Tim Lincecum to regain velocity upon comeback?

Whether or not Lincecum—a soon-to-be free agent—even returns to San Francisco remains to be seen, but if the latest report from Heyman can be believed, the Giants will be one of many teams lining up for his services.

In a Sept. 4 write-up, Heyman quoted the surgeon as saying Timmy’s procedure would “help tremendously” in helping the two-time Cy Young Award winner regaining velocity and control. He didn’t go into any more specifics at that time, but in a Sept. 18 notes piece, Heyman floated “92-94 mph” as a predicted range for his resurrected heater.

That, of course, depends on the relatively new surgery following through (no pun intended), which we will only know once Lincecum completes his rehab and moves onto live workouts. With the history of degenerative hip conditions in baseball, it’s hard to be as optimistic as the man behind the knife.
