Perkins is a converted reliever who landed in the rotation after Severino went to the 60-day IL with a shoulder injury. He has been hittable — 20 hits and 15 runs allowed in his last 18 innings, with a 6.32 ERA in road starts specifically. His last crack at the Angels on June 21 went 5 innings and produced 4 earned runs, though he did punch out 8. Detmers, meanwhile, looks very different from the outside versus in this specific matchup. He has been sharp in June, allowing just 6 runs in 26 innings this month and logging 8-plus strikeouts in each of his last 4 home starts. The problem: in 8 career appearances against the A's, Detmers carries a 8.10 ERA. His June 21 start against them cost him 5 earned runs in 6 innings, and that's not an outlier for him against this lineup.

The Angels are already playing shorthanded. Mike Trout is on the 10-day IL with a hamstring issue. Starters Yusei Kikuchi and Jack Kochanowicz — who had successful Tommy John surgery — are both on the 60-day IL. Grayson Rodriguez is rehabbing a back injury. The rotation and lineup depth are both thinner than the standings suggest. Oakland has its own holes: Zack Gelof (hand) is on the 10-day IL, Jacob Wilson (shoulder) is day-to-day, and Brent Rooker (knee) is also sidelined. But the A's have been managing around those absences well enough to win 2 straight going into tonight.
The honest read here is that Detmers has the better overall profile and the home-field advantage, but he's walking into a matchup where Oakland's lineup historically feasts on him. Perkins is a work-in-progress rotation piece with rough road numbers who somehow went 1-0 with a 5.25 ERA in career starts against the Angels. None of it is clean. That's the game: Detmers vs. his own Oakland problem, on one side, and Perkins trying to stay afloat long enough to hand it to a bullpen that's been carrying a lot of the load.
