The White Sox trump card so far this young season is their offensive weaponry, and manager Robin Ventura's crew has been dealing.

Alexei Ramirez provided the ninth-inning heroics Sunday with a dramatic two-run walk-off homer for a 4-3 victory over the Indians at rain-soaked U.S. Cellular Field.

"He has been swinging a hot bat, that's for sure," Ventura said. "In that situation, I don't know if it mattered what (reliever John Axford) threw, he was probably going to take a pretty good hack at it. He's been knocking in a lot of runs, a lot of big runs for us early."

Ramirez is hitting .420 with 12 RBIs during his 13-game hitting streak to start the season.

"Everybody knows me as an aggressive hitter," Ramirez said through an interpreter. "I am going to go looking for a good pitch to hit. And when I get it, I am going to swing at it. That's what happened. He just left me a pitch up there, and I was able to put a good swing on it."

The Sox had taken a 2-1 lead in the eighth inning on a solo homer by Marcus Semien. But Sox closer Matt Lindstrom ran into trouble in the ninth.

Michael Brantley reached first to lead off the inning when his hard grounder was botched by rookie first baseman Jose Abreu for an error.

Yan Gomes singled before David Murphy drove in the tying run with a base hit. Mike Aviles sacrificed the runners to second and third before Nick Swisher stepped to the plate with one out. Lindstrom unleashed a wild pitch, allowing the go-ahead run to score.

"Closing's tough, it's not easy for anybody," Ventura said. "Once you give them an extra out, for whatever reason, whether you're walking a guy or there's an error that happens, it becomes tough, especially in a one-run game."

In the bottom of the ninth, Jordan Danks drew a walk and stole second. After Alejandro De Aza popped out, Ramirez stepped in for the 47th game-ending homer in U.S. Cellular Field history and his third homer of the season.

"The way things have been going lately, no game's over just because we're down a run, especially going into the ninth," Danks said.
