Kyle Schwarber blasted his 39th and 40th homers and drove in six runs to ignite the Philadelphia Phillies to a 13-3 home win over the Baltimore Orioles on Monday.

Schwarber's grand slam capped an eight-run sixth inning for Philadelphia, which scored all of those runs with two outs.

Recently acquired Harrison Bader hit a go-ahead three-run homer earlier in the frame -- his first home run since joining the Phillies -- while three other Philadelphia players homered in the game, including Bryce Harper.

Jesus Luzardo (10-5) worked six solid innings to earn the win, allowing three runs and five hits (including two early home runs). He struck out seven and did not walk a batter to help Philadelphia win for the fourth time in six games.

Tyler O'Neill and Jordan Westburg each went deep for Baltimore, which has lost four of its last five games. Orioles starter Cade Povich (2-6) gave up four runs and four hits in 5 2/3 innings before the flood gates opened.

Philadelphia was trailing 3-1 in the third inning when Schwarber launched a mammoth two-run home run off Povich. The score remained deadlocked until the hosts embarked on a massive two-out rally in the sixth.

With nobody on and two down, J.T. Realmuto narrowly beat out an infield single that the Orioles challenged, but to no avail. Nick Castellanos then greeted Corbin Martin with a single before Bader smacked a home run to left to make it 6-3.

It was the 13th home run of the season for Bader, who was acquired in a trade with the Minnesota Twins prior to last week's trade deadline.

The next four hitters reached base for the Phillies, including an RBI single by Weston Wilson, before Yaramil Hiraldo came on to face Schwarber with the bases loaded. The All-Star Game MVP then sent Hiraldo's second pitch over the fence in right field to make it 11-3.

Edmundo Sosa and Wilson added back-to-back home runs in the eighth to cap the scoring.
