NEW YORK -- Since being recalled from Triple-A Las Vegas in June, Josh Edgin emerged as a reliable reliever for Terry Collins and the Mets. On Friday, the lefty learned his season would be interrupted for a considerable amount of time.
After Edgin underwent an MRI on Friday morning, it was revealed he had a stress fracture in the eighth rib on his left side. The Mets placed Edgin on the 15-day disabled list and called up Pedro Feliciano, who pitched for the club from 2002 to '10, to fill Edgin's spot on the roster.
There's no definitive timetable for Edgin's return.
"They don't know exactly how long. I've heard four weeks, I've heard six weeks," Edgin said. "You don't know exactly how long it's going to take for a bone to heal."
Edgin said he first felt pain when the Mets were in Pittsburgh from July 12-14, but figured it was just a normal ache. He also said it wasn't an issue when he was on the mound in subsequent games, but rather once the adrenaline wore off after games. It would be especially painful in the mornings before he loosened up.
But since he was pitching well, Edgin, who's allowed only two runs in 23 outings since joining the Mets on June 10, wanted to pitch through it.
After pitching in Miami on July 29, though, he couldn't do that any longer. It hurt more than it normally did, and Edgin decided to go through with the MRI that showed the fracture on Friday. Edgin said he doesn't know what caused it.
"It kind of caught me off guard this morning," Edgin said. "I'm kind of thinking, 'All right, let's just take a couple days and get it healed back up.' I found out otherwise."
Edgin said it's frustrating to go on the DL since he had been giving the Mets solid performances out of the bullpen. Since being called back up to the Major Leagues in June, Edgin was 1-1 with a 3.77 ERA in 34 games.
Meanwhile Feliciano, who hasn't pitched in the big leagues since 2010, will take Edgin's spot in the bullpen. With Double-A Binghamton, Feliciano had a 1.26 ERA in 14 games before being promoted to Las Vegas on July 23.
Feliciano had only thrown two scoreless innings in Triple-A.
He signed a two-year contract with the Yankees in 2011, but persistent shoulder problems never allowed him to pitch in the Major Leagues.
Feliciano led the National League in appearances from 2008-10 with 266.
Pain in the neck: Stiffness keeps Parnell out
NEW YORK -- The Mets are without their closer as Bobby Parnell continues to deal with a stiff neck.
Parnell first experienced the pain during the Mets' road trip in Miami this week, but the problem hasn't subsided. Mets manager Terry Collins said Parnell has seen the doctor and received medication to "quiet the area down," but Collins doesn't expect to have Parnell until Sunday at the earliest.
But Collins also said Parnell won't be re-examined again until Monday.
In the meantime, David Aardsma, who has 69 career saves, will close out games for New York. LaTroy Hawkins will continue to pitch the eighth inning, Collins said.
"We've got David Aardsma who has closed in the past," Collins said. "So we'll probably use him right now, leave Hawk where he is. He's done such a great job in that eighth inning."
Parnell last pitched on Tuesday, closing out the Mets' 4-2 win over the Marlins to earn his 22nd save this season.
Collins shuffles Mets' lineup in search of spark
NEW YORK -- Searching for a way to get his lineup to produce some runs, Mets manager Terry Collins shuffled his lineup for Friday's game against Kansas City.
Collins moved second baseman Daniel Murphy down to the fifth spot, and first baseman Ike Davis down to seventh. Center fielder Juan Lagares hit second, where Murphy had been hitting.
Davis is hitting only .224 with one home run since being recalled from Triple-A Las Vegas, where he was sent to fix his swing and correct his issues at the plate, on July 5.
"I respect the fact that he's working on some things," Collins said. "He's trying to see pitches longer, he's trying to get a better ball to hit. Right now we need to drive in some runs."
The Mets have scored only two runs in their last two games.
Collins is hoping moving Murphy to the heart of the order helps turn that around. Murphy has been on a tear at the plate, hitting .337 with six doubles and 19 RBIs in his last 24 games. He also has at least one hit in 20 of those games.
"Murph is swinging good," Collins said. "I always thought no matter what, if it was a different situation where Ike was out, Dan Murphy's a perfect guy to hit down in that spot."
Lagares has also been producing, hitting .404 since July 9.
"We've got four guys in a row with 50 RBIs," Collins said of the middle of his order. "I kind of liked the way that looked."
• Terry Collins said lefty Jon Niese will throw a bullpen session at Citi Field on Sunday, and will then make another rehab start. Niese, who's been on the disabled list since June 21 with a partial tear of his rotator cuff, pitched four scoreless innings for Class A St. Lucie on Thursday night. He allowed two hits with one walk and four strikeouts.
