Ohtani has 177 career homers. His previous longball on Sunday gave him the record for homers by a Japanese-born player in Major League Baseball, surpassing Hideki Matsui.

“Dangerous, very dangerous,” Dodgers manager Dave Roberts said of Ohtani before the game. “Any time he swings the bat he can hang the game and now being even more disciplined in the strike zone just makes him more scary.”

Outman, batting for Kiké Hernández, drilled a splitter from Hunter Harvey (1-1) to right field for a double in the eighth to score Teoscar Hernández from second and break a 1-1 tie. Rojas followed with a run-scoring single.

Dodgers starter James Paxton needed 89 pitches to get through 4 2/3 innings, scattering five hits and allowing one run.

Relievers Michael Grove, Alex Vesia (1-2), Daniel Hudson and Evan Phillips held Washington scoreless the rest of the way. Phillips worked out of a bases-loaded jam in the ninth for his sixth save.

Nationals starter Patrick Corbin, who allowed five runs in a 6-2 loss to the Dodgers a week ago, worked 5 1/3 scoreless innings, allowing three hits, three walks and striking out three on 86 pitches.

The Dodgers tied the game in sixth on an RBI single by Hernández.

Freddie Freeman went 2-for-4 with a single and a double. Rojas had two singles.

TRAINER’S ROOM

Dodgers: Roberts said RHP Blake Treinen (bruised lung) will need three to four rehab outings when he is healthy enough to pitch. Treinen’s first rehab game has not been announced. … OF Jason Heyward (lower back tightness) will join the team in Arizona around April 29. He has yet to swing a bat and Roberts expects a rehab assignment of four or five games.

Nationals: Placed LHP Robert Garcia (flu) on the 15-day injured list and called up RHP Jacob Barnes from Triple-A Rochester. … C Keibert Ruiz was sent to Double-A Harrisburg on a rehab assignment.

UP NEXT

The Dodgers send RHP Landon Knack (0-1, 3.60 ERA) to the mound against RHP Jake Irvin (1-1, 3.13) in a rematch of last Wednesday’s 2-0 Nationals win in Los Angeles.
