NEW YORK -- David Phelps was supposed to be on the mound tonight at Citi Field. Instead, he landed on the 15-day disabled list with a left oblique strain. The Marlins called up right-hander Jake Esch to take Phelps' place in what will mark his major league debut.
Phelps said he sustained the injury while taking batting practice on Tuesday.
"I actually did it in the batting cage yesterday," Phelps said. "First swing. I just felt something, shut it down. My initial reaction and our initial thought was I would maybe miss one start."
The Marlins waited to see how Phelps felt when he woke up this morning before making a decision.
"Woke up, it was still stiff," Phelps said. "So they decided to put me on the DL."
Phelps said his arm his fine and that he expects to resume throwing in about four days. If all goes well, he'll miss no more than two starts.
"The silver lining would have been if it had happened on Sept. 1 (when rosters expand) and you wouldn't have had to worry about a DL stint," Phelps said. "But it's Aug. 31, so we've got to make a roster move. My arm's perfectly healthy."
Esch is a former 11th-round pick for the Marlins and has gone 12-10 with a 4.31 ERA this season for Double A Jacksonville and Triple A New Orleans.
