Biographical Information

Pitcher Hayden Mullins was drafted by the Boston Red Sox in the 12th round of the 2022 amateur draft out of Auburn University. He was part of the Tigers team that played in the 2022 College World Series. He began his professional career in 2023 but made only 4 starts that year and had to wait until 2024 to record his first professional win, which came with the Greenville Drive of the South Atlantic League. In 22 games including 17 starts that year, he went 4-5, 3.94, logging 89 innings.

He emerged as a significant prospect in 2025 when he combined to go 8-2, 2.21 between Greenville and the Portland Sea Dogs of the AA Eastern League. He made 21 starts in 22 appearances, pitched 101 2/3 innings, allowed just 62 hits, struck out 123 batters and walked 51. He was back at Portland for the start of the 2026 season and in his first appearance on April 7th, he was at the center of a historic inning. Facing the New Hampshire Fisher Cats, he struck out the side in the top of the 1st, but then things went awry in the 2nd, after he issued a lead-off walk. That batter scored on a sacrifice fly, but it was the second out of the inning and he had still not issued a hit, but he proceeded to walk the next three batters, forcing in another run, and was replaced by Jorge Juan. That's when things turned truly bizarre as Juan was unable to record the third out, instead issuing three more walks, plunking two batters, and throwing two wild pitches for good measure. A third reliever, Cade Feeney had to complete the inning, and after yet another wild pitch, he gave up the first hit of the frame, a two-run single to Ismael Munguia, before finally recording the third out. New Hampshire had scored ten runs on just one hit, while Hayden's line was 1 2/3 innings pitched with 0 hits and 4 Ks, but also 5 runs allowed on 5 walks.
