OAKLAND -- An MRI has revealed a slight tear in Kyle Blanks' left calf, meaning he will be on the disabled list longer than originally expected.
"He's going to be a while," manager Bob Melvin said Friday. "There is a little bit more of a strain going on in the calf, a slight tear. He's going to be considerably longer than we were originally thinking."
Blanks had been playing with a left calf strain, but he was forced to go on the 15-day DL when he aggravated it during a June 22 game against the Red Sox. He had recently begun taking swings, but in light of the MRI results, Melvin said there is no timetable for his return.
Since being traded to the A's from San Diego on May 15, Blanks is 15-for-45 (.333) with two home runs and a .446 on-base percentage. He has appeared in 20 games at first base in addition to a couple of corner outfield appearances.
