DOCTOR VISIT: Right-hander Justin Verlander, who left Double-A Erie's game in the fourth inning Tuesday night with tightness in his pitching shoulder, was found to have a minor inflammation in the back of his shoulder caused by fatigue. There was no structural damage.
He was diagnosed after flying to Detroit on Wednesday to be examined by team physician Dr. Kyle Anderson.
Verlander was told to rest for 10-14 days before he resumes throwing.
Verlander, who pitched 105 innings last year in college at Old Dominion, has thrown 130 this season among Class A Lakeland, Erie and two starts with the Tigers. He'll probably total 160-165 innings before the Tigers shut him down.
"Jon Matlack is monitoring Verlander carefully," Tigers pitching coach Bob Cluck said, referring to the club's minor league pitching instructor. "Nothing is going to be left to chance."
Doesn't sound too major, but I don't want to see them push him too far. Fortunately, it sounds like they will take the cautious approach with him for the rest of the season.
