Kelly also allowed his 1st HR to a RHH on 8/18 vs. NYY and allowed none to his first 100 RHH faced. His 1.19 ERA on the road ranked him 4th in the majors and 2nd in the AL behind only Andrew Miller. In 28 games against opponents outside of the AL East, he posted a 1.30 ERA and a .173 opponent AVG. He posted a career-best 22.0-inning scoreless streak from May 1-July 9, the longest of the season for any AL reliever and any Red Sox pitcher. Throughout his 22.0-inning scoreless streak, he posted a .184 opponent AVG and a 0.98 WHIP.

Some of Kelly´s abilities are throwing a fastball that can reach up to 102.2 miles per hour and complementing it with a sinking fastball and slider. His sinker shows dramatic horizontal movement, while paradoxically, not showing the kind of vertical movement of other sinkerballers such as former teammate Justin Masterson and is one of the fastest in the game, at about 93 miles per hour. He also throws a changeup to left-handed batters and an infrequent curveball.
On March 14, 2022, Kelly signed a two-year, $17 million contract with a club option for the 2024 season with the Chicago White Sox.
Joey Kelly was traded to the Los Angeles Dodgers on July 28, 2023.
