Another collapse for Mets bullpen in loss to Brewers

Remember those plucky, overachieving Mets?

Yeah, neither does anyone else.

Terry Collins, after watching his team fumble away another game and his makeshift bullpen collapse following an excellent start by R.A. Dickey, knows those days are a long time ago.

BOX SCORE

“I’ll take this one,” Collins said after the Brewers completed a three-game sweep of the Mets with a 6-2 victory at Citi Field.

“I have great confidence in my players. I think we can get the job done. I’ve obviously been wrong. We can’t stop anybody.”

The manager, prone to moments of strong, immediate reactions after games, had another yesterday — understandable considering the circumstances, since there’s only so many times you can watch a team make critical errors, fail in the clutch at the plate and not have anyone reliable in the bullpen and stay calm.

This loss featured all of them, from Manny Acosta (1-1) walking Nyjer Morgan to start the eighth, which led to the winning run. And that winning run scored on an error by Justin Turner, whose throw to second on a double-play attempt was wide and not handled by Ruben Tejada.

Jason Isringhausen had another tough outing, as did Pedro Beato.

The Mets (60-66) have lost five straight at home and now go to Philadelphia, where Cliff Lee awaits tonight.

Collins admitted he is concerned the progress the Mets appeared to have made earlier in the season might be lost if they don’t improve their play soon.

“We accomplished a lot of things this year, overachieving with some people,” Collins said. “I’m very concerned about the players right now with the way things have gone the last couple of weeks. Jose [Reyes] and [Daniel Murphy] went down and we had to pick ourselves up and have failed to do that.”

This weekend was especially ugly. They rallied for eight runs in the seventh and eighth on Saturday and still lost. And yesterday, Lucas Duda’s game-tying, two-run homer off Yovani Gallardo was followed by Jason Bay’s booming double that hit high up the left field wall and would have been a home run at “any other park in the universe,” according to Dickey.

Instead, Josh Thole’s bunt toward third failed to advance Bay — and Thole said he got a bunt sign though Collins said he bunted on his own.

Jason Pridie then popped to second and, after Tejada was intentionally walked, Collins opted to lift Dickey, who gave up just two runs in seven innings but failed to pick up a win for a fifth consecutive start, for pinch-hitter Willie Harris, who flied out to right.

It was a perfectly reasonable move for Collins, but one he second-guessed after the game, mostly out of frustration.

“I’m allowed to be frustrated,” Collins said. He and general manager Sandy Alderson have discussed adding depth to the bullpen, but Collins said there’s not much to choose from in the minor league system.

“We’ve pretty much had everyone from [Triple-A] Buffalo,” Collins said. “I don’t think there’s any questtion it’s gonna be discussed.”

If they do find someone, it would likely be just a shot in the dark, since the only pitcher Collins mentioned was Josh Stinson, who had a 7.44 ERA when he was at Buffalo.

“We’re kind of, for lack of a better term, limping,” Bay said. “We’re trying to fight through the end of the season.”
