Washington Nationals name Joe Ross as starter for tonight’s series finale against Atlanta Braves...

With Max Scherzer unable to return from the Injured List in time to make the start tonight, the Washington Nationals were expected to turn to right-hander Austin Voth in the finale with the Atlanta Braves in SunTrust Park.

That plan was up in the air as well as of Saturday afternoon, however, when skipper Davey Martinez told reporters that Voth experienced some tenderness in his right shoulder while throwing a bullpen session between starts.

“Well, now we don’t know what’s going to happen,” Martinez told reporters, as quoted by MASN’s Mark Zuckerman, on Saturday afternoon, before the third game of the four-game series.

“We’ll talk to Voth tonight and we’ll see, go from there.”

Joe Ross headed from Fresno, CA to Georgia to join the Nats in Atlanta as they prepared to play the third of four with the Braves, and the reason for his cross-country trip became clear after Martinez’s announcement.

Ross, the manager said, along with Erick Fedde, would be an option if Voth was unable to go, and the Nationals wanted to get a look at Ross after he’d altered his mechanics while working at Triple-A

“[Pitching Coach Paul Menhart] wanted to see him throw,” Martinez explained. “They changed his mechanics a little bit, so Paul wanted to put eyes on him.”

After the Nationals’ 5-3 win over the Braves last night, the second-year manager made it official. Ross is getting the nod tonight as the visiting team tries to take 3 of 4 from their divisional rivals.

“It won’t be Voth, it will be Joe Ross.”
