BOSTON (AP) — Mookie Betts hit three home runs against James Paxton during the first four innings Friday night in the Boston Red Sox's 10-5 victory over the New York Yankees, whose starting pitchers have stumbled this week in historic fashion.Betts homered on Paxton's eighth pitch in a three-run first that included J.D. Martinez's two-run homer, went deep again leading off the third for a 4-0 lead and hit a two-run drive in the fourth for a 7-0 advantage.Betts added an RBI double in the sixth off David Hale to give him five RBIs and grounded out in the eighth. With his fifth career three-homer game, Betts raised his season total to 18 homers.Batters have had three-homer games on four straight days for the first time in big league history. Betts followed the New York Mets' Robinson Canó, St. Louis' Paul DeJong and Minnesota's Nelson Cruz.Andrew Cashner (10-5), coming off losses in his first two starts after Boston acquired him from Baltimore, allowed three runs and 10 hits in 6 2/3 innings.Martinez had three RBIs for the Red Sox, who won the opener of the four-game series 19-3 and have pulled within nine games of the AL East-leading Yankees.Paxton (5-6) became just the fourth pitcher in big league history to allow a leadoff home run in three straight starts, according to STATS, after Brad Radke (2004), Brandon Backe (2008) and Yovani Gallardo (2017).DODGERS 4, NATIONALS 2WASHINGTON (AP) — Justin Turner hit a two-out, three-run homer in the eighth inning to lift Los Angeles over Washington in the opener of a three-game series.After the Nationals had retired 22 straight batters, reliever Tony Sipp (1-2) walked Joc Pederson and then gave up a single to Alex Verdugo before exiting with two outs in the eighth. Kyle Barraclough, who was recalled earlier on Friday from Double-A, came in and immediately gave up the Turner blast to center field. Turner has 15 homers this season.Joe Kelly (4-3) retired Anthony Rendon to end the seventh while Kenley Jansen walked home a run before striking out Howie Kendrick with the bases loaded in the bottom of the ninth to earn his 25th save of the season.Nationals starter Aníbal Sánchez retired the final 20 batters he faced. Sánchez struck out six, while allowing one run on three hits.Dodgers starter Hyun-Jin Ryu allowed eight hits and one earned run in 6 2/3 innings.METS 6, PIRATES 3NEW YORK (AP) - Trade candidate Zack Wheeler showed off a live arm in his return from the injured list, Jeff McNeil hit the first of four Mets homers and New York beat slumping Pittsburgh.Wheeler (7-6) struck out seven over 5 1/3 innings in his first start since July 7 due to right shoulder fatigue — an issue he called an impingement. With contending teams watching closely, the right-hander averaged 96.8 mph on his fastball and looked sharp until Adam Frazier clocked a two-run homer in the sixth inning. Wheeler allowed three runs, six hits and no walks.McNeil hit a three-run homer, and Todd Frazier, Pete Alonso and Wilson Ramos added solo shots for the Mets.

Greinke allowed a first-inning run before retiring 11 consecutive batters. The right-hander went six innings and scattered four hits, struck out five and walked one. He is 7-0 in his career against the Marlins.Jose Quijada (1-3) pitched a scoreless ninth for the win.___More AP MLB: https://apnews.com/MLB and https://twitter.com/AP_Sports
