UPDATE: Lester has been placed on the disabled list with what has been described as “shoulder fatigue.”
9:55 AM: Jon Lester had a terrible outing yesterday, allowing nine runs — seven earned — and leaving the game before he could complete two innings.Lester entered the afternoon with a 3.99 ERA. He exited with a 4.37 ERA. Later the Cubs said that Lester was suffering from left lat tightness.
The Cubs are now saying that Lester will miss 1-2 starts. They are sending him to see Dr. Stephen Gryzlo for a more in-depth exam, and it’s possible Gryzlo will determine the injury is more serious, but at the moment the assessment seems cautiously optimistic.
Mike Montgomery will fill in for Lester for the time being.
