August 21 Roster Update: A Quiet Friday for Diamond Dynasty
The August 21, 2026 MLB The Show 26 roster update is a transactional cleanup—13 new cards and a handful of small bumps, but nothing that'll shake up your squad or the Stub market. SDS handed out seven upgrades across mostly low-tier Commons, with two players crossing into Bronze territory.
The Two Bronze Promotions
Tanner Gordon (Rockies) jumped from 61 to 66 overall, and Robert Stock (Mets) climbed 64 to 68—both now Bronze. These Common→Bronze moves reset each card's quick-sell floor and typically trigger short-term price spikes as collectors and completionists update their binders. Neither card carries Diamond Dynasty relevance beyond collection value, but if you scooped them cheap earlier in the week using ShowZone's free Roster Update Predictor (/market/roster-update-predictor), you've got a small flip window before supply catches up.
The Rest of the Upgrades
The remaining five bumps stayed in Common range: Cameron Weston (Orioles, 56→62), Miguel Ullola and Ethan Pecko (Astros, both to 62), José Urquidy (White Sox, 57→62), and Troy Watson (Mariners, 55→60). All transactional call-ups with negligible market impact.
Thirteen new cards also entered the database—mostly low-60s Commons like Matt Wilkinson (Giants SP, 63) and Carson Roccaforte (Royals CF, 63)—rounding out live rosters but offering zero lineup upside.
Save your Stubs. The next big update cycle awaits.
