ST. PETERSBURG, Fla. -- Jonny Gomes wanted to make something clear: He doesn't have it out for Tampa Bay.
Gomes got a huge hit against his former team Saturday night, a go-ahead homer in the 12th inning that sent the Oakland Athletics to a 4-3 victory over the Rays.
Gomes, who spent six seasons with Tampa Bay from 2003-08, hit his fifth home run of the season off reliever Joel Peralta (0-1) to stop the Rays' six-game winning streak.
"At this point, I've got a lot of ex-teams," Gomes said, "and I've got nothing but respect for that team over there. This isn't, rub it in Tampa's face, or it's awesome because it's against my old team. It's just good to get a win against the best team in baseball right now."
"I know he plays hard. He goes after every ball hard, so that doesn't surprise me at all," Pena said. "I was amazed at the catch and I think all of us were shocked when he came up with that ball."
Pena, Ben Zobrist and Elliot Johnson all homered as Tampa Bay rallied to bail out Jeremy Hellickson after an ineffective start. But the Rays fell to 13-2 at home and failed in their bid to become the first major league team to reach 20 wins this season.
"The former Rays thing doesn't really come into play, but Gomes has come up big for us this year," A's manager Bob Melvin said. "But if you're giving out a player of the game, then it's him because he didn't even start the game, but he made the two biggest plays with the catch and then the homer."
The A's worked long at-bats to run up Hellickson's pitch count and chase last year's AL Rookie of the Year after 3 2/3 innings.
Hellickson threw 52 pitches through two innings and finished with 102 in the shortest outing of his young career. He gave up three runs, two earned, on five hits and three walks.
"Sometimes you can be effective not scoring runs on a guy," Melvin said. "We didn't cash in as often as we would have liked to with a guy that threw that many pitches in a short time, but it got him out of the game."
"Bullpens did the job," Reddick said. "That's how you win extra-inning ballgames -- your bullpen has to put up zeros."
Tampa Bay had a chance to win in the 11th when Sean Rodriguez reached third with one out after a leadoff double that dropped between three players in shallow right field. Johnson, however, struck out when he fouled off a suicide squeeze attempt with two strikes and Desmond Jennings flied out.
Johnson homered in the third, Zobrist in the fourth and Pena in the fifth to tie the game. All three came from left-handed hitters -- manager Joe Maddon intentionally put six left-handed bats in Tampa Bay's lineup.
Oakland starter Bartolo Colon had held left-handed batters to a .198 average coming in, but he ended up throwing 83 pitches over five innings and giving up eight hits.
"We had a lot of good at-bats," Maddon said. "We hit some balls hard without any luck."
Reddick hit his fifth homer in the first and Cliff Pennington scored in the third after reaching on an error by Zobrist. Kila Ka'aihue drove in Pennington with a single, and Reddick added an RBI single in the fourth.
"It felt like no team wanted to execute enough to win the game," Melvin said. "Each team had their chances, but didn't take them. This game just had a crazy feel to it."
