Game 143 lineups: Nats vs. Phillies

Manager Dusty Baker said Saturday he was going to start the youngsters in Sunday's series finale against the Phillies so his regulars can have two full days off before the Braves arrive Tuesday night.

And with a win and a Marlins loss today, the Nationals will lock up their second consecutive National League East crown, and fourth in six seasons.

Monday is a scheduled day off. The only regular starter in the lineup is Trea Turner. The big deal is that top prospect Victor Robles makes his first major league start in center field, batting fifth.

Wilmer Difo and Rafael Bautista, also starting today, were on the initial high Single-A Potomac 2015 roster. Robles was on the 2016 low Single-A Hagerstown Suns opening day roster.

Right-hander Stephen Strasburg (12-4, 2.78 ERA) gets the start for the Nats. He has allowed only two earned runs in his last five starts and six total earned runs since July 3.

Right-handed rookie Ben Lively (3-5, 3.92) gets the call for the Phillies. Lively is 2-2 with 2.73 ERA in four career starts in the National League East this season.

The Nats lead the season series with the Phillies 9-6 and are 6-3 in D.C. They face off one more time this season, Sept. 25-27 in Citizens Bank Park.
