COLUMBIA -- South Carolina's baseball team continues to lose players -- and win games.

After a weekend sweep of Auburn, the injury-stung Gamecocks (35-8, 17-4) leapt to No. 1 in the Collegiate Baseball poll. They remained No. 2 in the recognized Baseball America poll, still trailing Virginia despite a Cavaliers loss to Boston College over the weekend.

South Carolina is mathematically tied with Florida and Vanderbilt for the SEC lead, but it holds the head-to-head advantage over both teams based on series wins.

"We're trying to keep enough guys on the field," USC coach Ray Tanner said Monday on Columbia's 107.5 "The Game." "We've been finding a way to win. It's a great challenge for us right now. You can't say enough about our players right now."

The team's beleaguered outfield continues, quite literally, to require a daily medical watch.

On Monday, sophomore Evan Marzilli underwent an ablation procedure to correct an intermittent rapid heartbeat.

Ablation, the Mayo Clinic website says, is a procedure that "works by scarring or destroying tissue that blocks the electrical signal that travels through your heart to make it beat. By clearing the signal pathway of the abnormal tissue, your heartbeat may beat normally again."

A release from the school said Marzilli, hitting .260 with two home runs and 19 RBIs in 39 games, was "resting comfortably and is not anticipating any long-term effects."

Marzilli is questionable for Wednesday's game at Wofford, but he is expected to travel with the team this weekend to Ole Miss.

"He feels good," Tanner said. "We think he'll be OK for the weekend. That's some good news for us. If we keep Marzilli out there, we've still got a pretty good outfield."

Marzilli missed last week after an initial scare with his heart rate, but he was cleared in time for the Auburn series. He went 3 for 10 with two RBIs and five runs scored in the team's three victories. Marzilli started all weekend in center field, in the place of injured All-American Jackie Bradley Jr. Bradley went down with a left wrist injury April 24 at Mississippi State.

Tanner says it's a "wait-and-see situation," but Bradley continues to insist on his Twitter account that he will return in the next month or so. He seemed to take exception Sunday night with a newspaper column that asserted his college career was done.

Tanner said Adam Matthews (hamstring) has made "a lot of progress." But then he added the junior is not close to playing because he cannot run in the outfield. Tanner said Matthews might be able to pinch hit in two or three weeks.

The newest injury is freshman DeSean Anderson, who started Sunday in left field and injured his hamstring running to first base during the game. Tanner called Anderson "day to day," and said his status will not be known until later in the week.

With the injuries, pitcher Steven Neff will again be called into action as an outfielder. And Robert Beary will have to be versatile, bouncing between catcher and the outfield.
