Recap: Philadelphia vs. Washington

Philadelphia, PA (Sports Network) - Michael Morse clubbed two homers and drove in four, helping the Washington Nationals move closer to clinching the NL East with a 7-3 win over the Philadelphia Phillies in the rubber match of a three- game series at Citizens Bank Park.

Bryce Harper hit a solo homer and added an RBI single for the Nationals, who reduced their magic number for securing the division title to three. Gio Gonzalez (21-8) overcame a shaky first inning to pitch six frames and become the major's first 21-game winner.

"I just couldn't find the strike zone. I was a little out of whack. After the first inning, I kind of settled in," Gonzalez said.

Tyler Cloyd (2-2) surrendered six runs on six hits in five-plus innings for Philadelphia, which has been all but eliminated from playoff contention. The Phillies are six games behind St. Louis for the second wild card spot with six to play.

Harper's first-inning blast staked Gonzalez to an early lead, but the Phillies jumped on the Cy Young Award candidate for three, two-out runs in the bottom of the first.

Chase Utley's single kept the inning alive and Gonzalez walked the next two batters to load the bases for Darin Ruf, who cleared them with a double to center field.

"It was a fastball, a pretty good pitch down," recalled Ruf. "I stayed with it and hit it over Bryce's (Harper) head."

It was all Nationals after Gonzalez's hiccup.

Morse homered to lead off the second and tied the game with a groundout in the fourth. Harper plated Danny Espinosa with a two-out single in the next inning and Morse followed Adam LaRoche's leadoff double in the sixth with a home run to center field.

Eury Perez, who came off the Washington bench to pinch run for Mark DeRosa, scored on wild pitch in the seventh.
