Instead, Parnell will have Tommy John surgery and end his 2014 season. The decision came on Sunday night after it had been diagnosed that the closer would be about ’50-50′ for the surgery. Parnell had been pitching with a partially torn MCL and after his 2014 debut last week, was shut down due to the injury.

Parnell had been thought ready to go for the season after having a decent spring. He established himself as the Mets closer towards the end of last season when Frank Francisco went down with an injury, but neck issues ended his season. He apparently suffered the MCL tear during Spring Training but had been trying to pitch through it.

In Parnell’s stead, former Tigers’ closer Jose Valverde will be the closer for the Mets and fellow free agent acquisition Kyle Farnsworth will step into the setup role.
