Werth reported to AT&T Park in good spirits, walking without a boot on his sore right ankle and saying he felt "much better" than he did Monday, when he was a late scratch from Washington's lineup. Werth underwent a precautionary MRI on the ankle Tuesday morning, and the results came back negative.
Nationals manager Davey Johnson wasn't 100 percent confident when he met with reporters that Werth would be at full strength, but he was not scratched from the lineup after going through batting practice before the game.
Morse, on the other hand, was held out due to a jammed right thumb and may not return until Friday. Morse exited Monday night's 14-2 win early after jamming the thumb during batting practice, though he said after the game he expected to play Tuesday.
"The big guy is down. His big thumb is barking," Johnson said. "Probably the cooler weather doesn't help that. I guess it got jammed too many times."
Johnson hoped to start Morse against Giants right-hander Tim Lincecum in Wednesday's series finale but acknowledged he may not return until Friday's series opener against the Mets, giving him an extra day to rest.
"If he's able to go [Wednesday], I'll definitely have him in there," Johnson said.
