HOUSTON, TEXAS — The 2025 Houston Astros have navigated one of the most injury-plagued seasons in recent memory, a challenge that has tested the team’s depth and resilience. According to analytics from FanGraphs’ Dan Szymborski, the Astros have suffered the most significant potential loss in Wins Above Replacement (WAR) due to injuries of any team in Major League Baseball. WAR is a comprehensive statistic that measures a player’s total value to their team by calculating how many more wins they contribute compared to a replacement-level player. The Astros’ projected loss stands at a staggering 17.6 WAR, topping the list ahead of other teams like the Baltimore Orioles and Los Angeles Dodgers.
The injury bug has not spared any part of the roster, hitting key players at every position. At various points in the season, the team’s three best hitters—Jeremy Peña, Yordan Alvarez, and Isaac Paredes—were all on the Injured List simultaneously. Alvarez, in particular, has been the most significant individual loss, with his health issues causing a projected loss of 3.3 WAR. His latest setback, a severe ankle sprain suffered while scoring, comes after he missed 100 games earlier in the season with a lingering hand injury.
The pitching staff has also been hit hard. The starting rotation has been decimated, with only Hunter Brown and Framber Valdez still active as the season nears its end. Key pitchers like Ronel Blanco, Spencer Arrighetti, Cristian Javier, Lance McCullers Jr., and J.P. France have all spent time on the Injured List, contributing to the team’s league-leading injury count. The bullpen has not been immune either, with All-Star closer Josh Hader potentially missing the entire postseason due to a shoulder strain.
Despite the litany of injuries, the Astros have managed to stay competitive, a testament to their depth and the contributions of players from the fringes of the roster and minor league system. While the team has been forced to rely on many players who were not expected to be regulars, this adversity has also been a proving ground, as several of these players have stepped up in key moments. The team’s ability to remain competitive despite the onslaught of injuries is a testament to its depth, and a hopeful sign as they continue their push for a playoff spot.
