Josh Beckett not only was ineffective Monday, he was unhealthy.

The Dodgers could add one more injury to their already long list after a 6-2 loss to the Washington Nationals in front of an announced crowd of 32,337 at Dodger Stadium.

The problem with Beckett, who tweaked his groin making a play in the field, is the problem with the Dodgers. The injuries are inextricably linked to the ineffectiveness, but it's tough to separate the two.

The right-hander proclaimed himself healthy after his first seven starts, during which he failed to win a game and racked up an 0-4 record and 5.13 ERA.

Beckett wasn't sure if he would be able to make his next start and said, "I'd hate to tell you yes, then come in tomorrow sore."

Monday's start was Beckett's shortest of the season - three innings - and he left with a 4-0 deficit. But he refused to blame the state of his body or his mind.

"I try to make pitches and I'm not doing a very good job of that right now," Beckett said after falling to 0-5.

He and Dodgers manager Don Mattingly said the pitcher has been dealing with other injuries not related to the groin since his last start, but they wouldn't say what those were. Mattingly only said he believed Beckett was healthy in his first seven starts.

The Dodgers' fate Monday wasn't all Beckett's fault. A series of errors helped Washington score six runs before the Dodgers got on the scoreboard and Bryce Harper crashed into it.
