The 1987 AL playoffs opened at the Hubert H. Humphrey Metrodome, with the Tigers throwing Doyle Alexander against the Twins' Frank Viola. In the bottom of the second, the Twins opened the scoring when third baseman Gary Gaetti homered off Alexander to give Minnesota a 1–0 lead. However, Detroit answered back the very next half-inning, as catcher Mike Heath homered to center field to tie the game. The game remained tied until the bottom of the fifth, when the Twins erupted for three runs. Gaetti led off the inning with his second round-tripper of the game, and Randy Bush followed by stroking a triple to right field and coming home on a double by Tom Brunansky. Steve Lombardozzi sacrificed Brunansky to third, and he scored on a subsequent base hit by Dan Gladden to make it 4–1.

Beginning in the top half of the sixth, however, Detroit staged a comeback. Kirk Gibson hit a home run that inning, and then Heath ripped an RBI single in the seventh that scored Larry Herndon to cut Minnesota's lead down to one. In the top of the eighth, the Tigers took a one-run lead with a pair of sacrifice flies off Twins reliever Jeff Reardon that scored Gibson and Alan Trammell.

In the bottom of the eighth, however, Minnesota took the lead for good. A double by Kirby Puckett brought Gladden home to tie the game, and Don Baylor and Brunansky drove in the go-ahead runs off Willie Hernández with a single and double, respectively. A single by Johnny Grubb and a walk to Lou Whitaker was all the Tigers could muster against Reardon in the ninth, as Gibson struck out to give the Twins an 8–5 victory and a 1–0 lead in the series. This was the Twins' first postseason win since Game 6 of the 1965 World Series.

For Game 2, the Twins sent Bert Blyleven to the hill against Detroit's ace, Jack Morris. In the top of the second, the Tigers opened the scoring when Chet Lemon hit a two-run home run off Blyleven. In the bottom half of the inning, however, the Twins stormed back, as Gaetti doubled to right and scored on another double by Brunansky. After a walk to Greg Gagne, catcher Tim Laudner hit the third double of the inning off Morris, scoring both Brunansky and Gagne for a 3–2 Minnesota lead.

The Twins extended their lead in the fourth, as Bush singled and then stole second and third. After consecutive walks to Brunansky and Gagne, Gladden singled to left to drive in Bush and Brunansky. Kent Hrbek then added a homer in the fifth, giving Minnesota a 6–2 lead. Tigers second baseman Lou Whitaker touched Blyleven for a homer in the eighth, but the Twins hurler would allow nothing more. Former Tiger Juan Berenguer struck out the side in the ninth to hand the Twins a 6–3 victory and a 2–0 series lead.

The Series shifted to Detroit for Game 3, with the Tigers' Walt Terrell facing the Twins' Les Straker. The two pitchers matched zeroes for the first two-and-a-half innings until the bottom of the third, when Detroit's Pat Sheridan doubled to left, moved to third on a single by Whitaker, and scored on a force out by Gibson that sent Whitaker to third. After Gibson stole second, a balk by Straker scored Whitaker, and a single by Trammell brought in Gibson. A double by Herndon then scored Trammell and Lemon to give the Tigers a 5–0 lead.

In the top of the fourth, the Twins cut Detroit's lead to 5–2 with a Gagne home run and a Bush single that scored Hrbek, and in the sixth they reduced the lead down to one with a two-run homer by Brunansky. In the top of the seventh, a two-out single by Gaetti drove in Gladden and Gagne to give the Twins a 6–5 lead and put them on the cusp of taking a stranglehold on the series.

Facing the prospect of blowing a 5–0 lead and falling behind three games to none, the Tigers rallied in the bottom of the eighth. Minnesota brought in Reardon to get a two-inning save. After a lead-off single by Larry Herndon. After Jack Morris pinch ran for Herndon, Reardon got Tom Brookens to pop out to Hrbek on a sacrifice bunt attempt. Pat Sheridan, 1 for 6 lifetime versus Reardon, hit the first pitch he saw into the upper deck in right field for a two-run home run that restored Detroit's lead, 7–6. In the top of the ninth, Mike Henneman retired the Twins in order to put the Tigers back in the Series, which now stood at 2–1 for Minnesota.

The fourth game of the series matched Viola against Tiger left-hander Frank Tanana, who had thrown a 1–0 complete-game shutout over the Toronto Blue Jays on the final day of the regular season to punch Detroit's playoff ticket.

In the bottom of the first, the Tigers gave Tanana a 1–0 lead when Lou Whitaker walked to lead off the inning and eventually scored on a throwing error by Twins shortstop Greg Gagne. However, in the top of the third, Kirby Puckett homered off Tanana to tie the game, then Gagne added a homer in the top of the fourth to give Minnesota a 2–1 lead. The Twins made it a 3–1 lead in the fifth when Puckett came home on a Gary Gaetti sacrifice fly, but the Tigers came to within a run in the bottom of the fifth when an infield hit by Kirk Gibson scored Whitaker.

In the top of the sixth, Gagne doubled, moved to third on a wild pitch, and scored on a base hit by pinch-hitter Gene Larkin to give Minnesota a 4–2 advantage. In the bottom half of the inning, the Tigers again clawed to within a run when pinch-hitter Dave Bergman followed up singles by Chet Lemon and Darrell Evans with a single of his own, scoring Lemon and moving Evans to second. After Mike Heath sacrificed Evans to third and Bergman to second, Twins manager Tom Kelly pulled Keith Atherton in favour of Juan Berenguer. However, the Tiger rally was squelched when catcher Tim Laudner picked a stunned Evans off third and Berenguer induced a flyout from Jim Morrison to end the inning.

In the eighth, the Twins restored their two-run lead when Laudner reached on an error by Evans (who was playing third base, as Bergman had stayed in the game as the first baseman) and came home to score on a single by Steve Lombardozzi. In the ninth, Reardon managed to preserve a 5–3 Twins win, putting them one victory away from the pennant. This was the first road postseason victory for the Minnesota Twins/Washington Senators since Game 1 of the 1925 World Series.

In what would turn out to be the last postseason game played at Tiger Stadium, the Twins would send Blyleven to the mound to face the Tigers' Doyle Alexander.

In the top of the second, Minnesota drew first blood when Tom Brunansky doubled home Gary Gaetti and Randy Bush, but was thrown out trying to stretch his hit into a triple. Dan Gladden and Kirby Puckett added RBI base hits of their own to give the Twins a 4–0 lead, and Tigers manager Sparky Anderson replaced Alexander with Eric King.

As they had several times during the series, Detroit cut the Twins' lead down to one run in the bottom of the fourth, when Kirk Gibson scored on an Alan Trammell single and Matt Nokes followed with a two-run homer that scored Trammell. In the top of the seventh, however, the Twins restored their two-run lead when Kent Hrbek singled, moved to second when Gaetti was hit by a pitch, took third on a wild pitch by King, and plated on a sacrifice fly by Bush.

In the eighth, Tiger reliever Mike Henneman, who replaced King in the seventh, allowed a double to Gladden and a walk to Gagne. Puckett then grounded to Henneman, who attempted to initiate a double play. However, first baseman Darrell Evans misplayed the ball for his second error of the series, allowing Gladden to score and make it a 6–3 Minnesota lead. Although Chet Lemon homered for Detroit in the bottom half of the inning to make it 6–4, the Twins decisively stormed ahead in the top of the ninth. Brunansky hit his second home run of the postseason, and Gladden and Gagne followed with consecutive RBI doubles off Henneman and Jeff Robinson.

The Twins sent Reardon, who entered the game in the bottom of the eighth, to the hill to close out the series in the bottom of the ninth. Although an RBI single by Gibson scored Jim Morrison, the Minnesota stopper allowed nothing more, as Matt Nokes grounded out to Reardon to end a 9–5 Twins victory and clinch the franchise's first World Series berth since 1965.

This was the last postseason appearance for the Tigers until 2006.
