Game 135 lineups: Nats at Mets (Turner wins rookie of month)

NEW YORK - They took last night's series opener in impressive fashion. Now the Nationals try to take the series from the Mets and expand their growing lead in the National League East beyond their current 10 1/2-game cushion.

It'll be Tanner Roark on the mound tonight at Citi Field, and he has been awfully good against the Mets this season (one earned run, five hits in 9 1/3 innings). Rookie Robert Gsellman (whose name apparently is pronounced like "Gazelle-Man") makes his second career start for New York.

Ryan Zimmerman is back in the lineup for the Nationals, who have all their regulars in there for this one.

Looking ahead: It appears the Nats will be pushing Max Scherzer's start back from Sunday night to Monday afternoon, something Dusty Baker suggested was a possibility the other day. Reynaldo Lopez, who is eligible to be recalled from Triple-A Syracuse, is now listed as the series for Sunday's nationally televised series finale.

Meanwhile, Trea Turner has been named NL Rookie of the Month for August. Turner hit .357 with five homers, 15 RBIs, 27 runs and 11 stolen bases...
