Former All-Star reliever Joel Hanrahan, attemtping a return from Tommy John surgery, should expect a big crowd of scouts when he throws for teams Thursday in Tampa.

The Mets, Yankees, Royals, Athletics, Red Sox and Dodgers are among a decent-sized group of teams that has lost their closer or main set-up man because of injury or poor performance, and all could easily have interest in Hanrahan.

The Cardinals, Indians, Rays, Rockies, Rangers and Angels are among a long list of other teams with possible interest in Hanrahan, a two-time All-Star who had surgery last May 16 and appears ready to come back strong.

Mets closer Bobby Parnell is out for the year with his own Tommy John surgery, while the Yankees and Red Sox are temporarily without closers, David Robertson and Koji Uehara. Boston would be an interesting spot for Hanrahan, as he had just begun his Red Sox career when he injured his elbow. In Boston he was ultimately replaced by Uehara, who went on to pitch brilliantly and helped lead Boston to a World Series title but is sidelined now because of a shoulder concern.

The Royals lost setup man Luke Hochevar for the year, the Dodgers are without setup man Brian Wilson temporarily while the Athletics demoted closer Jim Johnson.

Ryan Madson, also returning from injury, and Kevin Gregg are among other top free agent relievers remaining.
