Mets' Broken Fibula Adds to Injury Crisis as Subway Series Odds Tumble

Clay Holmes, the Mets' Opening Day starter, suffered a broken right fibula when he was struck by a Spencer Jones comebacker in the fourth inning of Friday's 5-2 loss to the Yankees. Postgame X-rays confirmed the break, and manager Carlos Mendoza said Holmes is "going to be down for a long time." The injury immediately reshaped the Subway Series market on Polymarket, where the Mets' win probability for Saturday night's game dropped 15 percentage points to 38.5% on $879,000 in volume.

Holmes, who signed with the Mets in December 2024 after three-plus seasons with the Yankees, was 4-4 with a 2.39 ERA this season. His loss is the latest blow to a Mets roster that entered the year with World Series aspirations and now sits in last place in the National League East at 18-26. Seven members of the Opening Day roster are on the injured list, including four Opening Day starters: catcher Francisco Alvarez (right knee), shortstop Francisco Lindor (left quad), first baseman Jorge Polanco (Achilles) and center fielder Luis Robert Jr. (back). All are out indefinitely.

The Yankees are not without their own injury concerns. Left-hander Max Fried was placed on the 15-day injured list Friday with a left elbow bone bruise after an MRI confirmed his ulnar collateral ligament is intact. Fried said the timeline is "ambiguous," but the Yankees (28-17) have the second-best record in the American League and can afford patience. Right-hander Carlos Rodon, making his second start of the season after arthroscopic elbow surgery last October, starts Saturday opposite Mets opener Huascar Brazoban and bulk reliever David Peterson.

The market's sharp move reflects both the Holmes injury and the broader disparity between the two teams' current health and form. The Yankees have the luxury of depth: Cam Schlittler leads the majors with a 1.35 ERA, and former Cy Young winner Gerrit Cole is nearing the end of a rehab stint after Tommy John surgery. The Mets, by contrast, are scrambling for reliable innings and have lost six of their last 10 games.

With the market closing May 23, the implied 38.5% probability gives the Mets roughly a 1-in-2.6 chance of winning Saturday night. Traders will watch how Brazoban and Peterson handle a Yankees lineup that scored five runs in each of the last two games, and whether the Mets' depleted bullpen can hold a lead if they manage to grab one early.
