It’s hard to have a better MLB regular-season debut than Cleveland Guardians rookie Chase DeLauter.

In the Guardians' 6-4 win over the Seattle Mariners Thursday at T-Mobile Park, DeLauter homered twice in his regular-season debut, becoming the sixth player to ever do so. 

The top prospect debuted in an American League Wild Card Series last fall, so Thursday wasn’t DeLauter’s first taste of big league action.

"That’s something I’ll never forget," DeLauter said of his postseason debut last year. "I won’t forget this one either, don’t get me wrong."

In the first inning, the 24-year-old clobbered Mariners starting pitcher Logan Gilbert’s 85-mph slider 358 feet over the right-field wall for his first Major League home run, giving the Guardians a 1-0 lead.

He became the fifth player in Cleveland’s 126-year franchise history to hit a home run in his first career regular-season at-bat. He is the first Guardians player to do so since Jhonkensy Noel June 26, 2024.

DeLauter’s second blast of the game came in the ninth inning, when he crushed Mariners reliever Cooper Criswell’s cutter 422 feet into right-center field, providing a key insurance run as he gave the Guardians a 6-4 lead.

"He’s not from this planet," reliever Erik Sabrowski said of DeLauter, according to The Athletic.
