The Oakland Athletics will open their 2019 season Thursday on first baseman Matt Olson's 25th birthday against the Los Angeles Angels, but Olson won't be able to celebrate on the diamond.
Per Mark Feinsand of MLB.com, the team announced Friday that Olson has undergone a "successful" hamate excision surgery on his right hand after injuring it Thursday against the Seattle Mariners in Tokyo. Olson's injury came on a foul tip.
Last season was Olson's first in the majors, and he played in all 162 games for the A's.
