ST. LOUIS (AP) — Koda Glover rewarded his manager’s faith.

Bryce Harper had three hits and drove in three runs, Glover earned the save in the first opportunity since Ryan Madson was placed on the disabled list, and the Washington Nationals snapped a four-game losing streak with a 5-4 victory over the St. Louis Cardinals on Thursday night.

The Nationals won for just the third time in their last 10 games and snapped the Cardinals’ season-high, eight-game winning streak.

Tanner Roark (8-12) gave up four runs, three earned, in six innings.

A beleaguered bullpen that had blown two leads to start the losing streak took care of the rest. Justin Miller pitched two scoreless innings before Glover closed it out.

Glover took the loss in the series opener on Monday, giving up a game-ending homer to Paul DeJong.

Harper drove in the game’s first run with a double in the first and knocked in two more with a bases-loaded single in the fourth to give the Nationals a 4-1 lead.

A pair of errors helped the Nationals extend their lead to 5-1 in the fifth. St. Louis committed three errors in the game after committing just four total errors during the winning streak.

The Nationals had opportunities to pad the lead, leaving the bases loaded in the third and fifth while stranding nine runners in the first five innings.

The Cardinals got within one in the sixth. After DeJong and Kolten Wong came up with back-to-back, two-out RBI hits, Harrison Bader hit a slow grounder to third. Anthony Rendon’s throw to first got away from Ryan Zimmerman for an error, allowing Wong to score from second to cut the Nationals’ lead to 5-4.

Just two of the four runs Luke Weaver (6-11) allowed in his 3 2/3 innings were earned. He gave up seven hits, including two to Roark, who scored both times.

Tyson Ross allowed one unearned run in 3 1/3 innings of relief.

Bader homered in the third and Matt Carpenter walked twice to extend his on-base streak to a career-high 34 games.
