NATIONAL LEAGUE

Phillies 2, Astros 1

Roy Halladay struck out eight in his first NL complete game, and Philadelphia completed a sweep of winless Houston Sunday.

Halladay (2-0) scattered seven hits and retired the last nine batters he faced. Acquired from Toronto in an offseason trade, the former AL Cy Young Award winner pitched his 50th career complete game and outdueled Roy Oswalt (0-2).

Houston dropped to 0-6. The two-time NL champion Phillies improved to 5-1.

Oswalt also struck out eight and allowed five hits in six innings, but lost for the first time in his last seven decisions against Philadelphia.

Nationals 5, Mets 2

Josh Willingham wound up with a grand slam off Johan Santana after a wild sequence in the first inning capped by an instant replay review, leading Washington to the victory.

Willingham's drive hit the wall in left-center and was initially ruled in play. He tried to stretch his triple when the ball got away from catcher Rod Barajas and was tagged out, leaving both players sprawled across home plate.

After checking the replay, the umpires ruled a home run.

Willingham also had an RBI double in the third inning, helping the Nationals beat Santana (1-1) for the first time since June 9, 2007.

Brewers 8, Cardinals 7

Casey McGehee homered with one out in the bottom of the ninth inning, lifting Milwaukee to a victory over St. Louis after the Cardinals rallied against closer Trevor Hoffman.

Hoffman was protecting a 7-4 lead with two outs in the top of the ninth when baseball's career saves leader unraveled for the second straight appearance. Albert Pujols hit his second two-run homer of the game to cut the lead to one, and Matt Holliday followed with a tying shot.

But McGehee connected off Kyle McClellan (0-1) with one out in the bottom half to give Hoffman (1-1) an unlikely victory and help the Brewers avoid a three-game sweep after they tagged Cardinals ace Chris Carpenter for three homers and seven runs.

Giants 6, Braves 3

Tim Lincecum struck out 10 and overcame an early home run, Pablo Sandoval hit a two-run shot and San Francisco beat Atlanta in a game that finally started after a rain delay of 4 hours, 9 minutes.

Lincecum (2-0), the two-time reigning NL Cy Young Award winner, recorded his 20th career outing with 10 or more strikeouts.

Diamondbacks 15, Pirates 6

Arizona pitcher Edwin Jackson hit the first homer of his career, capping a team-record 13-run burst in the fourth inning.

Chris Young and Kelly Johnson also connected during the big inning that featured eight hits, including two by Jackson.

Reds 3, Cubs 1

Mike Leake pitched into the seventh inning during his wild major league debut and Ramon Hernandez drove in the go-ahead run for Cincinnati with a bases-loaded walk.

Leake became the 21st player since the draft began in 1965 to play in the majors without appearing in a minor league game and first since Xavier Nady with the San Diego Padres in 2000. He also became the first American pitcher to accomplish the feat since Darren Dreifort with the Los Angeles Dodgers in 1994.

Marlins 6, Dodgers 5

Jorge Cantu tied a career high with five RBIs, and the Marlins rallied past the Dodgers for the second time in less than 18 hours.

Florida trailed 4-0 before Cantu hit a three-run homer in the fourth. He put the Marlins ahead 6-5 with a two-run double in the seventh off Jeff Weaver (0-1).

Rockies 4, Padres 2

Ubaldo Jimenez pitched six effective innings, Troy Tulowitzki hit a two-run double and Colorado won the deciding game in the first series of the season between the NL West rivals.

Miguel Olivo homered and Seth Smith added an RBI single for the Rockies, who bounced back from Saturday night's 5-4 loss to the Padres in 14 innings, the longest game in the majors this season. Franklin Morales got three outs for his second save in as many chances.

AMERICAN LEAGUE

White Sox 5, Twins 4

J.J. Hardy was nailed at the plate for the final out when he tried to score on pinch-hitter Jim Thome's long drive, and the Chicago White Sox held off the Minnesota Twins.

Hardy singled with two outs against Bobby Jenks and took off when Thome hit a shot into the left-center field gap. Left fielder Juan Pierre retrieved the ball on the warning track and threw to third baseman Mark Teahen.

Teahen's relay to catcher A.J. Pierzynski arrived in plenty of time, and Hardy was beaten by so much that he didn't slide or go barreling home.

Tigers 9, Indians 8

Carlos Guillen scored on fill-in closer Chris Perez's wild pitch with two outs, capping a three-run ninth inning and lifting the Detroit Tigers over the Cleveland Indians.

Guillen hit an RBI double to get the Tigers within a run. After Brandon Inge grounded out, Perez (0-1) issued consecutive walks to Ramon Santiago and Johnny Damon to force home the tying run. His next pitch bounced past Lou Marson, allowing Guillen to scamper home.

Athletics 9, Angels 4

Adam Rosales homered in his first AL at-bat, added a go-ahead single and finished with four RBIs as the Oakland Athletics beat the Los Angeles Angels.

Rosales, a backup infielder with Cincinnati the last two seasons, hit a solo home run in the second inning and sprinted around the bases. His drive was Oakland's only hit through the first six innings against Joe Saunders (0-2).

Rangers 9, Mariners 2

Scott Feldman pitched seven solid innings and Michael Young homered, helping the Texas Rangers beat the Seattle Mariners.

Vladimir Guerrero finished with three hits for Texas, boosting his average to .500, and Joaquin Arias had his second straight three-hit game.

Blue Jays 5, Orioles 2

Jose Bautista and Alex Gonzalez hit consecutive homers in the eighth inning after a two-out error by Miguel Tejada, and the Toronto Blue Jays beat the Baltimore Orioles for a three-game sweep.

Kevin Millwood (0-1) took a three-hitter and a 2-1 lead into the eighth. He retired the first two batters before Tejada - a career shortstop now playing third base - misplayed a sharp grounder by East Lyme's John McDonald.

Bautista then homered and Gonzalez followed with his second home run of the game.
