1986 American League Championship Series

Boston won the series, 4–3

The Eastern division champion held home field advantage for the third consecutive year in the ALCS. Between 1969-84, the home field advantage alternated between the West in odd-numbered years and the East in even-numbered years. In 1987, that alternation resumed and continued through 1993..

Angels left fielder Brian Downing went 2-for-5 with four RBI and Mike Witt pitched a five-hit complete game, allowing just one run in the sixth on Marty Barrett's RBI single after a two-out walk and single. After getting two outs, Red Sox starter Roger Clemens walked two in the second before Ruppert Jones's RBI single, Wally Joyner's RBI double, and Downing's two-run single put the Angels up 4–0. Gary Pettis's RBI single with two on extended their lead to 5–0, the run unearned due to shortstop Spike Owen's throwing error to first on Bob Boone's ground-ball. In the eighth, Dick Schofield singled with one out, stole second and scored on Boone's single. After a Pettis single, Joe Sambito relieved Clemens and allowed a two-out walk to load the bases, then Downing's two-run single capped the game's scoring at 8–1 as the Angels took a 1–0 series lead.

The next day, the tables were turned. The Red Sox struck first in the bottom of the first when Wade Boggs hit a leadoff triple off Kirk McCaskill and scored on Marty Barrett's double. Barrett's bases-loaded RBI single next inning made it 2–0 Red Sox, but Bill Buckner hit into an inning-ending double play to limit the damage. Dick Schofield's bases-loaded single in the fourth cut the Red Sox's lead to 2–1, but Bruce Hurst retired the next two batters to keep them in front. Next inning, Wally Joyner's home run tied the game, but in the bottom half, Dwight Evans's RBI double with two on put the Red Sox ahead for good, 3–2. Boston padded their lead in the seventh. An error, single and walk loaded the bases with one out before another error on Evans's ground ball allowed one run to score and keep the bases loaded, then a third error on Rich Gedman's force out allowed two more runs to score. Next inning, Buckner's sacrifice fly with runners on first and third off Gary Lucas made it 7–2 Red Sox before Jim Rice's home run off Doug Corbett capped the game's scoring at 9–2. Hurst pitched a complete game as the Red Sox tied the series 1–1 heading to California.

In Game 3, the Red Sox struck first in the second on Rich Gedman's RBI single with two on off John Candelaria, but after pitching five shutout innings, Oil Can Boyd allowed a game-tying RBI single to Reggie Jackson in the sixth. Dick Schofield's two-out home run in the seventh put the Angels up 2–1. After Bob Boone singled, Gary Pettis's two-run home run extended their lead to 4–1. The Red Sox scored two runs in the eighth on Donnie Moore's balk with runners on second and third and Gedman's RBI single, but the Angels padded their lead in the bottom half on Ruppert Jones's sacrifice fly off Calvin Schiraldi. Moore pitched a scoreless ninth as the Angels went up 2–1 in the series with a 5–3 win.

Roger Clemens, the Game 1 loser for the Red Sox, started Game 4, and was solid for most of the game. Boston put up a run in the sixth on Bill Buckner's RBI double with two on off Don Sutton. In the eighth, Spike Owen hit a leadoff single off Vern Ruhle, moved to third on a groundout and wild pitch, then scored on Marty Barrett's single. Chuck Finley relieved Ruhle and a passed ball and error on Buckner's ground ball allowed Barrett to score to make it 3–0 Red Sox. Another error and walk off Doug Corbett loaded the bases, but Rich Gedman hit into a forceout to end the inning. In the bottom of the ninth, Doug DeCinces led off with a home run. After the next batter grounded out, Dick Schofield and Bob Boone singled. After coming within two outs of a complete game, Clemens was removed, and Boone was replaced with a pinch runner. Gary Pettis, batting next, doubled to score Schofield. Ruppert Jones was intentionally walked to load the bases, a fatal mistake, as two batters later, Brian Downing was hit by a pitch, bringing in the tying run.

Angels relief pitcher Doug Corbett pitched a perfect tenth and eleventh innings, and California broke through in the bottom of the 11th. Jerry Narron scored on Bobby Grich's one-out single off Calvin Schiraldi, giving California a 4–3 win and a 3–1 series lead.

Heading into Game 5, California looked set to earn their first-ever trip to a World Series. Rich Gedman's two-run home run in the second put the Red Sox up 2–0, but Bob Boone's home run off Bruce Hurst in the third cut the lead to 2–1. Bobby Grich, the previous night's hero, hit a two-run home run to give the Halos a 3–2 lead in the sixth inning; Red Sox center fielder Dave Henderson had tried to leap at the wall to catch Grich's long fly ball, but ended up deflecting it over the fence. The Angels added to their lead in the seventh off Bob Stanley on Rob Wilfong's RBI double with two on and Brian Downing's bases-loaded sacrifice fly.

In the ninth, Mike Witt allowed a leadoff single to Bill Buckner but struck out Jim Rice, putting him two outs away from his second complete game victory of the series. The next batter, Don Baylor, hit a two-strike, two-run home run to pull the Red Sox within one run. After retiring the next batter, Witt was replaced. Gary Lucas was brought in to face catcher Rich Gedman who had been 3 for 3 in the game against Witt, including a double and a home run. Lucas, on the other hand, had a history of striking Gedman out. But with his very first pitch, Lucas hit Gedman, and was replaced by Donnie Moore. The Angels closer brought his team within one strike of its first-ever AL pennant, but Henderson caught hold of a Moore forkball and launched a home run into the left field stands, stunning the hometown crowd and greatly redeeming himself for his earlier miscue. Boston had taken a 6–5 lead.

The lead would not last, however, as in the bottom of the ninth, Bob Boone singled off Stanley, and Ruppert Jones pinch-ran for him. Gary Pettis sacrificed Jones to second, and Wilfong singled him home off Joe Sambito, tying the game. Dick Schofield then singled, sending Wilfong to third, and Downing was intentionally walked to load the bases with only one out. All of Boston's top-half heroics would have been washed away with a mere sacrifice fly at this point. But instead, Doug DeCinces only managed to hit a short fly ball to right field. Grich's subsequent line-out to pitcher Steve Crawford ended the inning.

The teams settled down and the tenth inning was again scoreless, but the Red Sox loaded the bases in the top of the 11th off Donnie Moore on a hit-by-pitch and two singles for Henderson. He hit a sacrifice fly, scoring Baylor with the go-ahead run. Calvin Schiraldi then retired the Halos in order in the bottom of the 11th, completing a shocking comeback and sending the series back to Boston.

Still reeling from their Game 5 loss, the Angels struck first in the top of the first off Oil Can Boyd on back-to-back two-out RBI doubles by Reggie Jackson and Doug DeCinces after a one-out walk, but the Red Sox tied the game in the bottom of the inning off Kirk McCaskill without a hit. With runners on second and third and one out via two walks and a groundout, a passed ball and Jim Rice's groundout scored both runners. In the third, after back-to-back leadoff singles, Marty Barrett's RBI double put the Red Sox up 3–2, then Bill Buckner's RBI single extended their lead to 4–2. After a forceout at home, Don Baylor's two-run single (aided by first baseman Bobby Grich's throwing error) and Dwight Evans's RBI single made it 7–2 Red Sox. Dave Henderson's bases-loaded groundout off Doug Corbett in the fifth made it 8–2 Red Sox. Brian Downing hit a home run in the top of the seventh off Boyd, but in the bottom of the inning, Spike Owen's two-run triple off Corbett after a single and walk made it 10–3 Red Sox. The Angels got a run in the eighth off Bob Stanley on shortstop Owen's throwing error on Rob Wilfong with Dick Schofield at second, but could not score again as the Red Sox's 10–4 win forced a deciding Game 7.

In Game 7, the Red Sox loaded the bases in the second off John Candelaria with no outs on an error, single and walk. Rich Gedman's groundout scored a run and after an intentional walk reloaded the bases, Wade Boggs's two-run single made it 3–0 Red Sox. In the fourth Dave Henderson reached third on an error, then scored on Spike Owen's single. After a two-out walk, Jim Rice's three-run home run made it 7–0 Red Sox, all runs unearned. Dwight Evans's home run in the seventh off Don Sutton made it 8–0 Red Sox. The Angels scored their only run of the game on Doug DeCinces's RBI single off Calvin Schiraldi, the run charged to starter Roger Clemens. Schiraldi pitched two innings to close as the Red Sox advanced to the World Series with an 8–1 win after trailing the series three games to one. It was their first pennant in 11 years.
