winning single off Rich Garces with the bases loaded.

Game 2

Jacobs Field in Cleveland, Ohio

In Game 2, the Red Sox blew another lead. Behind Bret Saberhagen, the Red Sox built a 1–0 lead when José Offerman singled home Trot Nixon in the third off Indians starter Charles Nagy, but the Indians struck back and essentially put the game away in the bottom half. Omar Vizquel gave the Indians the lead when he tripled home Sandy Alomar Jr. and Kenny Lofton. Roberto Alomar doubled Vizquel home, and, after an out and a Jim Thome walk, Harold Baines hit a three-run home run to make it 6–1. That marked the end for Saberhagen. Next inning, the Indians loaded the bases off John Wasdin on two walks and a hit when Alomar's sacrifice fly scored Travis Fryman. After a walk re-loaded the bases, Thome's grand slam capped the scoring at 11–1 Indians, who were now one win away from the ALCS for the third straight year.

Game 3

Fenway Park in Boston, Massachusetts

When the series shifted to Fenway Park, so did the momentum. The Indians, too, would lose a starting pitcher to injury and blow a lead in Game 3. They struck first on a David Justice sacrifice fly off Ramón Martínez in the fourth, but, after shutting out the Red Sox for four innings, starting pitcher Dave Burba left with a strained forearm. Mike Hargrove chose to insert projected Game 4 starter Jaret Wright instead of rookie middle reliever Sean DePaula. The Red Sox quickly took the lead off Wright in the fifth on a Darren Lewis single and Trot Nixon sacrifice fly. Harold Baines's force out with runners on the corners tied the game in the sixth for the Indians. A lead-off home run by John Valentin untied the score for the Red Sox in the bottom of the sixth, but his error on Manny Ramirez's groundout with runners on first and third tied it back 3–3 in the top of the seventh. After Wright walked Merloni and hit Jason Varitek, Ricardo Rincón came on and got two outs, then Offerman walked to load the bases, John Valentin became the hero again with a double that scored Varitek and Lewis. Brian Daubach then hit a three-run home run to make it 8–3. Sean DePaula relieved Rincon and allowed a walk and single before Lou Merloni's RBI single made it 9–3. Derek Lowe earned the win 2+1⁄3 innings of relief while Rod Beck pitched a scoreless ninth to seal the victory.

Game 4

Fenway Park in Boston, Massachusetts

Because presumed starter Jaret Wright had been used in relief the previous day, and no emergency starter had been included on the playoff roster, the Indians felt forced to start Bartolo Colón on three days' rest for the first time in his career, even though he had gone eight innings in cold weather in the first game. This time, he was not up to the challenge. Neither he nor the thin bullpen behind him could stop the barrage of Red Sox runs. Colón himself was hammered for seven runs in one-plus innings pitched, and reliever Steve Reed was tagged for eight. The Indians struck in the top of the first: Kenny Lofton hit a leadoff double, moved to third on a sacrifice bunt, and scored on Roberto Alomar's groundout off Red Sox starter Kent Mercker, but in the bottom of the inning, John Valentin's two-run home run after a leadoff walk put the Red Sox up 2–1. The Indians tied the game in the second on Sandy Alomar's sacrifice fly off Mercker, who was taken out after just 1+2⁄3 innings and relieved by Rich Garces. In the bottom of the inning, three consecutive singles put the Red Sox back in front, then Trot Nixon's double scored two. José Offerman's two-run home run knocked Colón out of the game. Next inning, Nixon's sacrifice fly with runners on first and third put the Red Sox up 8–2, then Valentine's second home run of the game increased the lead to 10–2. Next inning, Jason Varitek's RBI double with two on made it 11–2 Red Sox. After Nixon walked with two outs to load the bases, Offerman's single scored one, then Valentin's double cleared the bases, making the score 15–2. Valentine went 4 for 5 with 7 RBIs. In the top of the fifth, Cleveland responded against Tim Wakefield. With runners on first and third, Wil Cordero and Richie Sexson hit back-to-back RBI singles; after Jim Thome walked to load the bases, John Wasdin relieved Wakefield, who faced 4 hitters and retired none, and allowed a sacrifice fly to Travis Fryman, then walked Sandy Alomar to reload the bases. Rhéal Cormier relieved Wasdin and walked Lofton to force in another run before striking out Omar Vizquel and Roberto Alomar to end the inning, the score now 15–6. In the bottom half, Mike Stanley hit an RBI triple before Varitek's two-run home run made it 18–6. In the seventh, Nixon's double off Paul Assenmacher scored two before Nixon scored on Offerman's single. In the eighth, pitcher Paul Shuey allowed a walk and subsequent double before Scott Hatteberg's RBI single made it 22–6 Red Sox, Shuey then walked two to force in the Red Sox's last run while the Indians scored their last run of the game on a Wil Cordero home run in the ninth off Tom Gordon. The Red Sox's 23–7 blowout forced a Game 5 in Cleveland. The 23 runs scored by the Red Sox were, and still remain, an MLB record for most runs scored by one team in a single postseason game.

Game 5

Jacobs Field in Cleveland, Ohio

In Game 5, Charles Nagy started for Cleveland and Bret Saberhagen started for Boston, both on only three days' rest. In the top of the first inning, Brian Daubach singled with two outs before Nomar Garciaparra homered to put the Red Sox up 2–0, but in the bottom of the inning, Kenny Lofton drew a leadoff walk, stole second, and scored on Omar Vizquel's double. Two outs later, Jim Thome's home run put the Indians up 3–2. Next inning, Wil Cordero hit a leadoff single before Travis Fryman's two-run home run made it 5–2 Indians and knock Saberhagen out of the game. In the third, however, John Valentin's groundout with runners on first and third cut the Indians' lead to 5–3. After a double and intentional walk loaded the bases, Troy O'Leary's grand slam put the Red Sox up 7–5. In the bottom of the inning, Roberto Alomar and Manny Ramirez hit back-to-back leadoff doubles off Derek Lowe before Thome's second home run of the game put the Indians back on top 8–7. The Red Sox, though, tied the game in the fourth on Valentin's sacrifice fly off Sean DePaula with the run charged to Nagy.

In the bottom of the fourth inning, Red Sox manager Jimy Williams opted to replace Derek Lowe with the ailing Pedro Martínez, who had left Game 1 with a back injury. This decision proved wise, as Pedro pitched spectacularly, throwing six hitless innings, striking out eight and walking three. Rookie reliever Sean DePaula, whom Hargrove had refused to use in Game 3 when it mattered and compromised his rotation as a result, matched Pedro for three innings. Despite his mastery of the Sox, which since the middle of Game 3 had been rare for Cleveland pitchers, Hargrove removed him and opted to use inconsistent setup man Paul Shuey for the seventh inning. The Red Sox would then take the lead on the back of a Troy O'Leary three-run home run after an intentional walk of Nomar Garciaparra, and added another run in the ninth off Michael Jackson when Daubach and Garciaparra hit back-to-back one-out doubles. They won the game 12–8 to clinch the series, after the conclusion of which Mike Hargrove was dismissed as Cleveland manager.
