SEATTLE (AP) — Luis Castillo struck out 10 in six crisp innings, and the Seattle Mariners beat the Pittsburgh Pirates 5-0 on Saturday.

Castillo allowed one hit — Tucupita Marcano's double on the game's first pitch — and walked two. The right-hander earned his second straight win since dropping consecutive starts.

Gabe Speier, Matt Brash, Trevor Gott and Justin Topa then combined for three innings of one-hit ball for Seattle.

The Mariners backed Castillo (4-2) with three runs in the first and one in the second. Ty France hit an RBI double and scored on Eugenio Suárez's check-swing bloop single. Julio Rodríguez added a run-scoring double in the second.

Pittsburgh right-hander Vince Velasquez departed after two innings due to discomfort in his pitching elbow. He allowed seven hits and walked one.

The 30-year-old Velasquez also exited with elbow discomfort in his previous start on May 4, when he lasted just three innings against Tampa Bay. He was on the 15-day injured list prior to being activated for Saturday’s start.

J.P. Crawford, France and Rodríguez each had two hits for Seattle. It was Rodríguez's fifth multihit performance in the past six games.

Roster move

Pittsburgh designated right-hander Duane Underwood Jr. for assignment to make room for Velasquez. Underwood posted a 5.18 ERA in 24 1/3 innings across 20 relief appearances this season. He had a strong April, but struggled to an 8.44 ERA in May.

Up next

Pirates: RHP Luis Ortiz (1-2, 4.02 ERA) makes his fourth start of the season on Sunday after opening the year in Triple-A Indianapolis. He pitched 7 2/3 strong innings against Texas in his last outing, allowing just two runs and five hits.

Mariners: LHP Marco Gonzales (4-1, 5.68 ERA) takes the mound. He tossed six innings of two-run ball against Oakland in his last start, rebounding from a May 17 outing in Boston that was among the worst of his career.
