LOS ANGELES (Interstat) — Justin Wrobleski struck out nine over seven dominant innings, yielding only one hit, and the Los Angeles Dodgers defeated the Philadelphia Phillies 4-2 on Friday night at Dodger Stadium.

The Dodgers struck early, building a lead with four solo home runs, while Wrobleski allowed just a single run before the bullpen closed the door. The win improved the Dodgers to 37-20, while the Phillies fell to 29-28.

Wrobleski, who improved to 7-2, retired the first eight batters he faced before Phillies catcher J.T. Realmuto grounded out to end the second inning. The left-hander did not allow a hit until the sixth inning, when Kyle Schwarber led off with a solo home run to center field, his 22nd of the season. That was the only hit off Wrobleski, who walked none and struck out nine while throwing 88 pitches.

The Dodgers’ offense gave Wrobleski all the support he needed in the early innings. Freddie Freeman opened the scoring in the bottom of the first with a solo home run to left field, his eighth of the season, off Phillies starter Zack Wheeler. Max Muncy followed with a solo shot to right-center in the second, his 13th, tying the game at 2-2 after the Phillies had failed to score in the top half.

Shohei Ohtani put the Dodgers ahead for good in the third inning with a solo home run to right field, his 10th. Will Smith added another solo blast in the fifth, his sixth, extending the lead to 4-1.

Wheeler, who took the loss to fall to 4-1, lasted four innings. The right-hander allowed four runs on four hits and one walk while striking out six. He surrendered the four solo homers, but settled down after the second inning until Smith connected in the fifth.

The Phillies managed only three hits in the game. After Schwarber’s homer in the sixth, Philadelphia added a second run in the eighth. With one out, Brandon Marsh doubled to center off Dodgers reliever Edgardo Henriquez. Marsh advanced to third on a groundout by Adolis García, then scored on a single to center by Steward Berroa. Henriquez was replaced by Tanner Scott, who got Kyle Schwarber to strike out swinging to end the inning.

Scott, who earned his fifth save, worked a perfect ninth inning, striking out one. He retired Trea Turner on a flyout, Bryce Harper on a strikeout, and Alec Bohm on a flyout to right field to seal the victory.

The Dodgers finished with six hits, including a 3-for-4 performance from Ohtani, who also singled in the fifth and the eighth. Freeman and Muncy each had one hit, both homers. Smith also went deep. Mookie Betts, playing shortstop, went 0 for 3 with two strikeouts. Kyle Tucker went 0 for 3 with a strikeout. Alex Call walked once in two plate appearances. Alex Freeland went 0 for 2. Miguel Rojas, who pinch-hit in the eighth, popped out.

For the Phillies, Schwarber went 1 for 4 with the home run and two strikeouts. Berroa went 1 for 4 with an RBI single. Marsh went 1 for 4 with a double. Trea Turner reached on an error in the fourth but went 0 for 4 overall with two strikeouts. Bryce Harper struck out three times in four at-bats. Alec Bohm, Bryson Stott, J.T. Realmuto, Adolis García and Brandon Marsh combined to go 1 for 22.

The game lasted 2 hours, 3 minutes before an announced crowd of 50,834.

The Dodgers’ bullpen held the Phillies after Wrobleski’s exit. Henriquez allowed two hits and one run in two-thirds of an inning, but Scott shut the door. Tim Mayza pitched a scoreless seventh inning for Philadelphia, allowing no hits and striking out two.

The Phillies had won their previous three games, all by shutout in San Diego, before dropping this series opener. The Dodgers had won four of their last five, including a series win against the Colorado Rockies.

Schwarber’s sixth-inning homer was the only hit off Wrobleski, who had allowed just one earned run in his previous three starts combined. The Phillies had no other baserunners reach scoring position until the eighth.

The Dodgers’ four solo home runs marked the seventh time this season they have hit at least four homers in a game. The win was the Dodgers’ 14th in their last 18 games at Dodger Stadium.

The two teams will continue the three-game series Saturday night. The Phillies will send a starter to the mound looking to even the series, while the Dodgers will aim for a second straight win.
