Athletics utility player Zack Gelof has filed a 16-page lawsuit against the Detroit Tigers, Ilitch Holdings and the Detroit-Wayne County Stadium Authority, alleging negligence after he suffered a deep knee laceration sliding into an exposed metal fence at Comerica Park.
The complaint, filed Monday in Wayne County Circuit Court, stems from a July 9 game in which Gelof, then 26, was playing left field in the third inning of a 4-1 Athletics loss. Tigers infielder Zach McKinstry lofted a foul ball down the left-field line. Gelof made a long run, slid and recorded the out — then his right knee slammed into a rigid, inadequately padded section of fencing that jutted into or alongside the field of play.
The impact tore his uniform and produced a deep cut beneath the right kneecap that narrowly missed the patellar tendon. Athletics manager Mark Kotsay said after the game the laceration was “deep” and that an MRI would follow; Gelof left the field in obvious pain and did not return. He spent roughly 30 days on the injured list, beginning a rehab assignment in early August and rejoining the club on Aug. 10.
The lawsuit describes the fence as “rigid, sharp, [and] inadequately protected” in an area where players routinely run and slide for foul balls. It accuses the defendants of failing to inspect the hazard, provide sufficient padding or clearance, warn players, or redesign the structure. The complaint notes that padding was added to the same section shortly after Gelof’s injury — a fact the suit treats as evidence the risk was both known and easily remedied. It also cites Tigers left fielder Riley Greene, who told reporters after the game that the metal wall “can be quite unforgiving during a hard slide.”
Attorney Jon Marko, who filed the case with Gasper Stare of Marko Law, called the injury preventable.
“This injury could have easily [been] prevented through the most basic and inexpensive design,” Marko said. “It doesn’t take a stadium design expert to realize that sharp metal fencing in an area where players are required to slide and play around is a recipe for disaster like the one that occurred here. All they had to do was put cheap padding up like they did after Zack was injured and this entire incident could have been avoided. My son’s little league diamond is safer.”
Gelof, coming off a career season (.256, 22 home runs, 55 RBIs and 3.5 WAR in 111 games), made $820,000 in 2026 and is eligible for salary arbitration for the first time this offseason. The suit seeks unspecified compensatory damages for medical expenses, lost wages, diminished future earnings, pain and suffering, and emotional distress. Claims include premises liability, negligence, negligent design and a public-building exception against the stadium authority under Michigan law.
The Tigers issued a brief statement Tuesday: “We are aware of the lawsuit and do not comment on pending litigation.”
The case has already revived a familiar debate around ballpark design: how much risk visiting players should reasonably accept on another club’s field, and whether padding that appeared after an injury should have been there beforehand. Gelof’s lawyers argue the answer is straightforward. The defendants now have the chance to answer in court.
