In a game that will be etched into Seattle baseball lore for generations, the Mariners clawed their way to a 3-2 victory over the Detroit Tigers in Game 5 of the ALDS on Friday night at T-Mobile Park, capping a 15-inning odyssey that stands as the longest winner-take-all contest by innings in MLB postseason history. The walk-off drama unfolded in the bottom of the 15th when Jorge Polanco ripped a game-winning single through the right side with the bases loaded and one out, scoring J.P. Crawford from third and sending the sellout crowd of over 47,000 into delirium. This triumph propels Seattle to the American League Championship Series—their first since 2001—for a matchup against the Toronto Blue Jays starting Sunday in Toronto.
The evening’s pitching duel set the tone early, with Mariners starter George Kirby and Tigers ace Tarik Skubal trading zeros through the first four frames. Skubal, the AL Cy Young frontrunner, was untouchable, fanning seven straight Mariners to set a postseason record and becoming the first pitcher in history to notch double-digit strikeouts with zero walks through four innings. Kirby matched him stride for stride, surrendering just three hits and striking out six over his outing.
Seattle drew first blood in the second when Josh Naylor laced a double into the left-field corner, promptly swiped third—the first steal of third base against Skubal all season—and scampered home on Mitch Garver’s deep sacrifice fly to center, putting the Mariners up 1-0. The lead held until the middle innings, when Detroit’s bullpen arm Gabe Speier faltered, serving up a two-run homer to Kerry Carpenter that flipped the script and gave the Tigers a 2-1 edge.
Enter the seventh: a managerial mind-meld that swung momentum back to Seattle. With the Tigers leading and a runner in scoring position, Mariners skipper Dan Wilson initially signaled for Dominic Canzone to pinch-hit for Garver, prompting Tigers manager A.J. Hinch to summon lefty Tyler Holton from the ‘pen. Wilson pivoted brilliantly, opting instead for switch-hitter Leo Rivas—pinch-hitting in his first career playoff at-bat on his 28th birthday. Rivas, batting right-handed, smoked a two-out RBI single to left on the second pitch, knotting the score at 2-2 and becoming just the third player in postseason history (and first since 1993) to deliver a birthday pinch-hit knock.
From there, it devolved into a bullpen chess match of endurance and escape artistry. Both sides’ relievers locked down the diamond inning after grueling inning, with Seattle’s arms—bolstered by Kirby’s early gem—edging out Detroit’s staff despite Skubal’s Herculean line: six innings, one run allowed, 13 strikeouts on 99 pitches. The game stretched into uncharted territory, testing the mettle of players and fans alike in a series-clinching saga that evoked the Mariners’ haunted playoff past.
The ghosts were finally exorcised in the 15th. Crawford opened with a sharp single to center off Tigers reliever Will Vest. Randy Arozarena took one for the team, getting plunked to put runners at first and second. Cal Raleigh lofted a fly to center deep enough to tag up Crawford to third. With the infield drawn in, Hinch opted to intentionally walk superstar Julio RodrÃguez, loading the bags for Polanco. The veteran infielder didn’t flinch, lining a 1-1 offering into right for the 3-2 walk-off dagger.
For the Tigers, it was a gritty but gut-wrenching end to a Cinderella run, powered by Carpenter’s blast and Skubal’s dominance but undone by late-inning fate. Seattle, meanwhile, channeled pure resilience—Naylor’s speed, Rivas’s birthday magic, and Polanco’s clutch stroke—to rewrite their narrative. As the Big Unit himself, Randy Johnson, might say: The M’s are dancing again.
