Connelly Early made a powerful entrance in the MLB on Tuesday, striking out 11 batters over five scoreless innings in his debut with the Boston Red Sox.

The 23-year-old left-hander was promoted from the Triple-A Worcester, the minor league associated with the Red Sox, earlier that day due to pitcher Dustin May being placed on the injured list. Early arrived in Sacramento and spent his afternoon reviewing scouting reports in preparation for the fast-approaching game.

The preparation paid off as Early made one of the best pitching debuts in Red Sox history, striking out 11 batters in Tuesday’s 6-0 win against the Athletics. The performance tied with Don Aase‘s 1997 record for the most strikeouts in a Red Sox debut.

“He was really good,” manager Alex Cora told reporters. “He was prepared, too, which was eye-opening. He did his own homework, went through it with the coaching staff, and executed… He was outstanding.”

Early relied on a diverse mix of curveballs and fastballs, striking out 52% of all batters he faced. His dominance in the field continued in his strong season with the minor league.

He combined a 10-3 record and a 2.60 ERA for the 2025 minor league season. Early struck out 132 batters in just over 100 innings before Tuesday’s needed debut.

The rookie’s poise and confidence impressed his new teammates immediately.

“He let out some emotion after some big strikeouts,” right fielder Rob Refsnyder said after the game. “I can’t really think of a better way to start your career.”

His debut could not have come at a better time for the Red Sox, who face depth issues while navigating a playoff chase. With May on the sidelines until further notice, Early could earn another turn in the rotation.

The rookie left a strong first impression, giving the Red Sox stability in a moment of need and showcasing the pitcher’s capability of handling higher-level competition.
