Red Sox Add Right-Handed Reliever Patrick Halligan to Minor League Roster

The Boston Red Sox have added a new arm to their minor league system, signing 26-year-old right-handed relief pitcher Patrick Halligan to a minor league contract, as reported by Andrew Parker of SoxProspects.com on Tuesday.
Halligan, originally drafted by the Kansas City Royals in the 13th round of the 2021 MLB Draft, has spent the past few years working through various minor league systems. His journey through professional baseball has seen him play for the Royals, Atlanta Braves, and Houston Astros organizations, with his most recent stint being with the Astros’ AA team in Corpus Christi.
Halligan’s Journey Through the Minors: A Steady Climb
After being selected by the Royals in 2021, Halligan spent two seasons in the Kansas City farm system. His 2022 campaign featured an appearance at AAA with the Omaha Storm Chasers, which highlighted his ability to pitch at a higher level of competition. However, Halligan’s next two seasons would be spent with the Atlanta Braves organization, where he moved between AA and AAA teams, gaining valuable experience and refining his skills.
During his time with the Mississippi Braves, Atlanta’s AA affiliate, Halligan showcased his potential by throwing 45.1 innings, allowing just 13 earned runs, and posting a respectable 3.24 ERA. His ability to limit runs earned him further recognition, and his performances continued to catch the attention of scouts and organizations alike.
Halligan’s 2025 Season: Striking Out Batters with Command
In 2025, Halligan continued his development with the Houston Astros, spending the majority of the season pitching for the AA Corpus Christi Hooks. Over 51.2 innings, he allowed 20 earned runs, maintaining a solid 3.48 ERA. His ability to generate strikeouts was a highlight, as he fanned 62 batters, posting a rate of 10.8 strikeouts per nine innings. This performance once again demonstrated his ability to overpower hitters with his mix of pitches.
At 230 pounds, Halligan is not known for throwing blazing fastballs, but rather for his ability to generate strikeouts with a low-to-mid 90s fastball complemented by a slider and splitter. His diverse pitch mix allows him to keep hitters off balance and get swings and misses, which has been a key factor in his success at the minor league level.
The Red Sox’s Commitment to Building Depth in the Bullpen
Halligan’s signing with the Red Sox marks the second relief pitcher Boston has added to their minor league roster this week. The team is clearly focused on strengthening their bullpen depth, and Halligan’s experience in multiple organizations, as well as his solid strikeout numbers, makes him a promising addition to their farm system.
For Halligan, the move to Boston provides a fresh opportunity to continue developing his game, with hopes of eventually making his MLB debut. With his ability to generate strikeouts and his continued improvement over the past few seasons, Halligan could be a key part of the Red Sox’s bullpen depth in the near future.
Looking Ahead: What the Future Holds for Halligan
As he embarks on his journey with the Red Sox, Halligan will aim to build on his progress and earn a spot in the major leagues. His strong strikeout numbers and solid ERA indicate that he has the potential to succeed at higher levels, and with continued development, he could be a valuable contributor to Boston’s pitching staff.
The Red Sox will be watching Halligan closely as he continues to refine his skills in the minors, and with his combination of size, command, and strikeout ability, he could find himself making an impact in Boston’s bullpen in the years to come. For now, he will focus on making his case for a spot on the big league roster, and with the Red Sox’s recent commitment to strengthening their pitching depth, Halligan’s future in Boston looks promising.
