First pitch is 12:40 PM CT at Comerica, and the matchup card tells the story: Luis Castillo (2-5, 5.53) against Jack Flaherty (1-7, 5.31). Castillo's last outing was 4 scoreless innings against the Athletics on May 25, but per DK Network two of his last three appearances were out of the bullpen, so the leash here is a real question. Flaherty walked into his last start at Tampa Bay and spun 5 innings of shutout ball for his first win of the year.

The Mariners come in at 34-31 and just laid a 4-0 beating on Detroit on Saturday. They're doing it without Cal Raleigh (oblique, starting a rehab assignment with High-A Everett on Sunday) and likely without J.P. Crawford again — he sat Saturday with a hand issue. The Tigers, meanwhile, were riding a 4-game heater before getting blanked. A.J. Hinch's rotation is held together with tape: Skubal on a rehab start, Verlander targeting a return next week against Minnesota, and Mize and Jobe still working back.

Pinnacle has Seattle at -115 with the total parked at 8.5 (under -115), which feels like the market shrugging at both rotations and trusting the bullpens to keep things from getting silly. The Mariners are technically favored, but a -115 number for a road team with a 5.53 ERA starter against a team that just won 4 straight is the book telling you it doesn't trust either side much.

The Flaherty wild card is real. Per Motor City Bengals, his walk rate has spiked from 6% in 2025 to 14% this year, which is how a guy with stuff this clean ends up 1-7. If the strike zone shows up, that Tampa start was a glimpse of what the Tigers paid for. If it doesn't, Seattle's lineup — Raleigh-less but still dangerous — has every reason to make him pay early.

Bottom line: a get-away day matinee between two clubs in very different places in the standings, with starters who are each one bad inning away from handing it to a reliever. Take the under at your own risk — both of these guys can implode, but both can also limp through 5. Lean Seattle, expect chaos, and don't be shocked if this thing is decided by the 7th-inning matchups more than anything Castillo or Flaherty does.
