The Tampa Bay Rays claimed a franchise record and moved a step closer to an MLB record with Wednesday's 9-7 win over the Boston Red Sox that extended their season-opening streak to 12 wins.

The Rays improved to 12-0 with the win that included only one home run this time, coming from Randy Arozarena's first-inning opposite field three-run blast.

Taj Bradley fanned eight batters across five innings on his majors debut, allowing five hits, one walk and three runs, before Rafael Devers tightened up the scoreline with a three-run homer in the seventh inning.

But Arozarena's eighth-inning sacrifice fly meant Tampa Bay had done enough to extend their winning streak, meaning they are one short of matching the 13-0 starts by the Milwaukee Brewers (1987) and the Atlanta Braves (1982) which are the longest ever in MLB history.

The Rays matched a franchise record for a winning streak, previously 12 in a row from June 2004.

Tampa Bay have outscored their opponents 92-27 through the first dozen games, blasting 30 homers, which is only bettered by the 2019 Seattle Mariners (32) and the 2000 St Louis Cardinals (31).

Arozarena was struck out twice had four RBIs while Wander Franco went three-for-five with two RBIs and two runs.

Franco's fourth-inning two-run double opened up a 6-1 lead but the Red Sox did well to rally after reliever Zack Kelly left in the fifth with right elbow pain, while Devers snapped a run of 10 hitless at-bats.

The Rays can match the MLB record 13-0 season-opening start when they face the Red Sox again on Thursday.

Yankees win after Boone tossed & ump hospitalised

Aaron Boone was ejected early and Franchy Cordero homered for the fourth time this season as the New York Yankees rallied from a three-run deficit to beat the Cleveland Guardians 4-3.

Yankees manager Boone was tossed in the first inning following a confusing play, while second base umpire Larry Vanover was taken to hospital during the fifth after being struck in the face by a relay throw.

Vanover was struck in a bizarre sequence from Kyle Higashiakoa's RBI single, with the incident allowing Isiah Kiner-Falefa to score after Oswaldo Cabrera had plated.

Cordero tied the game with a 439-feet seventh-inning blast, before Cabrera's ninth-inning go-ahead single. Closer Clay Holmes was nervy, loading the bases on a hit batter, but finished the job.

Bregman finds form as Astros triumph

Alex Bregman homered for the second straight game as the inconsistent Houston Astros thrashed the Pittsburgh Pirates 7-0.

Bregman's three-run blast in the seventh inning opened up a 5-0 lead, after rookie outfielder Corey Julks crushed his maiden homer into left field in the fourth inning.

The Astros rode the pitching of Jose Urquidy who allowed only two hits – both singles - and three walks across six scoreless innings, striking out two.

The Tampa Bay Rays extended their season-opening winning streak to 11 games with Brandon Lowe homering for the fourth straight game in a 7-2 triumph over the Boston Red Sox on Tuesday.

The relentless Rays moved closer to history with the win where starter Shane McClanahan put in a strong display fanning nine batters across five innings allowing two hits and one run.

Tampa Bay are within reach of matching the best-ever MLB start since 1900, which is 13 wins held by the 1987 Milwaukee Brewers and the 1982 Atlanta Braves.

The Rays continued their dominant ways, after Monday's 1-0 win over the Red Sox, with an 83-20 run differential across those 11 games.

Brandon Lowe, Yandy Diaz, Isaac Paredes and Josh Lowe all homered for the Rays, who were 5-0 up after five innings.

Diaz and Brandon Lowe hit back-to-back solo homers with two out in the fifth inning to open up the 5-0 lead.

Tampa Bay have 29 homers across 11 games, which is a joint majors record through 11 games alongside the 2000 St Louis Cardinals.

Mountcastle rips franchise record in O's rally

Ryan Mountcastle hit a grand slam and a three-run homer to tie a franchise record nine RBIs to fire the Baltimore Orioles to a 12-8 win over the Oakland Athletics.

The A's led 7-3 in the fifth inning before Mountcastle led the rally with a three-run blast at the bottom of the same inning to bring it back to a one-run game.

Mountcastle produced his grand slam in the seventh with a 456-foot homer to left field, after Austin Hays, who had four hits, singled to drive in Gunnar Henderson.

The O's first baseman went three-for-four with two runs and nine RBIs, while Grayson Rodriguez sent down six strikeouts but allowed six hits, four walks and five runs in his home debut.

Cordero and Cole star in Yankees triumph

Franchy Cordero blasted a three-run homer and Gerrit Cole rallied after the Cleveland Guardians' fast start as the New York Yankees prevailed 11-2 to improve their record to 7-4.

Cole gave up two runs and three hits in the first inning but responded with six scoreless innings, finishing with three strikeouts, allowing only five hits.

Cordero's 368-feet blast opened up a 6-2 lead as the Yankees piled on five runs in the third inning, with Anthony Rizzo going two-for-three for two RBIs while Aaron Judge went two-for-five with one run.
