The Detroit Tigers host the Colorado Rockies on Saturday, September 12, 2026, at Comerica Park for a 1:10 PM ET first pitch. Detroit sends right-hander Andrew Sears to the mound in what figures to be an intriguing late-season matchup, with Tanner Gordon taking the ball for Colorado. With rosters expanded and playoff positioning still in play across the league, this is not a game either club can afford to sleepwalk through. Catch it on Detroit SportsNet or on the radio at WXYT 97.1 FM.

Starting Pitchers: Andrew Sears vs. Tanner Gordon

The pitching matchup features two arms the baseball world is still forming its full verdict on. Andrew Sears gets the nod for Detroit, and this is the kind of late-September turf where young starters either prove they belong or expose why the roster decisions ahead will be complicated. There are no ERA or win-loss lines available for Sears heading into today's start, which only adds to the intrigue — watch how he handles a Colorado lineup that has enough athleticism up top to cause problems.

Tanner Gordon draws the assignment for the Rockies. Like Sears, Gordon's full statistical profile is not available for this start, so the scouting will happen in real time at Comerica Park. What we do know is that pitching away from Coors Field tends to flatter Colorado hurlers — the altitude adjustment works in reverse when these guys pitch at sea level, and Gordon could be sharper than expected.

Detroit Tigers Lineup to Watch

• Kevin McGonigle leads off at third base — an interesting choice at the top of the order that puts a young infielder in a high-visibility role.
• Hao-Yu Lee bats second at second base, giving the Tigers a contact-oriented presence early in the lineup.
• Colt Keith slots in third as the DH — one of the more important bats in this order, and a player who needs to drive traffic if Detroit is going to put runs on the board early.
• Riley Greene hits cleanup in left field. Greene in the four-hole is a statement of where Detroit's offensive trust currently lives.
• Eduardo Valencia catches and bats fifth, followed by Max Clark in center field — two younger pieces the organization is clearly invested in developing through regular at-bats.
• Spencer Torkelson bats seventh at first base. Torkelson's spot in the order is worth monitoring — his production, or lack of it, will tell you something about where this day goes.

Colorado Rockies Lineup to Watch

• Jake McCarthy leads off in left field, giving Colorado a speed-oriented table-setter.
• Hunter Goodman catches and bats third — he's the middle-of-the-order threat Detroit's pitching staff will need to address early and often.
• TJ Rumfield at first base bats cleanup for the Rockies, providing the lineup's primary power presence.
• Ezequiel Tovar bats ninth at shortstop — don't let the lineup spot fool you, Tovar is a legitimate defender and can make noise in any count.

Keys to the Game

• Sears's command: If Sears can establish himself in the strike zone early and limit free passes, Detroit controls this game. If he labors and runs deep counts, the Rockies' athleticism becomes a real factor.
• Greene and Keith producing: The middle of Detroit's order — Keith third, Greene fourth — needs to convert when runners are on. Those two bats are the engine.
• Torkelson's day: A productive afternoon from Torkelson in the seven-hole could signal something larger about where he is right now. A quiet one extends questions.
• Colorado's Goodman and Rumfield: The Rockies' three-four punch is the clearest threat to Detroit's run prevention. Keep them in the park and Sears has a chance.

Prediction

Detroit gets the edge here at Comerica Park. The home lineup has enough pieces — Greene, Keith, Clark — to scratch out runs against a Rockies pitching staff operating away from its altitude home. If Sears is sharp through five innings and the Tigers bullpen holds serve, expect a 4-2 Detroit win in front of the home crowd. The late-season calendar matters, and the Tigers need to take care of business on their home turf.
