Detroit's Rotation Is Three Deep, and That's Being Generous

Behind Tarik Skubal, the Tigers are running Keider Montero, Framber Valdez, and Casey Mize — and that is essentially the whole conversation. Montero has been the quiet surprise of the second half, posting a 3.06 ERA over 109 innings with a WHIP under 1.00. Valdez has been serviceable but hittable at 4.05. Mize, at 3.46, has been better than his 4-9 record suggests. None of them are Skubal, and none of them are close.

The problem is that Skubal himself is now a question mark. His admission last week that he regrets skipping an offseason elbow MRI is the kind of thing that doesn't leave your head once you've heard it. He's at 101.7 innings through 18 starts, and if Detroit is going to make any kind of run at that wild card — they're 2.5 games back with 60 to play — he needs to be healthy for most of it. Jack Flaherty is on the 15-day IL with right flexor inflammation, Reese Olson is on the 60-day, Brant Hurter is on the 60-day. The depth behind the top four isn't a depth chart so much as a list of names on medical paperwork.

What the last 10 games tell you is that this rotation has been carrying more weight than the offense lately. Detroit is scoring 3.3 runs a game over that stretch — down sharply from where they were — and they still went 5-5. The arms kept them in games the lineup couldn't win cleanly. That's fine for a week and a half. It's not a second-half plan. With the trade deadline a week out, my read is the rotation is the one area where an addition actually matters — not a star, just a reliable fifth option who can eat innings without ending up on the 60-day by September.
