PHILADELPHIA -- Ryan Zimmerman homered, drove in three runs and led the Washington Nationals to a 6-2 victory over the Philadelphia Phillies on Saturday night.

A.J. Cole (1-0) allowed one run over six innings in his first start of the season and helped the Nationals win their fourth straight game.

The Nationals lead the majors with a 21-9 record and won the last two games without 2015 NL MVP Bryce Harper. Harper strained his left groin on Thursday and could return to the lineup Sunday.

Without Harper, Zimmerman did his best to carry the offense.

Zimmerman leads the league in hitting, hits, home runs, RBIs, and a slew of other major offensive categories. He was robbed of a homer in the second inning on a leaping catch by centerfielder Odubel Herrera.

No one but a fan had a chance of snagging Zimmerman's two-run shot to left in the in the fourth. His 13th homer of the season gave the Nationals a 2-1 lead and gave him a 13-game hitting streak.

Anthony Rendon hit a three-run homer off Phillies starter Vince Velasquez (2-3) in the sixth.

Cole, a 25-year-old righty, made seven starts last season for the Nationals and was called up this week when Joe Ross was demoted to Triple-A Syracuse. Cole had to make his first start Saturday because he first had to serve the final three games of a five-game suspension levied last season for throwing at Pittsburgh Pirates third baseman Jung Ho Kang.

Cole struck out two, walked four and gave up six hits.


Zimmerman almost gave him a lead in the second on a deep shot to center that sent Herrera sprinting toward the 401 sign and he made the catch against the fence before it landed 402 feet away.

Velasquez raised his arms in triumph as if he pitched a no-hitter.

He needed more defensive help in the sixth. Zimmerman lined one the opposite way to right that Brock Stassi seemed to lose in the lights. Zimmerman's shot sailed over Stassi for an RBI double and a 3-1 lead. Rendon followed with his fifth homer of the season for a 6-1 lead that sealed the win.

Cameron Rupp added a solo shot for the Phillies, who lost their fifth straight.
