OAKLAND -- Oakland's Seth Smith was unavailable for a second straight game Wednesday because of an eye astigmatism. Smith wasn't even at O.co Coliseum, since he was seeing doctors, but was expected to board the team's charter flight to Baltimore come Thursday.
"I'm not sure how long it's been bothering him," said manager Bob Melvin. "Hopefully we have him Friday in Baltimore."
Smith, who typically starts against only right-handers as the designated hitter, hasn't been in the lineup since Saturday. He's batting .241 with six home runs and 33 RBIs on the season.
Alberto Callaspo, who has a pair of three-hit games in his last three contests, started at DH on Wednesday.
