NEW YORK (WFAN/AP) — Jason Bay’s mid-season rebound may have been a bit premature.

Bay, just 3 for 30 with no RBI dating back to July 6, is starting to hear the boo-birds at Citi Field. Many Mets fans are beginning to wonder — again — what’s wrong with their star left fielder?

Thanks to an 8-5 loss on Sunday, the Mets dropped two of three to the Phillies for the fourth time this season. Bay was a major culprit yesterday, batting 0 for 4.

But that’s not all. Bay’s woes in the batter’s box made their way onto the field against Philadelphia.

Phillies infielder Jimmy Rollins knocked a two-run single in a three-run eighth inning Sunday — aided by an earlier Bay error in left field.

Booed all day, Bay came charging in on Ryan Howard’s sinking liner. The ball hit off the top of his glove for an error to start the frame.

“I missed it,” Bay said. “It’s one of those things where I missed it.”

Batting third for Carlos Beltran, Mets outfielder Willie Harris had a single and a double — but was stranded in scoring position each time by Bay.

“I mean it’s not the first time. Believe me. If you imagine how frustrated the fans are, do you think I enjoy it, what I’m doing out there?” Bay said after the loss. “I’m more frustrated than anybody, but I have to come back and do this every single day. I can’t get caught up in the frustration.”

With the Mets struggling to remain relevant before the July 31 trading deadline, can they afford to keep Bay in the lineup? Let’s hear it in the comments below…
