In the fifth inning, he made a good opening statement.
Schierholtz hit a solo home run into right off Edwin Jackson to give the Phillies a 3-2 lead.
His home run would prove to be the game winner.
Vance Worley (6-6) pitched in a solid outing, only allowing two runs to the Nationals and seven hits.
Then Charlie Manuel elected to use three relievers in the eighth inning.
The first was Antonio Bastardo, who got Bryce Harper to fly out to right.
Then Josh Lindblom made his debut for the Phillies after being traded by the Dodgers for Shane Victorino.
Lindblom allowed a hit to Ryan Zimmerman (pinch hitting for third baseman Chad Tracy), but struck out Michael Morse in the next at-bat for the second out.
Jeremy Horst was the third reliever used in the inning.
With two outs and Ryan Zimmerman still on first, Zimmerman tried to steal second, but was thrown out by Erik Kratz, who was filling in for Carlos Ruiz behind the plate.
In the ninth, Jonathan Papelbon came in to close the game for the Phillies.
Papelbon threw a one-two-three inning, getting Roger Bernadina to strike out swinging for the final out, for his 23rd save of the season.
The Phillies found themselves down 2-0 after the first inning.
With the bases loaded due to a fielding error by Kevin Frandsen, Adam LaRoche singled to score Bryce Harper for the Nationals' first run of the game.
Then Danny Espinosa grounded into a fielder's choice that was misplayed by Chase Utley, which kept it from being turned for a double play. Chad Tracy scored from third on the play to make it 2-0 Washington.
Jimmy Rollins tied the game though with two solo home-runs.
The first came in the third to make it 2-1.
Then Rollins hit the second in the at-bat before Schierholtz would give the Phillies the lead with his home run in the fifth.
The Phillies have now won two straight against the NL East leading Nationals.
Cole Hamels will take the mound on Thursday night for the Phillies, as they try to go for a sweep.
