The Oakland A’s optioned catcher Bruce Maxwell to Triple-A on Thursday, the team announced. The move makes room for the promotion of pitcher Cesar Valdez, who will start the day’s game against the Mariners in place of the injured Kendall Graveman. To make room for Valdez on the 40-man roster, injured shortstop Marcus Semien was transferred to the 60-day disabled list.
Maxwell was recalled on Monday when Graveman went on the DL, but apparently it was just a quick stop for a couple days while there was a free spot open on the squad.
