Landen Roupp pitched six-plus innings and the visiting San Francisco Giants ended the Washington Nationals’ five-game winning streak with a 4-0 win on Friday night.

Roupp (3-3) allowed five hits and two walks while striking out two. He left after the first two Nationals reached in the seventh.

Jung Hoo Lee reached base three times on two hits and a walk and scored twice for the Giants.

Nationals starter MacKenzie Gore left with no outs and a runner on first in the seventh inning. He grimaced after throwing a pitch to Matt Chapman. Manager Dave Martinez and the trainer came out, and after a brief discussion, Gore left the game.

Gore (2-5) was charged with a run on two hits. He struck out nine and walked three.

Nationals outfielder Daylen Lile went 1-for-2 in his major league debut. The 22-year-old, Washington’s second-round pick in the 2021 draft, was called up Friday after outfielder Jacob Young (left shoulder AC sprain) was put on the 10-day injured list.

Lee led off the Giants’ fourth with a single. With one out, he attempted to steal. Wilmer Flores struck out on the pitch and Lee was called out due to batter interference by Flores.

Jose Tena doubled with one out in the Nationals’ fifth but was picked off with two outs.

Lee walked against Gore leading off the seventh. After Gore departed, Chapman walked against Jackson Rutledge. Flores grounded into a double play, but Lee went to third and scored on Willy Adames’ single up the middle to make it 1-0.

Rutledge then issued three consecutive walks, the last one to Patrick Bailey forcing in a second run.

Luis Garcia Jr. doubled leading off the seventh for Washington and Josh Bell walked. Randy Rodriguez replaced Roupp, struck out Robert Hassell III and got Tena to ground into a double play.

Lee, Chapman and Flores singled with one out in the eighth to make it 3-0 and another run scored on a wild pitch by Andrew Chafin.
