Jayson Werth left the Nationals' 2-0 loss to the Diamondbacks on Tuesday night in the ninth inning after straining his groin chasing an Ian Kennedy base hit in the seventh.
(At least, we think it was his groin. That's what a Nationals spokesman said, though manager Davey Johnson called it a hip flexor and Werth said both groin and hip flexor in an otherwise coy response to the question. In the NHL, this would be called a "lower body" injury.)
At any rate, Werth said his removal from the game was precautionary.
"It could just be a muscle spasm, I don't know," Werth said. "We'll see how it feels tomorrow. It's real mild. I don't think it'll be a big deal. Whether Davey wants to play me tomorrow or not, I don't know. But it's part of it. You deal with these things. You get dinged up. You get strains and sprains over the course of the season. I don't think it's anything that should keep me out too long."
