Orioles power past Nats

BALTIMORE — Trey Mancini capped a three-homer binge in the first inning against Gio Gonzalez, and the Baltimore Orioles beat the Washington Nationals 6-4 on Monday night for their season-high fifth straight victory.

Kevin Gausman limited baseball’s most potent offense to two runs over seven innings. He retired the first 10 batters and struck out eight in his longest outing of the year.

Joey Rickard hit a leadoff homer and Mark Trumbo added a solo shot before Mancini connected with a runner on to make it 4-0. The early lead held up for the Orioles, who now hold a 37-24 advantage over their neighboring rivals in the so-called “Beltway Series,” which began in 2006.

Bryce Harper hit his 10th homer and drove in two runs for the Nationals.

YANKEES 10, REDS 4: Brett Gardner and Matt Holliday homered, and Masahiro Tanaka won his fifth consecutive start as New York shook off a long game and a short night’s sleep to beat host Cincinnati for its sixth victory in a row. The Yankees have the best record in the majors at 21-9 and are 12 games over .500 for the first time since the end of the 2015 season.

METS 4, GIANTS 3: Neil Walker hit a game-ending single with two outs in the ninth inning, and New York beat visiting San Francisco. Michael Conforto scored for New York’s first walkoff win this season, giving the Mets their seventh victory in 10 games.

CARDINALS 9, MARLINS 4: St. Louis ace Carlos Martinez drove in four runs, compensating for the two homers he gave up to Marcell Ozuna and leading the Cardinals over host Miami for their season-best fourth straight win.

BLUE JAYS 4, INDIANS 2: Marcus Stroman pitched six shutout innings, Kevin Pillar made a sensational catch in center field, and host Toronto topped Cleveland.

ROYALS 7, RAYS 3: Nate Karns struck out 10 while pitching into the seventh, Eric Hosmer had three hits, and Kansas City busted out of an offensive slump to win at Tampa Bay.
