Following a 9-8, 10-inning win for Boston in the opener last night, the Mariners (64-74) and the Red Sox (75-63) continue their three-game series tonight at Fenway.
Seattle appeared poised to steal the opener after battling back and generating offense throughout the night. The Mariners totaled 11 hits receiving contributions up and down the lineup. The Sox got one more hit and ultimately, one more run. They forced extra innings with two runs in the eighth on a Trevor Story double and one in the ninth on a sac fly from Ceddanne Rafaela before Story again picked up a big hit in the tenth, a single to center, driving in Eli White to win it for the Red Sox. Aroldis Chapman picked up the win. Randy Arozarena and Cal Raleigh went yard for the Mariners, but it was not enough.
Seattle closed the month of August with five straight losses and now sit six games behind the Astros in the AL West and 5.5 games behind the Guardians for the final Wild Card spot. The Red Sox snapped a brief two-game losing streak with the win to pull within three games of the Yankees and the top Wild Card spot in the American League.
Seattle looks to snap the skid with right-hander Bryan Woo (9-9, 4.36 ERA) on the bump. Woo's most recent outing came August 26 against Philadelphia, and it was one of his rougher starts of the year. The Phillies tagged him for six earned runs on five hits over four innings, including a pair of home runs. He struck out five but was unable to work deep into the game as Seattle lost 6-0. The righthander fared far better in his previous two starts. He allowed two runs in six innings at Houston on August 16 and threw five scoreless innings at Yankee Stadium on August 11. The Red Sox have yet to announce their starter for tonight. It was Sonny Gray’s (16-4, 2.79 ERA) turn to take the ball but Boston earlier announced they planned to give him an extra day of rest.
