Saturday's 1:10 PM ET first pitch is the bridge between Tarik Skubal's Friday start and Justin Verlander's Sunday return from the 60-day IL, which means the middle of this series is the soft underbelly. Detroit had Troy Melton penciled in to take the ball this weekend but he was scratched Monday vs. Houston with lower-back tightness, and Jack Flaherty just hit the 15-day IL with a peroneal strain. Whoever the Tigers run out there is pitching on borrowed time in a banged-up rotation. The White Sox, meanwhile, are the story nobody saw coming. Will Venable's team is 38-33, has gone 11-5 over its last 16, and already took a series off the Dodgers at home before getting punched in the mouth 12-2 by the Yankees on Tuesday. That Yankee Stadium beating is the only real blemish in a month where Chicago has actually looked like a big-league team — and they cash in this weekend if they can put Detroit's bullpen to work early. Detroit is sitting at 30-43 and just got swept-ish by Cleveland (2 losses and a rain-tie) before splitting the first 2 in Houston. The lineup is also short-handed: Gleyber Torres sat Tuesday with a side issue, Colt Keith took a fastball off the wrist (x-rays negative, but he's day-to-day), and Parker Meadows and Javier Baez are both still on the 60-day. That's a lot of regulars to replace against a Sox club starting to swing it. Chicago is dealing with its own stuff — Hagen Smith just got shut down 2 weeks with a shoulder impingement, Noah Schultz and Jordan Hicks are on rehab assignments at Triple-A Charlotte, and Munetaka Murakami is still working back from a hamstring after a PRP injection. But the difference is the Sox are winning games while waiting on those guys. Detroit isn't. The pitching-matchup card above lays out who's actually toeing the rubber, but the bigger picture is simple: the Tigers need to survive Saturday to get to Verlander on Sunday, and the Sox have every reason to think they can keep the foot down. Anchor this one to the Friday-Skubal, Sunday-Verlander framing — the middle game is where the series gets decided.
