Free agent lefty Cliff Lee is drawing interest from no fewer than fifteen teams around the league, Jon Heyman of CBSSports.com reports on Twitter. The long-time ace is reportedly preparing to return to the mound in 2016.

It’s certainly not surprising to hear that so many organizations are looking into the southpaw. While he’s 37 and will be looking to make his way back from a flexor tendon tear without surgery, Lee offers unmatched upside among the bounceback candidates on the free agent market.

It’s far from clear, of course, whether teams are willing at present to commit big dollars to Lee. Certainly, they’ll want to learn more about his progress and prognosis. But the report does make clear that there’ll be no shortage of teams lined up to pursue Lee if he shows promise of returning to the form that made him one of the game’s best pitchers well into his mid-30s.
