Morse was in visible pain after a 2-2 changeup hit him on the hand, near the end of the bat. After the Washington training staff came out to take a look, Morse returned to the dugout. X-rays were negative, meaning there are no broken bones, but manager Davey Johnson said Morse would likely sit the second game of the series.
"The good news is it's not broken," Johnson said. "X-rays were negative. He's got a bad bruise, but hopefully he'll be all right in a few short days."
Without Morse and shortstop Ian Desmond (right hamstring) in the lineup Friday, the Nationals managed just six hits -- including a pinch-hit two-run homer from Tyler Moore.
"It was definitely a blow for us, but it's kind of what we've been dealing with all year," Moore said. "Guys stepping up in different situations. Just another day. We're hoping Mikey's hand is fine and Desi's fine. We'll see tomorrow."
Roger Bernadina pinch-ran for Morse in the first and remained in the game in left field. Bernadina went 1-for-2.
Morse, who missed time earlier this season with a right lat strain, is batting .286 with 12 home runs and 45 RBIs.
"Any time you get hit in the hands, it's kind of nerve-wracking, but X-rays came out negative and stuff, so I should be all right," Morse said.
