The Marlins have placed Giancarlo Stanton and Joe Mahoney on the disabled list, each with right hamstring injuries, and are calling up outfielder Marcell Ozuna from Double A Jacksonville and pitcher Brad Hand from Triple A New Orleans.
Stanton is scheduled to undergo a MRI on Tuesday.
"We'll find out more tomorrow," Stanton said. "But anytime you go down, it's not good."
Stanton suffered the injury in the 10th inning while trying to beat out a nubber hit in front of the plate. He grimaced after crossing the bag at first, reached back for his leg, hopped twice, and fell to the ground. He said he heard a "pop," just as first baseman Casey Kotchman did when he suffered a hamstring injury the second game of the season. Kotchman remains on the DL.
"Not good," said Larry Beinfest, Marlins president of baseball operations, standing outside the clubhouse following Monday's morning, which ended early Tuesday morning. "He's hurting. It grabbed him pretty good."
Manager Mike Redmond said Ozuna would likely take Stanton's place in right field. Ozuna, 22, is one of the organization's top prospects, and he's off to a hot start at Jacksonville, where he's hitting .333 with 5 home runs and 15 RBI in only 42 at bats.
Because the bullpen was used hard (11 innings) Monday, Hand was brought up as insurance. Hand was scheduled to start Tuesday for New Orleans.
"Obviously a big blow losing Stanton," Redmond said. "We're enjoying this win tonight. But at the same time tomorrow the reality will set in that he's not in the lineup anymore. But Ozuna's an exciting player and hopefully he'll come up and provide a spark."
-- In terms of innings, Monday's 15-inning game was one of the 10 longest in franchise history. Elapsed time of the game was 5:31. The longest game was the Marlins' 20-inning affair against St. Louis in 2003, which lasted 6:07.
