The Mets have a knack for finding new and inventive ways to lose. Even by their impressive standards, yesterday’s 2-1, 20-inning setback to the Marlins was unique.

It’s not everyday a team goes 0-for-19 with men in scoring position and leaves 22 runners aboard. But that remarkably anemic performance in the clutch is exactly what the tiny crowd at Citi Field was forced to witness for an agonizing six hours and 25 minutes.

Eleven different Mets had chances with men in scoring position, with Rick Ankiel and Omar Quintanilla each going 0-for-3, and Marlon Byrd, Justin Turner, John Buck and Lucas Duda doing the honors twice apiece. They failed in all manners with men aboard, by striking out, hitting into tough luck and failing to move runners over.

“We drove a few balls hard in the outfield — with them playing no-doubles was the difference,” Buck said. “It’s not like we didn’t hit the ball hard. We did strike out a couple of times, didn’t get it done with guys on third. The combination of that obviously isn’t good.”

There were questionable decisions (Buck attempting to bunt in the 13th with Turner on first was one example), one great play by the Marlins and a lot of inability by the Mets to execute fundamentals.
