Jon Lester has known about the bone chip in his pitching elbow since a personal MRI in 2014. The Chicago Cubs knew about it before signing him to a $155 million dollar deal. The feeling was that Lester’s MRI compared “favorably” with other pitcher’s MRI’s the team had viewed in recent years. But many can’t help but ask if it’s the reason he might have struggled last season.
“It’s kind of one of those deals if it’s not bothering you, don’t mess with it,” Lester said, according to the Sun-Times. “You start getting cut on and doing rehab, and that’s when maybe they’re in there, taking that bone chip out, and it puts more stress on something else.
