Mets backup catcher Anthony Recker could laugh about it afterward.
With the Mets trailing 11-0 in the eighth inning and manager Terry Collins having already burned four relievers, Recker pitched the ninth inning of the Mets’ 13-2 pounding by the Nationals at Citi Field Sunday.

Recker, who said he last pitched in college at Alvernia University (Pa.), started the inning by walking Jayson Werth on four pitches and then served up a two-run homer to Ian Desmond. He retired the next three batters in his one inning of relief.

“Obviously, it was a situation where I could help out by pitching an inning and saving the bullpen a little bit,” Recker said. “(Collins) came up to me in the eighth inning. (Scott) Rice was warming up. He said if we have to bring Rice in the game, you’re going to throw the ninth. I said, ‘Okay.’ They told me to throw strikes.”

Recker’s fastball reached 88 mph. He said he had fun.

“I wish I could’ve gotten ahead of somebody so I could’ve thrown some off-speed stuff,” he joked.

Said catcher John Buck: “He threw straight. Just like a catcher.”

Recker became the first Mets position player to pitch since backup catcher Rob Johnson on May 18, 2012, at Toronto.
