ATLANTA -- The Atlanta Braves knocked around Cole Hamels in the opener, then chased Roy Halladay in the fourth inning on Wednesday night. They have six homers through two games against the Philadelphia Phillies.
Jason Heyward just loves what he is seeing so far.
"Jumping out early is huge," he said. "It's not always going to happen, but it's nice to do and nice to give your pitcher that cushion."
Freddie Freeman had three RBIs and leadoff hitter Andrelton Simmons scored twice for Atlanta, which jumped in front for the second straight game and never trailed. Upton belted a two-run shot in the first to give him a pair of homers in his first two games with the Braves.
Halladay (0-1), who struggled with a sore shoulder last season and had a difficult spring training, gave up five runs and six hits in 3 1/3 innings. The two-time Cy Young Award winner struck out nine, but dropped to 0-4 with an 8.00 ERA in his last seven starts against Atlanta.
"I felt good," Halladay said. "Felt good in the bullpen, felt good on the mound. Obviously horrible conditions to pitch in. That made it no fun, but that's not an excuse for not being able to get ahead of guys and do it consistently and put guys away quicker."
The game was played in a chilly, steady drizzle, but the conditions hardly affected Maholm (1-0), who allowed six hits in 5 2/3 scoreless innings. He struck out six and walked one.
"It was good," Maholm said. "Obviously, in the first start of the year, not the greatest conditions, but I felt comfortable."
Gattis led off the fourth inning of his first major league game with a drive to left. Maholm struck out, but Halladay's night was over after he issued a walk to Simmons.
Raul Valdes came in and walked the next two batters before Freeman hit a bases-clearing double to make it 7-0. Freeman has driven in six of Atlanta's 16 runs in the first two games.
Maholm struggled last year against Philadelphia with an 8.64 ERA in two starts. But the left-hander stranded runners in scoring position in three of the first four innings in his first start of 2013.
The Phillies were just 1 for 11 with runners in scoring position.
"I thought (Maholm) did a terrific job," Braves manager Fredi Gonzalez said. "He mixed his pitches well and he did a nice job. Gave us a great opportunity to win the ballgame."
Juan Francisco also singled in a run in the first as Atlanta quickly built a 3-0 lead.
Halladay recorded his first eight outs on strikeouts, but he needed 79 pitches to make it through the first three innings. He was trying for win No. 200 and a spot alongside New York Yankees left-hander Andy Pettitte as the only active pitchers to be 100 games over .500.
Halladay was upset with himself for making such an early exit.
"I'd rather get beat 20-0 and pitch eight innings than pitch 3 1-3," he said. "That's got to change."
Chase Utley had a two-run double in the seventh for Philadelphia. Utley appeared to score a third run, but home plate umpire Mike Everitt called Michael Young out for runner's interference at first and the inning ended.
Heyward tacked on a two-run homer against Jonathan Papelbon in the eighth, but the Atlanta right fielder thought the key was making Halladay work.
"We did wear him down," Heyward said. "We did make sure that we got some pitches to hit and we hit them hard."
