Souza feeling better after crashing into wall

ATLANTA -- Nationals outfielder Steven Souza Jr. said he is feeling much better after colliding with the right-field wall during Friday's 7-6 loss to the Braves but is still a little sore.

Manager Matt Williams went so far as to say that Souza was available off the bench for Saturday night's game against Atlanta. Souza has undergone several concussion tests over the past 24 hours and has passed all of them.

The injury occurred in the bottom of the second inning. With Atlanta leading, 4-0, Freddie Freeman swung at a 2-1 pitch from right-hander Stephen Strasburg and hit a long drive to right field. Souza chased after the ball and collided with the wall at full speed as the ball went over the fence for a two-run homer.

Souza was on the ground for at least a minute, while Williams, athletic trainer Lee Kuntz and several teammates came to his aide.

Souza saw the video of the collision and was surprised that he wasn't seriously injured. He said the pad on top of the right-field wall prevented him from sustaining a head injury.

"There isn't much damage," Souza said. "I just think the impact of being stopped at full speed is kind of where we are at. It hit my shoulder and neck right there."

Werth scratched with sore shoulder, ankle

ATLANTA -- Nationals right fielder Jayson Werth was scheduled to hit third against the Braves on Saturday night, but at around 6 p.m. ET, Werth was scratched from the lineup because of right shoulder and right ankle issues.

Werth injured his ankle trying to stretch a single into a double against the Marlins on July 28. It's not known when Werth hurt the shoulder. Manager Matt Williams said that Werth hurt the shoulder making a catch at Nationals Park recently.

Werth had the day off Friday, and Williams thought Werth was going to play Saturday. Williams said Werth was "getting worked on right now."

"[Werth] has had a little bit of an issue with [the shoulder]. It has been sore on occasion," Williams said. "If he takes a funky swing or swings at a bad ball or something, then he gets sore again. He has been playing with it for a week and a half and he is playing pretty well, too."

Werth was not available for comment before the game.

Worth noting

Nationals outfielder Nate McLouth, who is on the disabled list because of right shoulder inflammation, said he was having issues with the shoulder before making a diving play against the Marlins on July 28. In fact, he said he's had problems with the shoulder since early in the season.

McLouth is currently doing exercises to strengthen the shoulder, and he hopes to start participating in baseball activities soon. McLouth hopes to return to the team before the end of August.
