Washington, DC - A pair of newcomers for the two-time defending National League-champion Philadelphia Phillies opened the 2010 campaign with a bang, as Roy Halladay hurled seven stellar innings and Placido Polanco drove in six runs -- four via a grand slam -- in an 11-1 drubbing of the Washington Nationals.
Halladay (1-0), acquired in a three-team trade in the off season from Toronto, struck out nine and allowed one run on six hits and a pair of walks for Philadelphia, which lost to the New York Yankees in last year's World Series after winning the 2008 crown. Halladay also knocked in a run in his NL debut.
Polanco, a free-agent signing in the winter, finished 3-for-5 while Ryan Howard added a two-run shot for the Phillies, who received two hits, two walks, two runs scored and an RBI from Jimmy Rollins in the resounding win.
John Lannan (0-1) made his second consecutive Opening Day start for the Nationals and gave up five runs -- all in the fourth inning -- on seven hits and three walks in 3 2/3 frames.
Ryan Zimmerman , who caught President Barack Obama's ceremonial first pitch, knocked in the only run in the loss. Ivan Rodriguez had three of the nine hits for Washington, which finished 2009 in last place in the NL East for the fifth time in six seasons.
The Phillies had lost their previous four season openers and were down 1-0 on Monday before batting around in a game-altering fourth frame.
Chase Utley led off with a walk and Howard followed with a shot into the first row of seats high over the right-field wall. Back-to-back hits to right from Jayson Werth and Raul Ibanez preceded Shane Victorino's RBI single.
Halladay helped his cause with a dribbler out in front of the plate to score Werth, the second career RBI for the lifetime American Leaguer. Rollins walked to load the bases and Polanco's flyout to left was deep enough to bring in Victorino.
Jesse English relieved a flustered Lannan after a walk to Utley and retired Howard on a routine groundout to second.
English hurled a scoreless fifth, but the Phils tacked on two more off Miguel Batista in the sixth. Rollins' stand-up triple drove in Carlos Ruiz, who led off the inning with one of his three walks, and Polanco's hit through a drawn- in infield made it 7-1 in favor of the visitors.
Batista stayed in for the seventh and loaded the bases. Jason Bergmann entered with two outs and was greeted by Polanco, who took the second pitch over the left field wall and into the bullpen for his second career grand slam.
The 10-run cushion was plenty for Halladay, who faced the minimum from the third through the sixth innings before being pulled after just 88 pitches.
After Rollins was thrown out at home to end the home first, Nyjer Morgan beat out an infield single to open the home half and immediately stole second. Zimmerman came up two batters later and doubled off the right-center field wall to push across the first run of the season.
