PHILADELPHIA -- First baseman Ryan Howard and shortstop Freddy Galvis hit two-run homers as the Philadelphia Phillies beat the Miami Marlins 7-3 on Tuesday night.

Left fielder Ben Revere added a two-run triple for the Phillies, who won for just the second time in nine games.

Right fielder Giancarlo Stanton hit his third homer of the season for the Marlins, who have dropped five straight.

Howard's homer, his first of year, came in the sixth inning off Miami starter Dan Haren (1-1) and erased a 3-2 Marlins lead. Revere added his triple in a three-run seventh. It came one pitch after reliever Mike Dunn knocked him down with a head-high fastball.

Philadelphia starter Jerome Williams (1-1) went six innings to earn his first victory of the season. He allowed eight hits and three runs (two earned), while striking out six and walking one.

Luis Garcia, Ken Giles and Jonathan Papelbon each worked a scoreless inning in relief for the Phillies.

Haren allowed four hits and four runs in six innings of work. He struck out seven and walked three.

Galvis lined a 1-1 pitch from Haren into the right-field seats with Howard aboard in the second, giving the Phillies a 2-0 lead. It was Galvis' first homer of the season.

Stanton's homer was a 449-foot solo blast into the Marlins' center-field bullpen with one out in the fourth.

The Marlins took the lead by scoring twice in the fifth on an RBI single by shortstop Adeiny Hechavarria and an error by Howard.

NOTES: According to MLB.com, manager Mike Redmond met with owner Jeffrey Loria and general manager Dan Jennings before the game, in the wake of a report Sunday saying that the manager's job was in jeopardy. "I'm not interested in any palace intrigue -- period," Loria told MLB.com. "It doesn't have anything to do with anything." ... Phillies RHP Chad Billingsley, on the disabled list since March 27 after right flexor tendon surgery, missed his rehab start Monday because of "a stomach issue -- a virus or something like that," manager Ryne Sandberg said. Sandberg is uncertain when Billingsley will make his next appearance. ... Phillies OF Domonic Brown, on the disabled list since March 27 with left Achilles tendinitis, is continuing his rehab assignment at Triple-A Lehigh Valley. Brown went 1-for-13 in his first three games with the IronPigs. Sandberg said Brown will return to the majors when he regains his stroke. ... Marlins LF Christian Yelich was a late scratch from Tuesday's lineup with lower-back tightness. ... Before the game the Marlins optioned RHP Jose Urena to Triple-A New Orleans and selected the contract of RHP Nick Masset from the same affiliate. Masset then worked a perfect inning in relief.
