Ailing 3B Evan Longoria will not take just one step toward his recovery from a partially torn left hamstring today, he'll take several. And he'll take them all at a pretty good clip, too.

Plans call for Longoria to give his sore hamstring its biggest test since he suffered the injury on May 1 when he runs at Marlins Park under the supervision of the Rays medical staff and likely manager Joe Maddon.

"That will tell us a lot,'' said Maddon, who isn't quite ready to predict when Longoria will return to action. "I don't have an absolute finish line with him. A lot of it is going to be based on how he feels.''

Longoria's running stint comes at a time when the Rays are starting to regain some of their wounded warriors. OF Desmond Jennings returned earlier this week from a sore knee and RHP Kyle Farnsworth is on the brink of a return as well.

Farnsworth has been out since April 6 with a right elbow strain, but the Rays announced Friday that Farnsworth is slated to begin a rehab assignment Monday with Class-A Charlotte.
