Bryce Harper blasted yet another grand slam as the Washington Nationals crushed the Miami Marlins 7-0 in MLB on Tuesday.
Harper hit his second slam and seventh home run of the year as the Nationals improved to 10-3.
The Tampa Bay Rays had it far tougher, needing 10 innings to overcome the Boston Red Sox 3-0.
The New York Mets thrashed the Philadelphia Phillies 11-1 and the Atlanta Braves cruised past the Los Angeles Dodgers 8-1.
The Kansas City Royals were 8-6 winners over the Detroit Tigers, the Texas Rangers got the better of the Houston Astros 7-5 and the Chicago White Sox shut out the Los Angeles Angels 5-0.
The Oakland Athletics took 11 innings to get past the New York Yankees 3-2 and the Cincinnati Reds beat the Colorado Rockies 4-3.
The Chicago Cubs edged the St Louis Cardinals 2-1 and the Cleveland Indians beat the Seattle Mariners 3-2.
The Milwaukee Brewers overcame the Minnesota Twins 6-5 and the Toronto Blue Jays opened their series against the Baltimore Orioles with a 4-3 win.
Elsewhere, the Arizona Diamondbacks defeated the San Francisco Giants 3-0, while the San Diego Padres triumphed over the Pittsburgh Pirates 5-4.
SMYLY HOLDS RED SOX
Rays starting pitcher Drew Smyly threw eight shutout innings against the Red Sox. Smyly was forced to accept a tough-luck no-decision, but he certainly did enough to win, striking out 11 batters and giving up just one hit.
Indians shortstop Francisco Lindor flashed his defensive skill in his team's win.
REDS STEAL AGAIN AND AGAIN AND AGAIN
The Reds stole five bases in the second inning of their win against the Rockies. It is the first time a team has stolen that many bases in an inning since the Rangers in 2010. Those are the only such occurrences in the last 15 seasons.
TIGERS MEET ROYALS AGAIN, WHITE SOX LOOK TO STAY HOT
Chris Sale (3-0, 2.35 ERA) takes the mound against the Angels' Garrett Richards (0-2) 3.57 ERA) as the White Sox look to continue their terrific start. Todd Frazier finally got going for the White Sox on Tuesday. They need him to return to form if they are going to win the American League Central.
Detroit's lack of depth in their starting rotation is starting to put a damper on their electric line-up. Jordan Zimmermann (2-0, 0.00 ERA), who still has not allowed an earned run, takes the mound on Wednesday. Ian Kennedy (2-0, 0.66 ERA) takes the mound for Kansas City.
