PITTSBURGH -- Jose Quintana pitched six scoreless innings for his first win since 2019 and the first victory by a Pittsburgh starting pitcher this season as the Pirates beat the Los Angeles Dodgers 5-1 on Monday night.
The Pirates also ended a 16-game losing streak against the Dodgers dating to 2018 and snapped Los Angeles' six-game winning streak.
Quintana (1-1) allowed four hits and four walks while striking out five. His previous win came on Sept. 5, 2019, at Milwaukee while pitching for the Chicago Cubs.
The veteran left-hander has been plagued by injuries and ineffectiveness in recent seasons, going 20 starts and 42 appearances between victories.
"Huge," Quintana said. "It's tough to get hurt. I kept working hard. I knew this day would come one day. I'm really happy to get a win against a team like that. It's good. Just keep rolling. All the starters get confidence, and we can do it."
The Pirates finally got their first win from a starter in their 28th game, a major league record to begin a season. The old mark was set by the Baltimore Orioles in 1988 when they started 0-21.
Pittsburgh starters had been 0-10 this season, with their relievers collecting all 11 of their wins.
"You guys are more enamored about [the streak] than I am," Pittsburgh manager Derek Shelton said. "We just want to get wins, regardless of who gets the credit."
Pittsburgh's last victory over the Dodgers came on June 6, 2018. Los Angeles had also won 25 of the previous 27 games between the teams.
"It's baseball," Los Angeles manager Dave Roberts said. "They outhit us and they outpitched us tonight, and that's the ballgame. I thought Quintana was really good."
Julio Urias (2-2) allowed two runs in six-plus innings while scattering 11 hits. He struck out four and walked none.
Pittsburgh rookie Jack Suwinski hit his first career home run, a two-run shot to center field in the eighth inning off Robbie Erlin, to push the lead to 5-0. Michael Perez also connected for the Pirates.
"You think about it for a long time and it's still mind-blowing when it happens," Suwinski said with a smile.
Pinch-hitter Edwin Rios' leadoff home run in the ninth inning off David Bednar kept the NL West-leading Dodgers from being shut out for the first time this season.
The top six hitters in the order were a combined 13-for-23.
The Pirates opened the scoring in the fourth inning when Chavis lined a triple to center field and scored on Tsutsugo's sacrifice fly.
Perez led off the seventh with his homer, ending Urias' night. Chavis added a sac fly later in the inning.
The Dodgers put runners on first and second in the second, third and seventh innings but failed to capitalize. They left eight runners on base, though Mookie Betts extended his hitting streak to 10 games.
