Red Sox pitcher Josh Beckett expressed frustration over his lower-back, which has forced him to slow down his rehab process.
Beckett said he needs to be 100 percent before he picks up a baseball again.
He was scheduled to come off the 15-day disabled list on June 3, but that's unlikely given his recent setback.
"It's Groundhog Day right now," Beckett said Sunday. "Just trying to get things better."
