WASHINGTON (AP) — Christian Yelich hit his first career grand slam, Keon Broxton added a three-run homer, and the Milwaukee Brewers earned a series victory with a 9-4 victory over the Washington Nationals on Sunday.

Both Broxton and Yelich homered as part of a seven-run fifth inning. It matched Milwaukee’s highest-scoring inning of the season.

Washington starter Jefry Rodriguez (2-2) struggled with his control throughout his outing, walking seven while allowing seven runs in 4 2/3 innings. But he wasn’t hit hard until the fifth.

Rodriguez retired two of the first three batters that inning, but yielded a Manny Pina single and then Broxton’s blast to center.

Manager Dave Martinez pulled Rodriguez after another single and a walk, but reliever Tim Collins fared no better. His first six pitches were balls. Yelich hammered the seventh to left center for his 27th homer of the season to give Milwaukee a 9-4 advantage.
