Johan Oviedo recorded his first career shutout and Ke'Bryan Hayes went 4-for-4 with a walk and an RBI as the visiting Pittsburgh Pirates opened a three-game series against the Kansas City Royals with a 5-0 win on Monday.

Oviedo (8-13) allowed two hits with two walks and five strikeouts while throwing a career-high 112 pitches for Pittsburgh, which snapped a two-game skid. He tossed a complete game for the first time in his 53rd career start.

Kansas City lost for the eighth time in nine games and fell a season-high 51 games under .500. The game was completed in a crisp 2 hours, 16 minutes.

The Pirates claimed an early lead against Zack Greinke (1-13), who allowed the first three batters he faced in the second inning to reach base safely. Alfonso Rivas followed with a double-play grounder that scored Endy Rodriguez.

Pittsburgh tacked on a run in the third on consecutive doubles by Ji Hwan Bae and Hayes to begin the inning. Hayes has a team-high 18 RBIs this month, in 23 games.

Greinke made his second appearance since returning from the injured list, and he gave up two runs on six hits over 4 2/3 innings. He walked two and struck out two.

The Pirates extended their lead with two outs in the seventh inning on back-to-back RBI singles by Andrew McCutchen and Joshua Palacios against Taylor Hearn.

Kansas City struggled to generate any offense against Oviedo, who won for the fifth time in his past seven starts. Hayes turned in the defensive play of the game in the sixth inning when he made a diving grab of Bobby Witt Jr.'s grounder to third and got a forceout at second.

Pittsburgh pushed another run across in the eighth inning against Jackson Kowar when Jack Suwinski hit a leadoff single and scored on Rivas' one-out double.

Kansas City's only two hits came on MJ Melendez's two-out single in the third and Drew Waters' leadoff single in the fifth.

Rivas and Bae had two hits apiece for Pittsburgh, which finished with 12 hits.
