from the Washington Nat's website:
PHILADELPHIA -- On Tuesday, one day after watching the bullpen blow a four-run lead, the Nationals decided that right-hander Joel Hanrahan will no longer be their closer and that Garrett Mock is out as the eighth-inning setup man.
The team will go with a bullpen-by-committee, with right-handers Julian Tavarez and Kip Wells as the late-inning options. Once left-hander Joe Beimel is activated from the disabled list next week, he will most likely be the closer, with Tavarez and Wells becoming the setup men.
In the bottom of the eighth on Monday, the Nats had an 11-7 lead, but Mock and Hanrahan couldn't get the job done.
With Mock on the mound, Shane Victorino hit a sacrifice fly to bring in Pedro Feliz and make it 11-8. After Chase Utley singled in Jimmy Rollins, Hanrahan entered the game and couldn't find the strike zone, walking both Ryan Howard and Jayson Werth on 10 pitches.
Raul Ibanez then came to the plate. Hanrahan felt he had no choice but to throw a fastball, and he paid the price, as Ibanez hit a grand slam. It was Hanrahan's third blown save of the season.
"I hope I don't wear out this word, but, again, it was deflating," manager Manny Acta said. "Our offense just battled all day and scored enough runs. We played so hard for eight innings to score enough runs. You lose the game in one inning, it's just tough for the whole team." http://washington.nationals.mlb.com/new ... p&c_id=was
