Manning (biceps) has resumed throwing off flat ground from 90 feet at the Tigers' spring training facility in Lakeland, Fla., Evan Petzold of the Detroit Free Press reports.

EDGE Analysis

The 24-year-old has already spent more than two months on the 10-day injured list, and he may have a tough time making it back before the All-Star break even though he hasn't been shut down from throwing. He still has to increase his long-toss distance before advancing to mound work and then facing hitters before the Tigers send him back out on a rehab assignment. After previously making four rehab starts with Triple-A Toledo in May, Manning was pulled off the assignment while he was pitching through biceps tendinitis. He was initially placed on the IL due to right shoulder inflammation.
