WASHINGTON (AP) — Yoshinobu Yamamoto pitched six shutout innings, and the Los Angeles Dodgers defeated the Washington Nationals 2-1 on Thursday to complete a three-game sweep.

Teoscar Hernández homered for the Dodgers, who matched a season high with four straight wins.

Joey Meneses had three hits for Washington, which was swept for the first time this season. The Nationals scored four runs in the series and went 4 for 20 with runners in scoring position.

Los Angeles designated hitter Shohei Ohtani was 0 for 4, stopping a nine-game hitting streak and dropping his batting average from a major league-leading .371 to .358.

Yamamoto (2-1) didn’t allow a runner past second and allowed four hits and a walk while striking out seven. He had multiple runners on only in the sixth, when he gave up a pair of two-out singles before Keibert Ruiz’s inning-ending groundout.
