The Red Sox swept a series for just the fourth time this year, the first since May 10-12 against the Chicago White Sox. The World Series champions are 27-16 following a 6-13 start and face the second-place Rays in a four-game weekend series at Fenway Park.“We have some confidence going against a really good ballclub,” Betts said. “Ride the wave through this weekend.”Kansas City has lost six straight and nine of 10, dropping to a big league-worst 19-43.With a doubleheader coming up Saturday against Tampa Bay, Boston gave Ryan Weber his third start. He allowed two runs and five hits in 1 1/3 innings, and Colten Brewer (1-2) followed with two scoreless innings of two-hit relief.Matt Barnes, Boston’s seventh pitcher, allowed Jorge Soler’s one-out RBI double in the ninth but got his fourth save in seven chances by striking out Ryan O’Hearn and Chelsor Cuthbert.Duffy allowed four runs and four hits in 2 1/3 innings. Eduardo Núñez’s hard drive went off the inside of Duffy’s right kneecap and ricocheted to O’Hearn, who tagged Núñez for the final out of the second. Duffy retired one of six batters he faced in the third.“It’s sore, but it didn’t affect me Dennis Eckersley Jersey ,” Duffy said. “If I go back out there it’s because I can. If I can, there are no excuses.”Betts’ 10th home run tied the score, and Rafael Devers put Boston ahead with a two-run single.Soler’s fifth-inning homer cut the deficit to 4-3, but Christian Vázquez hit a two-run triple in the seventh and scored on Scott Barlow’s wild pitch.Cuthbert and Alex Gordon homered for the Royals.TRAINER’S ROOMRed Sox DH J.D.

DENVER (AP) — Trevor Story boiled down his power surge to one concise reason.“Not trying to do too much,” he explained.And yet he’s doing plenty.Article continues below ...Story hit a pair of two-run homers as part of a career-high seven-RBI night and the Colorado Rockies beat the slumping Toronto Blue Jays 13-6 on Friday for their sixth straight win.It was the 13th career multi-homer game for Story, whose 15 homers tied him with J.J. Hardy (2007) for the most by an NL shortstop before June in a single season, according to the Rockies.Story also had a three-run double, walked and scored four times. Nolan Arenado added three hits, including two doubles Santiago Casilla Jersey , and three RBIs. Arenado batted .425 in May.“We do have a good lineup,” said manager Bud Black, whose team’s 183 runs in May is tied for the fourth-most for a month in team history. “I think it’s deep. It has speed. It has power. It has average.”Rockies starter German Marquez (6-2) proved just as difficult at the plate as on the mound. He lined two singles in extending his hitting streak to five games, which is the longest by a Rockies pitcher since Mike Hampton hit safely in eight straight in 2002.On the mound, Marquez allowed two runs and struck out seven over seven efficient innings.“Great job by Marquez,” Story said. “We lean on him and have a lot of confidence in him.”For a change, Colorado didn’t have to fret late in the game after jumping out to an early 10-2 lead. The Rockies have four walk-off wins in going 7-1 so far on this season-high, 10-game homestand.“It’s been nail-biters the past week or so,” Story said. “It’s nice to have a big lead early.”Edwin Jackson (0-3) absorbed a majority of the damage. The veteran right-hander tied a career high by allowing 10 earned runs in lasting just 2 1/3 innings. Jackson remains winless in four starts with his 14th different team after being acquired in a trade with Oakland on May 11.“It has been a while since I’ve been in a stretch like this. You lose confidence in periods like this,” Jackson said. “I still know what I am capable of doing. It’s a matter of doing what I can do, but I haven’t been doing it the last few starts.”Vladimir Guerrero Jr. hit a solo homer in the eighth during a four-run inning. Randal Grichuk had a solo shot in the second for the Blue Jays, who’ve dropped eight of their last nine games.TRAINER’S ROOMBlue Jays: RHP Aaron Sanchez is on track to start Sunday.

The team moved to New Orleans after the ’92 season as the Rockies arrived in town.“I remember that as a hitter when I played for the Zephyrs, I hit home runs here,” Montoyo cracked.HOT CORNERArenado made to two plays at third with his bare hand, including one in the second when he ranged to his right and threw across his body to get Freddy Galvis and end the inning.“At times, we take Nolan for granted, the plays he makes,” Black said. “You don’t see other guys doing it as consistently as he does.”THIS & THATRockies lefty Kyle Freeland was sent to Triple-A Albuquerque to work on his mechanics.
