We’re nearly a week into February, and there is still room for the Oakland A’s to make another addition to their pitching staff if they want to. The starting rotation has plenty of candidates but it would be fair to say there are only two guaranteed members in Mike Fiers and Marco Estrada, with everyone else representing some sort of injury bounce-back, or untested prospect, or swingman who hasn’t fully proven himself.
There has been some minor movement on the staff lately, even outside of the signing of Estrada. Parker Bridwell now provides some non-roster rotation depth, and Jerry Blevins does the same for the bullpen.
