June 10, 2025 12:27 AM : Martinez left Monday's game against the Mariners with an undisclosed injury, Jack Sommers of SI.com reports.
Analysis: Martinez was one out away from recording his sixth save of the season, but he made a motion for the trainer after throwing a 97 mph sinker to Donovan Solano. Martinez is presumably headed for further evaluation to determine the severity of his injury. Jeff Brigham was deployed in Martinez's stead.
