The Seattle Mariners outgunned the San Diego Padres in a slog-fest as the former triumphed 16-13.
A five-run sixth inning was followed by a nine-run effort as the Mariners finally got their bats out after the Padres set the pace early with a four-run first inning.
But the Mariners were clinical when they got on base and finished with 16 runs from 16 hits as they did the majority of their damage in the seventh, with Kyle Seager, Dae-ho Lee, Chris Iannetta, Stefen Romero, Shawn O'Malley, Norichika Aoki and Franklin Gutierrez all picking up RBI singles.
Meanwhile, the San Francisco Giants shut-out the Atlanta Braves in a 6-0 win as Madison Bumgarner fanned 11 Braves and even scored a homer in the big win.
The knock gave the Giants ace the 13th home run of his career - the most of any active pitcher - on a day to remember for the 26-year-old.
The Baltimore Orioles and the Boston Red Sox put on a show of their own as former triumphed 12-7.
Baltimore failed to record a single homer in the opening three games of the season, but they teed off seven times in the fourth as Mark Trumbo and Adam Jones registered two each, while David Ortiz went deep for the Red Sox with a three-run effort in the sixth.
The Minnesota Twins won a see-saw match against the Tampa Bay Rays 6-4 as Brad Miller hit home twice off the back of two Evan Longoria efforts - the first an RBI single at the top of the third and a homer at the top of the fifth.
The New York Yankees have improved to 25-28 to match Detroit Tigers' tally for the season after beating them 5-4, as the Cleveland Indians toppled the Kansas City Royals 5-4 and the Milwaukee Brewers knocked off the Philadelphia Phillies 4-1.
The Chicago Cubs beat the Los Angeles Dodgers 7-2, the Arizona Diamondbacks shut-out the Houston Astros 3-0, the Pittsburgh Pirates lost 4-3 to the Miami Marlins after 12 innings and the Cincinnati Reds trumped the Colorado Rockies 11-4.
BUMGARNER EXTENDS GOLDEN RUN
Giants ace Bumgarner continued his sparkling season by tossing 7 2/3 scoreless innings in a 6-0 win against the Atlanta Braves. Bumgarner struck out 11 batters and gave up just four hits as he improved to 7-2 with a 1.91 ERA. To top it off, he even managed a homer.
NUNEZ KEEPS IT IN THE PARK
Twins shortstop Eduardo Nunez cruises to an inside-the-park home run after a misfield deep in the outfield.
CUBS KEEP IT TIGHT
Over their last six games, the Chicago Cubs starters have a 0.89 ERA. On Thursday, Kyle Hendricks outduelled Julio Urias by giving up just two runs in eight innings, improving to 4-4 for the season.
Meanwhile, Brewers shortstop Jonathan Villar, who hit a home run Thursday, leads MLB with 19 stolen bases. The last shortstop to lead the majors in stolen bases was Jose Reyes with 78 in 2007.
SYNDEGAARD HUNTING MARLINS
Noah Syndergaard (5-2, 1.84 ERA) has been terrific this season. The flamethrower has been used out of the bullpen in addition to mowing down batters as a starter. He will face off against Tom Koehler (3-5, 4.50 ERA) and the sneaky-good Marlins.
