WASHINGTON — Yan Gomes connected for a grand slam and Trea Turner got four hits, leading Patrick Corbin and the Washington Nationals over the Pittsburgh Pirates 8-1 on Tuesday night.

The Nationals won their third in a row and sent Pittsburgh to its ninth straight loss.

Corbin (4-5) pitched 8 1/3 innings, allowing one run and eight hits. He struck out seven and walked one while going at least eight innings for the first time since Aug. 21, 2019.

Gomes’ slam finished a five-run first inning against Tyler Anderson (3-7). It was Gomes’ first grand slam since joining the Nationals in 2019 and the fourth of his career.

Kyle Schwarber led off the bottom of the first with one of three consecutive singles by the Nationals to start the inning. Ryan Zimmerman struck out with the bases loaded before Josh Harrison hit an RBI single and Gomes followed with his home run to left field.

The Nationals entered the game with a league-worst .460 OPS with the bases loaded this season. They’d hit one other grand slam — Josh Harrison against Baltimore — before Gomes connected.
