The St. Louis Cardinals have a rotation problem and it’s not subtle. Their current group of starters averages fewer than 40 career MLB starts per man. That number includes Dustin May, who hasn’t thrown 100 innings in a season since 2021, and Matthew Liberatore, who still hasn’t proven he can handle a full workload. The team traded Sonny Gray last offseason and never replaced him. So here they are, six weeks from the August 3 deadline, needing a front-line starter and holding prospect capital to make it happen.
Reid Detmers should be the target. The Angels left-hander turns 27 this summer and has quietly put together the best season of his career. Over 15 starts he has a 3.68 ERA, a 1.00 WHIP and 100 strikeouts in 88 innings. His last five outings have been absurd: 1.36 ERA with 39 punchouts across 33 innings. The underlying numbers back it up too. Detmers ranks sixth in MLB in FIP at 2.91 and sixth in xERA at 2.92. Those aren’t fluky numbers. That’s a pitcher whose stuff is legitimately elite.
His slider generates whiffs on nearly 36 percent of swings. His four-seamer sits at 94 miles per hour. And he has two full years of club control remaining after this season at a salary that won’t break any budget. For a team like St. Louis that wants to compete when their young position players are ready in 2027 and 2028, Detmers fits the timeline perfectly.
The Angels are expected to sell. They are not close to contending and Detmers is their most valuable trade chip. So what would a deal actually look like?
A trade that makes sense for both sides
The Cardinals have the prospect depth to get this done without gutting their system. Here is the framework that works for both franchises.
St. Louis sends left-hander Ixan Henderson and outfielder Tai Peete to Los Angeles for Detmers. Henderson won the Texas League ERA title in 2025 with a 2.59 ERA and 134 strikeouts in 132 innings at Double-A Springfield. He profiles as a future mid-rotation arm and gives the Angels a young lefty to build around. He also dealt with an elbow flexor strain this spring, which creates some risk that makes him more expendable from the Cardinals side.
Peete is a 20-year-old outfielder with 60-grade speed and plus raw power. He hit for the cycle at High-A Peoria earlier this season and has 70 career minor league stolen bases. He came over from Seattle in the Nolan Donovan trade and immediately gives the Angels an athletic, high-upside outfield prospect they can dream on.
For the Angels, that package delivers two young, controllable players with real paths to the majors. For the Cardinals, they give up one prospect with injury history and another who is still years away from contributing while getting a 26-year-old ace with proven strikeout stuff and multiple years of team control. That is exactly the kind of trade a front office should make when it has pitching needs and prospect depth.
The Cardinals have the organizational depth to absorb losing Henderson and Peete. Their outfield is crowded at the upper levels and they have other arms in the pipeline. The Angels get two building blocks for a rebuild that needs exactly that. This trade works for both sides and the only question is whether the Angels actually pull the trigger.
