Lo Duca reaggravates right hand injury

Lo Duca reinjures right hand

HOUSTON -- Washington catcher Paul Lo Duca reinjured his right hand swinging at a pitch in the seventh inning during Wednesday's 4-3 loss to the Astros.

The Nationals had put Lo Duca on the 15-day disabled list after he suffered a contusion in his right hand when he was hit by a pitch on April 13 by Atlanta's Jeff Bennett. He was activated last Friday.

"I felt a really, really sharp pain," Lo Duca said of swinging at an 0-1 pitch from Houston's Roy Oswalt with one out and nobody on in a tie game. "It's probably the most pain I've ever felt. I'll get an MRI tomorrow."

Lo Duca was 3-for-14 since returning to the lineup.

"You feel it here and there," Lo Duca said of the pain since being activated. "It's been tolerable, sore the last couple of days. Tonight it didn't feel right. I thought to myself, 'Keep both hands on the bat,' and I couldn't do it."

Lo Duca left the game immediately and Wil Nieves finished his at-bat, inheriting an 0-2 count and striking out. Nieves replaced Lo Duca behind the plate.
