Washington, DC (Sports Network) - Steve Lombardozzi knocked in two runs and the Washington Nationals inched closer to securing the NL's top seed with a 4-2 victory over the Philadelphia Phillies.
The Nationals, who won the NL East on Monday, can secure home-field advantage throughout the playoffs if the Reds lose to the Cardinals on Tuesday. Cincinnati and Washington entered Tuesday's play with identical records, but the Nationals own the tiebreaker for winning the season series.
Adam LaRoche hit a solo homer for Washington, which bounced back from a 2-0 loss in the opener of this three-game series on Monday. The home run gave LaRoche 100 RBI on the year, making him the third player to record a 100-RBI season in a Nationals uniform.
Tom Gorzelanny, making his first start of the season for the Nationals, allowed one run on four hits over 3 2/3 innings. Zach Duke (1-0) pitched a scoreless sixth to pick up the win.
Darin Ruf hit a pair of solo homers for the Phillies, who are out of the playoff picture for the first time since 2006.
B.J. Rosenberg gave up one run on three hits over four innings in his first start in the big leagues. Josh Lindblom (3-5) allowed two runs on three hits in the sixth to take the loss.
The Phillies (81-80) need a victory on Wednesday to secure a winning record for a 10th consecutive season.
