UPDATE: The Rays have confirmed that Longoria will be out 6-8 weeks with a partial tear of his hamstring.

The Rays’ Evan Longoria left last night’s game against the Mariners with what looked like a knee injury, but Marc Topkin of the Tampa Bay Times is hearing it may actually be a hamstring injury, that would keep the three-time All-Star out of the lineup for 6-8 weeks.

Longoria was injured in the third inning of last night’s ball game, after sliding awkwardly into the bag at second on a stolen base attempt.  Longoria walked off the field on his own, and after the game, manager Joe Maddon described the injury as a “day-to-day gig right now.”

This season, Longoria has posted a slash line of .329/.433/.561, all above his career line of  .276/.362/.516. He posted a 6.1 fWAR in 2011, and had a projected 7.9 fWAR for 2012.

Elliot Johnson, who took over for Longoria last night, would likely see more playing time at third with Longoria out, with Sean Rodriguez and Jeff Keppinger possibly playing the “hot corner” for Joe Maddon.
