LAKE BUENA VISTA, Fla. -- Nationals left fielder Michael Morse was a late scratch on Tuesday because of right lat (back) strain. He is listed as day to day. Bryce Harper, who was slated to enter the game late, started in right.
Morse said he started feeling pain in his back the last couple of days. He is having difficulty throwing the baseball.
"My back felt kind of tight. The other day, I was DHing and I didn't have to do any kind of throwing, so I took the day off that day and yesterday [I wasn't playing]," Morse said. "Today, just warming up, it felt kind of tight. There is no reason to push it this early. It's something that I need a little break, a little rest. Probably a little overworked or something."
Manager Davey Johnson said that he plans to be conservative with Morse, so look for Morse to be out of action for a few days.
In other news, Johnson said that outfielder Jayson Werth suffered forearm tightness in Tuesday's game against the Braves, but the injury is not considered serious. Werth had an opposite-field home run in the second inning and went 1-for-2 in the contest.
