Mariners Seeking to Earn First Berth in Fall Classic
Seattle dropped Games 3 and 4 at home before rallying late to win Game 5 and take a 3-2 series advantage heading back east. The Mariners need to win just one of two games in a venue where they prevailed twice already in this series to earn their first appearance in the World Series in franchise history. Against Toronto at home in Game 5 Friday night, Seattle finished with five hits as Cal Raleigh (run, RBI) and Eugenio Suarez (two runs, five RBI) each had a pair in the contest. Suarez (his second and third) homered twice, including a tie-breaking grand slam in the eighth inning, while Raleigh (his fourth) also went deep in the win. Bryce Miller threw four innings, allowing one run on four hits with two walks and four strikeouts, but didn’t factor in the decision. Gabe Speier (1-1) earned the win as he threw a 1-2-3 eighth inning. Logan Gilbert was the starter for the Mariners in Game 6 Sunday night and struggled, allowing four earned runs (two homers ) in four innings. The bullpen was solid, allwoing just one run and four hits in four innings, but it wasn't enough. .
George Kirby gets the call here. He was 11-8 with a 4.21 ERA, a 1.185 WHIP, 46 walks and 162 strikeouts over 126 innings this season in the regular season.
