Heath Bell threw the exhausting total of 45 pitches in Thursday's ninth inning before he gave up a hit. But that wasn't exactly good news for the Miami Marlins and their beleaguered closer because that hit by Kirk Nieuwenhuis – a long single to right – followed four Bell walks.

And it ended up costing the Marlins the game.

On a wet and dreary afternoon at Citi Field, the Marlins dropped a 3-2 decision and returned home to Miami having lost all five games on a road trip that was as dismal as Thursday's weather.

The Mets walked off with the series sweep on Nieuwenhuis' winning hit, and Bell trudged off the mound with his third blown save in five tries. Because his services were unnecessary during the first four games of the trip, Bell sprinted in from the bullpen Thursday having not pitched in a week.

But he said the lack of game activity had nothing to do with his sour performance. In fact, he sounded angry when he volunteered that a member of the team's training staff questioned his work habits, saying he was doing too much, not too little.

"Apparently our trainer says I work too hard," Bell said. "I'm busting my [butt] on the treadmill, the bike and working out. Maybe I need to start listening to him and stop working so hard. I do everything you should do, do everything I've been doing for the last five, six, seven years."

Bell refused to elaborate further.
