Kiermaier was removed from the game as he held his left wrist after he slid into second base on a steal attempt in the top of the second inning at the Oakland Coliseum.
Injuries have been a persistent theme throughout Kiermaier's career. He made 150-plus appearances just once in his first six seasons upon becoming a regular for Tampa Bay, missing an average of almost 49 games per year.
The 31-year-old was absent for 11 of the Rays' 60 games during the shortened 2020 campaign. He largely struggled at the plate, finishing with a .683 OPS. He continued to be an elite fielder, though, even if he wasn't a Gold Glove finalist at his position.
This season has seen Kiermaier continue to struggle at the plate. He was hitting .217/.289/.290 with no homers and five RBI in 22 games entering Saturday.
With Kiermaier unavailable, Brett Phillips took over in center field and Manuel Margot moved into right field for the Rays.
