BOSTON (AP) Jorge Polanco homered in the fourth inning and added an RBI double in the sixth, Dylan Moore drove in three with a bases-loaded double in a five-run fifth, and the Mariners beat the Boston Red Sox 10-6 on Tuesday night. An eight-run outburst midway through the game helped Seattle win for the fourth time in five games as the Mariners capitalized on some defensive gaffes that had Boston fans booing. Really excited about our offense. The guys are really starting to come together, said Mariners manager Scott Servais, whose club Austin Riley Jersey has won four of five and avenged on Monday night. The Mariners have scored six or more runs in each of their last five games, outscoring opponents 39-26 during that stretch. Seattle starter Luis Castillo (9-10) pitched six innings, holding Boston to three runs on six hits and a walk. He struck out three. Yesterday I felt like we were punched a lot. But tonight, most of the guys came in with the mentality Its not going to stay like that, Castillo said through a translator. Rafael Devers hit a three-run homer for Boston in the third. The Red Sox added three more runs in the seventh, but could not complete a comeback from a 10-3 deficit. The Red Sox made three errors, including two in the fifth, when the Mariners chased starter James Paxton (8-3), and another in the sixth. Paxton, picked up by Boston in a , pitched 4 1/3 innings, allowing six runs on six hits and striking out five. Obviously we didnt play defense behind him, Boston manager Alex Cora said. The Mariners had 11 at-bats in the fifth. A throwing error by first baseman Dominic Smith followed by a fielders choice loaded the bases for Seattle. Shortstop Ceddanne Rafaela pulled Smith off the bag and allowed Randy Arozarena to reach on a fielders choice after a succe sful challenge by the Mariners overturned the original call. Justin Turner drove in a run with a fielders choice, Polanco drew a walk and then Moore hit a double off reliever Zack Kelly off of the Green Monster to clear the bases for three more runs. Weve had two consistent nights of offense, which is great, said Moore, who went 2 for 3 and reached base four times. Reliever Yohan Ramrez allowed a run to score on a wild pitch in the sixth, then Ramrez hit Mitch Garver. Garver stole second and when Boston catcher Connor Wongs throw bounced into center field Polanco scored. Turner made his debut for the Mariners one day after Seattle . Turner, who spent last season with the Red Sox, drove in a pair of runs and Arozarena, who just joined Seattle over the weekend after a trade with Tampa Bay, also drove in a run. This ballpark, as hitter friendly as it is, youre going to outscore them certain nights and thats what we did, Servais said. A lot of good things offensively. Its been a really good road trip for us offensively, so credit to our guys. Were starting to get some rhythm going there. TRAINERS ROOM` Mariners: CF Victor Robles left the game in the eighth with what Servais described as a hip i sue that will keep him out of the lineup Wednesday. Its hard to take him out, but weve got to do whats best for him, Servais said. Red Sox: SS Ceddanne Rafaela spent a few minutes with trainers after getting hit by a pitch in the bottom of the fifth. He remained in the game. UP NEXT RHP George Kirby (8-7, 5.37 ERA) tries to help the Mariners clinch the series with a start Wednesday night against RHP Brayan Bello (10-5, 5.27) for the Red Sox. This story has been corrected to show that Polanco had an RBI double in the sixth, not in the fifth; and Dylan Moore drove in three with a bases-loaded double in the fifth, not a single in the sixth.
