Crawford made his professional debut in 2017, making a single start with the Class A Short Season Lowell Spinners of the New York–Penn League.^[3] He split time during 2018 with the Class A Greenville Drive and Class A-Advanced Salem Red Sox, making a total of 27 starts and compiling a 7–7 win–loss record with a 3.26 earned run average (ERA).^[3] Crawford returned to Salem in 2019, and was promoted to the Portland Sea Dogs of Double-A.^[3] He pitched in only one game after mid-July, and ultimately underwent Tommy John surgery in October 2019.^[4] He did not pitch professionally during 2020,^[3] due to cancellation of the minor-league season, and had surgery mid-year to remove bone spurs in his elbow.^[4]

Crawford was named to Boston's active roster to start the 2022 season.^[13] He was placed on the restricted list in late April prior to a series in Toronto, as he was apparently not vaccinated against COVID-19 (required to enter Canada); he rejoined the team on April 29 in Baltimore.^[14] On May 14, the Red Sox optioned Crawford to Worcester.^[15] He was recalled in June for a week,^[16][17] and again in early July.^[18] On September 4, Crawford was placed on Boston's injured list with a right shoulder impingement.^[19] Overall with the Red Sox during 2022, Crawford compiled a 3–6 record in 21 games (12 starts) with a 5.47 ERA while striking out 77 batters in 77+1⁄3 innings.^[20]

Crawford began the 2023 season with Boston,^[21] and was optioned to Worcester on April 11 when Garrett Whitlock was activated from the injured list.^[22] He was recalled two days later, when Zack Kelly was placed on the injured list.^[23] On May 5, Crawford was placed in the injured list, due to a left hamstring strain.^[24] On May 6, Crawford was ejected from a game and fined for not leaving the field after the conclusion of the national anthem despite an umpire's warning. Philadelphia Phillies pitcher Matt Strahm was also ejected for taking part in the "anthem standoff" where players compete to leave the field last. The ejection and subsequent fine was largely due to the introduction of the pitch clock, intended to speed up the game and prevent unnecessary delays.^[25][26] Crawford was activated from the injured list on May 19.^[27]

Crawford is the younger brother of Jonathon Crawford, who was selected in the first round of the 2013 MLB draft by the Detroit Tigers.^[28]
