Schwarber connected on his first of the day as the Phillies' very first batter, and he did it again with his next at-bat in the third inning for a pair of solo shots. He is second in the league in home runs, trailing only Aaron Judge of the New York Yankees.
While the Phillies got two RBIs from their lead-off hitter, the Braves got three from theirs, with Dansby Swanson leading the way for Atlanta offensively.
Swanson finished three-for-six, including a massive 417-foot two-run home run in the fourth inning to turn a 4-3 deficit into a 5-4 lead.
After a pair of sacrifice-flies from Phillies Bryce Harper and Alec Bohm in the fifth inning, William Contreras tied things at 6-6 in the eighth inning when he came home to score on a wild pitch, sending the game to extra innings.
In extras, after a scoreless 10th inning, hits to rising stars Ronald Acuna Jr and Michael Harris II drove in a run each, and the Phillies were only able to claw one back.
Braves reliever Jackson Stephens was credited with the win after pitching both extra innings, striking out three batters and allowing one unearned run.
Trout goes deep in Angels win
Trout, who is now tied for the fourth-most home runs in the league with 37, finished three-for-four at the plate and scored three times, highlighted by a 416-foot bomb to left-field.
Fellow Angels star Shohei Ohtani also had a strong outing, collecting two hits and an RBI from five at-bats, while Jose Suarez took the win on the mound with two earned runs in five-and-two-thirds innings.
Javier pitches a gem for the Astros
Javier had a perfect game through four-and-a-third innings before allowing his sole hit of the contest, quickly following it with a double-play to end the inning. That hit was the only baserunner he allowed as he also finished with no walks, and he lowered his ERA for the season down to 2.65.
The Astros are the only team with three starting pitchers who all boast ERAs under 2.70, with American League Cy Young Award favourite Justin Verlander leading the league at 1.82, while the league-leader in quality starts, Framber Valdez, is at 2.69.
