LOS ANGELES — Shohei Ohtani reached 30 homers for the fifth straight season, hitting a fourth-inning drive after fouling a pitch off the plate umpire, and the Los Angeles Dodgers beat the Chicago White Sox 6-1 on Tuesday night.

Ohtani fouled the ball off Alan Porter’s right knee in the fourth. Ohtani checked on the umpire and stood by watching until Parker got up under his own power. The three-time MVP then hit a 408-foot shot to center, snapping an 0-for-6 skid and extending the lead to 6-1. He tied Cody Bellinger in 2019 for most home runs before the All-Star break in Dodgers history; Bellinger won National League MVP that year.

Ohtani joined Seattle’s Cal Raleigh (33) and Aaron Judge of the Yankees (30) as players with at least 30 homers by the All-Star break. It’s his third season with 30 homers before the break, tying Ken Griffey Jr. for third most in MLB history. (Judge and Mark McGwire each did so for four seasons.)

During the seventh-inning stretch, Ohtani walked over and checked on Porter again before leading off.

Los Angeles scored its most runs this season in support of Yoshinobu Yamamoto (8-6), staking the Japanese right-hander to a 4-0 lead in the first inning.

The Dodgers won for the 13th time in 16 games and opened a season-high, eight-game NL West lead. They are 16-5 (.762 win percentage) since June 8, the best record in MLB during that span.

Every run Tuesday night was scored with two outs.

Yamamoto allowed one run and three hits in seven innings, struck out eight and walked one.

White Sox rookie Shane Smith (3-6) got two quick outs in the first before walking Will Smith and Max Muncy back-to-back. Teoscar Hernández followed with an RBI single, Andy Pages hit a run-scoring double and Michael Conforto had a two-run single.

Chicago’s lone run came on Lenyn Sosa’s RBI single in the third.
