Bryce Harper also won’t start the first game either, as the Nationals face left-handed starter Brad Hand. Manager Davey Johnson said Harper will play in the day’s second game.

The stomach virus first started bothering Morse on Thursday night but he still played. He didn’t receive his antibiotic medicine until Friday morning and hasn’t been able to eat in about a day, Johnson said.

Jayson Werth, who returned from the disabled list on Thursday, will start in center field in the first game and sit the second game.

Jordan Zimmermann, who has had some recent difficulty getting his shoulder loose while playing catch, reported feeling great after his throwing session in between starts on Thursday, Johnson said.

“He said it feels like you’re throwing through a brick wall,” Johnson said. “That’s good news.”

Zimmermann was originally slated to start on Friday but had his start pushed back to Saturday because of his shoulder tightness. He has been taking anti-inflammatory medicine for it. He has been the Nationals most consistent starter, leading in several pitching categories such as ERA, WHIP and innings.
