The Athletics most likely won't need a fifth starter before Sonny Gray is activated. Here are the options for who the A's could call up in the meantime.
The Athletics optioned starting pitcher Eric Surkamp to Triple-A Nashville on Thursday. As this is an off day, no corresponding move needs to be announced until Friday.
The move commits the A's to a four-man rotation that includes Rich Hill starting on Saturday. There had been some concern about Hill after he sustained a minor groin strain in his last start on Sunday, but he came through a bullpen session fine and the A's elected to just give him an extra day of rest afforded by Thursday's off day.
