Young (1-0) left with a 7-0 lead after throwing 101 pitches. The only hit off him was a high-hopper down the third-base line by Hanley Ramirez that rolled into the outfield for a double.
Florida finished with six hits.
Mets 3, Nationals 1
Pedro Martinez escaped a bases-loaded, no-out jam and finished with seven strong innings in New York's victory over Washington for the Mets' fifth straight win.
After the Nationals loaded the bases in the sixth, Martinez (2-0) struck out Jose Vidro for the first out and got Jose Guillen to hit into a double play, neatly turned by second baseman Anderson Hernandez, whose throw beat just beat Guillen.
Except for that one inning, Martinez was impeccable, allowing only three hits and walking one.
Pirates 9, Dodgers 5
At Pittsburgh, Craig Wilson hit a pair of two-run homers, including a go-ahead drive in the seventh inning, and Pittsburgh rallied for a victory over Los Angeles.
The Pirates rallied from three runs down against the Dodgers for the second night in a row -- they won 7-6 on Tuesday -- and did it again with home runs. Jack Wilson and Freddy Sanchez also homered. The Pirates have eight homers in the last two games.
Phillies 7, Braves 5
At Atlanta, Aaron Rowand hit a two-run homer, Pat Burrell also homered and Philadelphia won for only the second time this season.
The Phillies, who lost six of their first seven games, jumped ahead 4-0 in the second inning and held on at end. Wilson Betemit, filling in for injured third baseman Chipper Jones, hit a two-out, two-run double in the eighth that brought the tying run to the plate. But Arthur Rhodes struck out pinch-hitter Matt Diaz to end the threat.
Cardinals 8, Brewers 3
At St. Louis, Jim Edmonds hit a three-run double and scored on a pair of errors during a pivotal at-bat in the fifth inning, helping St. Louis beat Milwaukee.
Jason Marquis (2-0) worked around a three-run homer by Carlos Lee in an otherwise solid six-inning stint, and Scott Rolen had two RBIs to take the team lead with 11 for the Cardinals. St. Louis is 2-0 at new Busch Stadium after going 50-31 both on the road and at old Busch last season.
Diamondbacks 5, Rockies 4
At Phoenix, Luis Gonzalez drove in the go-ahead run with his 499th career double and Arizona rallied to snap Colorado's four-game winning streak in front 18,664 -- the smallest home crowd in the Diamondbacks' nine-year history.
Brad Hawpe misjudged Gonzalez's liner in the seventh inning and it sailed over the right fielder's head to bring home Chad Tracy from second. Conor Jackson tried to score from first but was thrown out at the plate.
