9/7/2026, 2:20:38 AM
In-Game Incident
During the third inning of the Arizona Diamondbacks’ Sunday matchup against the Houston Astros, shortstop Geraldo Perdomo was struck on the helmet by a 93 mph line drive off the bat of teammate Ketel Marte. Perdomo had just singled to lead off the inning and was caught between first and second base when the ball ricocheted off his helmet. He fell to the ground, remained motionless for several minutes, and was eventually helped to his feet and walked off the field without assistance. He was ruled out on the play and did not return to defense.
Background & Context
Perdomo entered the 2026 season after a strong 2025 campaign in which he finished fourth in National League MVP voting with 20 home runs and 100 RBIs. Although his 2026 production has dipped, he remains a key contributor, posting a .252/.359/.366 slash line and a .725 OPS through 138 games. His defensive reliability at shortstop and speed on the bases have kept him among the team’s most available players, missing only five games all year.
Data & Statistics
- Line-drive speed: 93 mph (Marte) – reported by multiple outlets.
- Perdomo’s season stats (through 138 games): .252 batting average, .359 on-base percentage, .366 slugging, .725 OPS, 9 home runs, 48 RBIs.
- Recent hot stretch (August 28): .327 average, .827 OPS, 9 RBI over 28 contests.
- Game result: Diamondbacks defeated the Astros 3–2; Nolan Arenado hit a two-run homer shortly after Perdomo’s exit.
Official Statements & Responses
Team medical staff classified the injury as a head contusion. Manager Torey Lovullo confirmed that Perdomo has not entered the concussion protocol and is being observed, describing the situation as “dodging a bullet.” The Diamondbacks announced they will monitor Perdomo through the remainder of Sunday and into Monday, with the expectation that he could start the next game.
