MLB roundup: Corbin Burnes guides O's to crushing victory over Angels in season opener

In his Baltimore debut, Corbin Burnes threw six innings of one-hit baseball as the Orioles defeated the Los Angeles Angels 11-3 in their opener on Thursday.

Cedric Mullins hit a three-run homer and Anthony Santander contributed a two-run shot, accumulating four RBIs for the American League East champions.

Burnes (1-0), who was acquired from the Brewers in February, struck out 11 batters and did not issue any walks, with Mike Trout's first-inning homer being the only hit against him.

Angels' starter Patrick Sandoval (0-1) gave up five runs, three of which were earned, in 1 2/3 innings, as they began the post-Shohei Ohtani era with a challenging game. Sandoval allowed six hits, walked two, and struck out two.

In the season opener between the Diamondbacks and Rockies, Lourdes Gurriel Jr. had an outstanding performance, hitting a two-run homer in the first inning and driving in three runs in the record-breaking 14-run third inning.

Arizona dominated the game with an 18-hit attack and set a modern major league record for the highest-scoring inning on Opening Day.

Ketel Marte and Gabriel Moreno also contributed to the Diamondbacks' victory with multiple hits and runs. On the pitching side,

Zac Gallen allowed only one run and three hits over five innings. The final score was Diamondbacks 16, Rockies 1.

The Texas Rangers secured a 4-3 victory over the Chicago Cubs in a thrilling season opener. Jonah Heim, who had made a mental mistake earlier in the game, redeemed himself by delivering a walk-off single in the 10th inning.

The Cubs took a controversial lead in the ninth inning when Michael Busch scored on a wild pitch, but replays showed that Miles Mastrobuoni made contact with the pitch.

Texas' Travis Jankowski and Adolis Garcia contributed with a pinch-hit homer and a solo shot, respectively. Cubs' ace Justin Steele left the game due to a left hamstring injury.

In the matchup between the Red Sox and Mariners, Tyler O'Neill made history by hitting a home run on Opening Day for the fifth consecutive season.

His impressive feat helped lead the Red Sox to a 6-4 victory over the Mariners in Seattle.

O'Neill, a former Mariners draft pick acquired from St. Louis, broke the record of four set by Yogi Berra, Gary Carter, and Todd Hundley.

Right-hander Brayan Bello pitched five solid innings for the Red Sox, allowing two runs on five hits with no walks and two strikeouts, with Kenley Jansen pitching the ninth for the save.

Boston's Rafael Devers went 2-for-5 with a double and a two-run homer. Mitch Haniger and Dylan Moore hit two-run shots for the Mariners, who had won their previous three openers and 14 of 17.

In the Dodgers vs. Cardinals game, Mookie Betts and Freddie Freeman hit home runs, while Shohei Ohtani and Tyler Glasnow made key contributions in their first home game for Los Angeles.

Ohtani reached base in his first three trips to the plate with a pair of hits and a walk, receiving a standing ovation from the crowd before his first at-bat.

Paul Goldschmidt hit a home run for the Cardinals, but their injury woes were too difficult to overcome.
