Miami Marlins manager Mike Redmond didn't spend much time trying to figure out how one suffers an elbow bruise making a throw during batting practice.

"At this point, I just shake my head and move on," Redmond said. "There's not much you can do. We've had a bunch of guys get banged up and you just keep going, keep moving."

The latest in that bunch is shortstop Adeiny Hechavarria, whom the Marlins placed on the 15-day disabled list Thursday. Redmond scratched Hechavarria from Wednesday's lineup against the Nationals. After the 6-1 loss, he revealed Hechavarria experienced right elbow discomfort and came off the field.

"It's not a ligament or anything like that," said Redmond, relaying the results of an MRI. "He just tweaked it making a throw. … It'll just be a matter of taking a break and getting some rest."

Earlier Wednesday, the Marlins activated first baseman Joe Mahoney (oblique). Thursday, they also got back Giancarlo Stanton, who missed the last six games with left shoulder soreness.

Before Wednesday, Hechavarria has started each of the club's first 14 games at shortstop and hit .184/.231/.286 through 49 at-bats. His three RBI on the season came on one swing Tuesday, when he homered off Dan Haren in the second of two Marlins' wins during the nine-game homestand.

Hechavarria will take some time off before beginning a throwing progression program. He cannot return to action any earlier than May 2.
