MILWAUKEE — Garrett Mitchell and Gary Sánchez each hit two-run doubles during a six-run first inning, and the MLB-best Milwaukee Brewers beat the Seattle Mariners 7-4 on Thursday.

Mitchell also homered in the eighth, finishing 3 for 4 with three RBIs as Milwaukee took two of three from Seattle. The series included the Brewers' 22-0 win on Tuesday night that matched the record for the biggest shutout in baseball’s modern era. Milwaukee has won seven straight home series.

George Kirby (8-10) had a nightmarish first inning, walking the leadoff batter and giving up six hits. Sánchez got the Brewers on the board and Joey Ortiz added an RBI single. Mitchell's double made it 5-0 and David Hamilton drove in the last run with another double.

Kirby worked 3 1/3 innings, allowing six runs on nine hits.

Staked to the big lead, Brewers starter Robert Gasser lasted just 3 2/3 innings and was lifted mid-at-bat by manager Pat Murphy after falling behind in the count to Randy Arozarena. Gasser gave up four hits and four runs.

Brendan Donovan had a two-run double for Seattle, and Dominic Canzone's RBI single got the Mariners within 6-4 in the fourth.

Chad Patrick (7-4) pitched 2 1/3 scoreless innings in relief. Trevor Megill retired the side in order in the ninth for his 23rd save in 25 opportunities.
