Monday’s games

National League

Phillies 8, Nationals 4: Kenny Lofton hit a three-run homer and Jon Lieber pitched 5 2/3 effective innings, leading Philadelphia to a victory in the first game played by the Washington Nationals. Terrmel Sledge homered and drove in three runs for the Nationals, who moved during the off-season after 36 seasons as the Montreal Expos. Washington, which hadn’t had a major league team since the expansion Senators left for Texas following the 1971 season, plays its home opener April 14 against Arizona. After three years in limbo as the Expos, the Nationals came out Monday wearing gray jerseys with “Washington” in script across the chest in red, blue and gold.

Cubs 16, Diamondbacks 6: Aramis Ramirez led Chicago to a record-setting offense on Opening Day. Ramirez went 3 for 4 with a two-run homer and four RBIs, and the Cubs amassed 23 hits in a rout of Arizona in Phoenix. Chicago broke its old record for runs in an opener by one.

Reds 7, Mets 6: Adam Dunn hit a tying, two-run homer in the ninth, and Joe Randa followed with a solo shot off Braden Looper that sent Cincinnati to a thrilling win over visiting New York. Dunn also had a three-run homer in the first inning off Pedro Martinez, who had an otherwise electrifying New York debut, striking out 12 in six

Brewers 9, Pirates 2: Ben Sheets outpitched Oliver Perez in a matchup of two of the N.L.’s best young starters as Milwaukee won in Pittsburgh. Sheets allowed eight mostly harmless hits and two runs over seven innings, striking out six and walking none.

Rockies 12, Padres 10: Rookie Clint Barmes hit a two-run homer to cap Colorado’s four-run ninth inning off Trevor Hoffman, helping the Rockies open the season with a wild win over San Diego.

American League

White Sox 1, Indians 0: Mark Buehrle retired his first 12 batters and allowed two hits in eight innings as Chicago won a pitcher’s duel with visiting Cleveland. Cleveland’s Jake Westbrook was just as tough, allowing only two hits in the first six innings.

Orioles 4, Athletics 0: Sammy Sosa got two hits and Luis Matos homered as Baltimore beat Oakland in Baltimore. Making his Baltimore debut, Sosa singled in his first two at-bats and went 2 for 4.

Blue Jays 5, Devil Rays 2: Roy Halladay pitched seven strong innings, and Toronto got home runs from Vernon Wells, Orlando Hudson and Eric Hinske in a win over Tampa Bay in St. Petersburg, Fla.
