Carlos Pena hit a tying solo homer off All-Star closer Joakim Soria in the ninth, but it wasn't enough for the first-place Rays, who finished a seven-game homestand at 6-1.

Billy Butler reached second to start the 10th on a throwing error by Rays third baseman Evan Longoria. Pinch runner Esteban German advanced to third on Mark Teahen's grounder. After Dan Wheeler (2-4) intentionally walked Ross Gload, Buck lined his fourth homer of the season down the left-field line. Two pitches later, Aviles homered to make it 7-3.

Soria (1-1) blew his second save in 25 chances. The right-hander also allowed Eric Hinske's solo homer in the bottom of the 10th.

Tampa Bay, with the major's best record at 55-33, lost for the second time in the last 13 games.
