PHILADELPHIA -- While their injury list keeps growing, the Philadelphia Phillies are piling up victories.
The two-time NL champion Phillies moved within 3 1/2 games of East-leading Atlanta, cutting the deficit in half over the last five days. They've won nine in a row at home, their longest since winning 16 straight at Veterans Stadium in 1991.
It may have been a costly win for Philadelphia because center fielder Shane Victorino left in the seventh with a left oblique strain. He'll be examined by a team physician on Wednesday.
"I don't think it's that bad, but I'll know more after I take the MRI in the morning," Victorino said.
If Victorino has to go on the disabled list, top prospect Domonic Brown is a candidate to replace him.
"I think Domonic is always a consideration," manager Charlie Manuel said.
David Herndon (1-2) allowed two runs -- one earned -- in one inning to record his first major league victory.
Mark Reynolds hit his 24th homer for the Diamondbacks, who have the third-worst record in the majors.
"We weren't able to execute what we wanted to do offensively and defensively," Arizona manager Kirk Gibson said.
After the Diamondbacks scored two runs off Herndon in the sixth to go up, the Phillies answered with three in the bottom half to take a 7-5 lead.
The 2006 NL MVP has been Philadelphia's most consistent hitter in a lineup that's been riddled by injuries and inconsistency. The All-Star first baseman is batting .302 with 23 homers and a NL-leading 81 RBIs.
"We've had so many injuries, but we have to continue to go," Howard said.
Both starters pitched five innings. Cole Hamels allowed three runs and six hits, striking out eight. It was his shortest outing since lasting four innings against Toronto on June 26. The 2008 World Series MVP finished the month with a 2.16 ERA in six starts, but only got one win.
Lopez gave up four runs and seven hits against his former team. He was 3-1 in seven games with the Phillies last year.
The Diamondbacks went up 5-4 on a quirky play in the sixth. Chris Young led off with a double and Kelly Johnson walked. Gerardo Parra reached on Howard's throwing error and scored on Adam LaRoche's sacrifice fly to tie it at 4. Miguel Montero followed with a grounder to second baseman Placido Polanco. Parra ducked from Polanco's tag and beat the return throw from Howard to second, allowing the go-ahead run to score.
Reynolds hit a solo shot to tie it at 2 in the fourth. He walked with the bases loaded to force in Arizona's first run in the first.
Hamels hasn't had much luck this season. He's just 7-7 despite giving up three earned runs or less in 17 of his 21 starts and two or less 11 times.
"You have to be able to execute pitches and get quick outs," Hamels said.
