The Colorado Rockies completed a rare sweep of the San Francisco Giants in MLB, while the Detroit Tigers had a big win.
The Rockies, who have never won the National League (NL) West since joining MLB in 1993, sit on top of the division following a three-game sweep of the reeling Giants.
It was Colorado's first sweep of the Giants at Coors Field since May 2002 and came on the back of seven strong innings from Kyle Freeland in an 8-0 shut-out win on Sunday.
The Tigers also did it easily, crushing the Minnesota Twins 13-4 thanks to a fine performance from John Hicks.
The Cincinnati Reds overcame the Chicago Cubs 7-5, the Houston Astros had a 10-inning 6-4 win over the Tampa Bay Rays and the Philadelphia Phillies beat the Atlanta Braves 5-2.
The Pittsburgh Pirates edged the New York Yankees 2-1, the Boston Red Sox beat the Baltimore Orioles 6-2 and the Chicago White Sox were 6-2 winners against the Cleveland Indians.
The St Louis Cardinals had a 6-4 win against the Milwaukee Brewers, the Texas Rangers beat the Kansas City Royals 5-2, the Toronto Blue Jays claimed a 6-2 victory over the Los Angeles Angels and the Oakland Athletics were thrashed 11-1 by the Seattle Mariners.
The Los Angeles Dodgers beat the Arizona Diamondbacks 6-2, the Miami Marlins got past the San Diego Padres 7-3 and the Washington Nationals claimed a 6-3 win over the New York Mets.
Hicks went three-for-five with five RBIs in Detroit's win over the Twins. Hicks completed the victory with a three-run homer in the top of the ninth.
Blue Jays center fielder Kevin Pillar robbed Angels right fielder Kole Calhoun of extra bases in the eighth inning of Toronto's victory.
A's center fielder Jaff Decker was 0-for-four with three strikeouts in the leadoff spot. Matching his line was Brewers first baseman Jesus Aguilar, who went hitless in Milwaukee's loss to the Cardinals.
IN-FORM NATIONALS, ROCKIES MEET
It is a pretty tough turnaround for the Nats (12-5), who were in New York Sunday and have to fly to Denver. There could be plenty of fireworks as the teams open a four-game series at Coors Field with each club capable of launching the ball into the stratosphere. Trying to prevent that will be Rockies (13-6) lefty Tyler Anderson (1-3, 7.32 ERA) against Nationals rookie Jacob Turner, who will make a spot start after getting called up to replace Stephen Strasburg, who misses a start while on paternity leave.
