Flushing, NY (SportsNetwork.com) - The New York Mets placed closer Bobby Parnell on the 15-day disabled list and second baseman Daniel Murphy on the paternity list on Wednesday.

Parnell was diagnosed with a a partially torn medial collateral ligament in his right elbow on Tuesday and he could need surgery. Murphy, meanwhile, missed the Mets opener on Monday to be with his wife, Victoria, who gave birth to the couple's first child, Noah.

The Mets said Tuesday that Parnell complained of tightness in his elbow following Monday's game against Washington. He underwent an MRI exam, which revealed the injury. He received a Platelet Rich Plasma injection, will rest for two weeks and will then begin a throwing program, which will determine if surgery is necessary.

The 29-year-old right-hander blew a save Monday when he yielded the tying run in the ninth inning of what eventually finished as a 9-7 Washington win in 10 innings.

Parnell was coming off the best season of his career in 2013 when he notched 22 saves in 26 chances while posting a 2.16 ERA in 49 games. He missed the last two months of the season with a herniated disc in his neck that required surgery last September.

The Mets selected the contract of pitcher Kyle Farnsworth and recalled infielder Wilmer Flores from Triple-A Las Vegas to fill out the 25-man roster. The club also outrighted pitcher Ryan Reid to make room on the 40-man roster for Farnsworth.

Flores hit .238 with two homers and nine RBI in 14 spring training games this season. He was optioned to Triple-A Las Vegas late in camp to work more on becoming a shortstop, a position the Mets are willing to transfer him to if Ruben Tejada continues with his struggles from last season.

Flores hit .211 with one homer and 13 RBI in 27 games with the Mets last season.

Farnsworth was signed to a minor-league contract in the offseason, but was released and then re-signed by the club late in camp after not making the 25- man big league roster.

In nine spring training games this season, the right-hander allowed six runs on 12 hits with four walks and six strikeouts in 10 innings. In 48 games last season with the Pirates and Rays, he went 3-1 with a 4.70 ERA in 48 appearances.
