CHICAGO (AP) The Chicago Cubs got an encouraging report on Jon Lester before placing the ace left-hander on the 10-day disabled list on Friday.
Lester was examined by team physician Dr. Stephen Gryzlo after he left Chicago's 13-10 loss to Cincinnati on Thursday in the second inning. He was diagnosed with tightness in his left lat and general shoulder fatigue, but his shoulder and side were deemed structurally sound.
"I think the big thing is just the overall performance was not there," Lester said. "This is something that we tried to manage and get through. It just got to a point where you're doing a disservice to your team by going out there and not being able to perform.
