"It's been going on for a while," Vogt said of the injury. "I wouldn't say there's any particularity, it's just my foot hurts. Just trying to get through it."
On Wednesday, Vogt started his first game of the year at designated hitter. A's manager Bob Melvin said Vogt has had the bone bruise before and aggravated it "a little while" ago.
"I think whenever I can DH him or something along those lines, hopefully it can get that much better," said Melvin. "Those things don't go away very quickly, and we certainly don't want to DL him, and he doesn't want to go on the disabled list."
Vogt has been trying various insoles and orthotics to ease the pain, and while Melvin hopes he can eventually return to catching, for now he would only end up behind the plate in an emergency situation.
The left-handed hitter has not caught since July 7.
