Boston Red Sox Top Prospect Throws Incredibly Rare Immaculate Inning

Mullins, 24, is ranked as the No. 30 prospect in the organization, per MLB.com. He was a 12th-round pick of the Red Sox in 2022 out of Auburn. He's projected to make his major league debut in 2026.

The following comes from a portion of his MLB.com prospect profile:

Mullins' fastball operates in the low 90s and tops out at 95 mph, yet it misses plenty of bats because it features tremendous carry up in the strike zone. He'll flash a plus low-80s slider with two-plane depth at times and can turn it into a harder, tighter cutter that's similarly effective. His low-80s changeup lacks the consistency of his other offerings but has quality tumble at its best and helps him keep right-handers in check.

It's unclear what plans the Red Sox have for Mullins, but it does look like there will be opportunity in 2026. Lucas Giolito is scheduled to be a free agent after this season, as is Walker Buehler.

Giolito has pitched better of late, but Buehler has struggled mightily this season, pitching to a 5-6 record and a 6.45 ERA. The Red Sox entered play on Tuesday at 42-44 and in fourth place in the American League East. They haven't made the playoffs since the 2021 season, when they went to the ALCS.
