Madison Bumgarner was ejected in bizarre circumstances as the Arizona Diamondbacks defeated the Miami Marlins 8-7 on Wednesday.

Giving up a lead-off home run to Jon Berti in the first inning, Bumgarner retired the next three batters before he was called for a foreign substance check by first-base umpire Dan Bellino.

The notoriously fiery Bumgarner responded angrily to a prolonged check, with Bellino staring at him, and was consequently ejected for swearing at the umpire.

Daulton Varsho homered for the D-Backs, who claimed a three-game series sweep against the Marlins with the win.

After a sluggish start to the season, Arizona have claimed seven wins in their past nine games – including victories over the Los Angeles Dodgers and the St. Louis Cardinals – to get back to .500.

Dodgers dominate in NL West battle

The Dodgers claimed their second win of a two-game home series against the San Francisco Giants, earning a comfortable 9-1 victory.

Mookie Betts and Max Muncy homered and Freddie Freeman hit a two-run triple as the Dodgers broke the game open late, scoring six runs in their final two at-bats.

With the Giants dropping these two games, they now sit two and a half games behind the Dodgers, who top the NL West.

Blue Jays break Yankees streak

In another big division matchup on Wednesday, the Toronto Blue Jays ended the New York Yankees' 11-game win streak with a 2-1 victory.

Matt Chapman homered in the second inning for Toronto against their AL East rivals, before Vladimir Guerrero scored the winning RBI single in the third. 

Blue Jays starter Yusei Kikuchi pitched solidly, striking out seven and giving up only three hits over 78 pitches in a season-high six innings.

Fernando Tatis Jr. put on a show as the San Diego Padres scored seven unanswered runs to rally past World Series champions the Los Angeles Dodgers 8-7 after 11 innings in another thrilling MLB showdown.

The Padres trailed National League (NL) West rivals the Dodgers 7-1 at the end of six innings, but Tatis fuelled the visitors to an epic extra-innings victory in Los Angeles on Sunday.

Tatis scored the game-winning run on Eric Hosmer's sacrifice fly in the 11th inning as the Padres became the first team since the 1918 San Francisco Giants to win a game, despite being on the road, facing a side with a .700 per cent winning percentage, trailing by six-plus runs in the seventh inning or later, per Stats Perform.

San Diego's Tatis hit another home run after back-to-back multi-homer games against the Dodgers, making it five home runs in three appearances as the NL West blockbuster continues to provide postseason energy in April.

According to Stats Perform, Tatis became the first player in MLB history to have five-plus home runs and two-stolen bases in a road series.

Tatis has two games with at least one home runs and two stolen bases – Tony Gwynn is the only other player in Padres history to achieve the feat, while he is the eighth shortstop with at least one three-game span of five-plus homers.

Dustin May had a career-high 10 strikeouts for the Dodgers. Aged 23 years and 231 days, he is the youngest pitcher in franchise history with 10-plus strikeouts in a game since Clayton Kershaw (23 years and 169 days) in 2011.

Bumgarner dominates with unofficial no-hitter

Madison Bumgarner threw a seven-inning no-hitter to guide the Arizona Diamondbacks to a 7-0 shutout of the Atlanta Braves, clinching a sweep of the doubleheader. Bumgarner struck out seven batters, but it will not officially count as MLB rules stipulate such a game must be a contest of nine or more innings that ended with no hits. The Diamondbacks, meanwhile, became the first team to allow one or fewer hits in a doubleheader after Zac Gallen held the Braves to one hit in the 5-0 opener.

Trevor Story hit a grand slam – the third of his career – in a seven-run fourth inning as the Colorado Rockies routed the Philadelphia Phillies 12-2.

The Cleveland Indians defeated the struggling New York Yankees 7-3 behind Franmil Reyes' three-run homer, triple and first stolen base.

A's crash back down to earth

The Oakland Athletics and their 13-game winning streak was snapped by the Baltimore Orioles, who were 8-1 victors. It was Oakland's third longest winning streak since 1968.

Patrick Corbin was put to the sword in the Washington Nationals' 4-0 loss to the New York Mets. Corbin, who suffered his 10th consecutive decision, allowed four runs, seven hits and three walks in four-plus innings.

Oh-tani!

The Los Angeles Angels avoided a sweep against the Houston Astros thanks to some help from Shohei Ohtani. The two-way star crunched a 440-foot homer in the eighth inning to give the Angels a 3-2 lead. The Angels beat the Astros 4-2.
