1 last-minute trade Astros must make before deadline

The Houston Astros have a rotation that’s been battered by injuries all season, and the clock is running out to fix it before Monday’s 6 p.m. ET deadline. Detroit right-hander Casey Mize was scratched from his start Friday as a precaution against injury risk amid trade buzz, a clear sign he’s drawing real interest around the league. If the Astros want a genuine impact arm rather than a depth piece, Mize is the last-minute swing they need to make.

Why Mize Is the Astros’ Best Available Target

Mize has quietly delivered the best season of his career in Detroit. The former No. 1 overall pick owns a 2.70 ERA, a 0.99 WHIP and 85 strikeouts against just 19 walks over 16 starts, numbers that would slot in near the top of almost any postseason rotation. He’s also set to become a free agent this winter on a one-year, $6.15 million deal, which makes him a pure rental for whoever lands him, but that’s exactly the profile a buyer like Houston should want at this point in the season.

The Astros have been connected to Mize in trade chatter dating back to early July, when many flagged him as a realistic target given Houston’s thin rotation depth beyond its top arms. Detroit, sitting comfortably atop the AL Central, has less urgency to deal him than other sellers might, but his impending free agency means the Tigers have real incentive to cash in now rather than risk losing him for nothing in the offseason. With no trade reported as imminent as of this weekend, Houston still has a window to get a deal across the finish line.

The Last-Minute Trade Offer

Houston’s farm system has intriguing young pieces it can use to make a real push for Mize without touching its major-league roster. Here’s the offer:

Astros receive:

• RHP Casey Mize

Tigers receive:

• RHP Bryce Mayer
• OF Anthony Huezo

This package gives Detroit two of Houston’s more promising development stories. Mayer, the Astros’ No. 5 prospect, has broken out at Double-A this season, posting a 2.61 ERA with 100 strikeouts in 69 innings after refining his changeup and pitch mix, a notable step up from a rough introduction to the level a year ago.

Huezo, a lean, projectable outfielder Houston signed for $397,500 as a 12th-round pick out of high school, followed a strong 2025 campaign with continued development in 2026, giving Detroit a long-term outfield prospect with real physical upside at just 20 years old.

Why This Trade Gets Done Before Monday

For Houston, surrendering a mid-tier pitching prospect and a projectable but unproven outfielder is a reasonable cost for a proven, win-now starter who instantly upgrades the middle of the rotation for a stretch run. The Astros have shown urgency about pitching all month, and Mize represents the kind of controllable-in-name-only rental who fills exactly the gap Houston’s rotation has needed since injuries piled up.

For Detroit, getting back two Top 15 organizational prospects for a pending free agent is smart asset management, especially with the Tigers firmly in playoff position and unlikely to be swayed by keeping Mize for two extra months of a division race they’re already positioned to win comfortably. If Houston’s front office wants to make one more aggressive call before the deadline closes, sending Mayer and Huezo to Detroit for Mize is the move that finally solves their rotation problem.
