Erick Fedde threw the first complete game of his career and William Contreras drove in three runs, as the visiting St. Louis Cardinals posted a 10-0 victory over the Washington Nationals on Friday.

Fedde (3-3) allowed six hits, while striking out eight and walking none across 109 pitches, marking the fourth complete game thrown in the majors this season. Nolan Arenado had three hits, while Ivan Herrera drove in a pair of runs for the Cardinals, who extended their winning streak to six games.

Mitchell Parker (3-3) allowed four runs on seven hits in his four-inning stint for Washington, also tallying five strikeouts and two walks. CJ Abrams had three of the Nationals’ six hits, as the club dropped its third straight game. Washington’s pitching staff has surrendered 27 runs across the three defeats.

After Parker walked Lars Nootbaar and Masyn Winn to begin the game, Arenado laced a one-out single to load the bases, before Contreras doubled in a pair of runs to give St. Louis the early advantage.

Brendan Donovan’s double and Arenado’s single began the top of the third, followed by Herrera’s one-out sac fly to extend the Cardinals’ lead to 3-0.

St. Louis tacked on in the fourth, as Pedro Pages doubled and advanced to third on Parker’s wild pitch, then scoring on Victor Scott II’s sac fly.

Replacing Parker in the fifth was Jackson Rutledge, who was met with Arenado and Contreras’ singles, followed by Herrera’s RBI double and Jordan Walker’s sacrifice fly, pushing the Cardinals’ lead to 6-0.

Lucas Sims relieved Rutledge in the eighth, hitting Walker with a pitch before walking Pages and Scott to load the bases. Winn singled in Walker with one out and Sims’ subsequent wild pitch gave the Cardinals an 8-0 lead. After walking Donovan and retiring Arenado, Sims walked Contreras to bring in the ninth St. Louis run.

The tenth and final Cardinals run came in the top of the ninth off Andrew Chafin, who walked Walker and Pages before CJ Abrams’ throwing error allowed Walker to score.
