PHILADELPHIA, Pennsylvania, Oct 2, 2008 (AFP) - Shane Victorino hit a grand slam and Brett Myers pitched seven solid innings for the Phillies Thursday as they took a commanding lead over Milwaukee in their National League first round playoff series.

The Phillies beat the Brewers 5-2 to take a 2-0 lead in the best-of-five series.

Victorino took advantage of some wildness by Brewers starter CC Sabathia in the second inning.

After Pedro Feliz drew Philadelphia even at 1-1 with an RBI double, Sabathia got Carlos Ruiz to ground out before failing to put away Myers during a nine-pitch at-bat, eventually walking the opposing pitcher.

Jimmy Rollins walked on four straight pitches to load the bases, and Victorino belted a 1-2 pitch into the stands in left field to give the Phillies a 5-1 lead.

It was the first grand slam in postseason history for the Phillies.

Righthander Myers, who walked in a run in the first, settled in with the lead and retired 16 of 17 batters between the end of the first and the beginning of the seventh inning.

He was charged with two runs and two hits, walked three, struck out four and hit one batter.

The Chicago Cubs were hosting the Los Angeles Dodgers later Thursday in game two of their National League series.

The Cubs, who last won the World Series in 1908, lost game one at home and sent ace Carlos Zambrano to the mound in a bid to even the series.
