The Chicago White Sox and Boston Red Sox paired up for a trade for the second time in a little more than a week. The White Sox acquired left-handed reliever Cam Booser from the Red Sox on Saturday afternoon for minor-league right-hander Yhoiker Fajardo. Booser, 32, went 2-3 with a 3.38 ERA, one save and 43 strikeouts in 43 relief appearances for the Red Sox in 2024, his first season in the majors. He spent 2013-17 in the Minnesota Twins minor-league system and, after some time as a carpenter, according to The Associated Press, played independent baseball in 2021 with the Chicago Dogs. His 2022 included time in the Arizona Diamondback farm system and independent baseball in Lancaster, Pa. He joined the Red Sox organization in 2023, appearing in 48 games at Triple-A Worcester. He made his major-league debut on April 19, 2024, against the Pittsburgh Pirates. At 31 years, 351 days, Booser became the oldest Red Sox player to debut since Tommy Fine in 1947 (excluding those who had previously competed in Japan). Booser in September was recognized as the Lou Gorman Award winner, given annually to a Red Sox minor-league player who has demonstrated dedication and perseverance in overcoming obstacles while working his way to the major-league team. Fajardo went 1-4 with a 3.91 ERA and 64 strikeouts in 13 starts with the Dominican Summer League White Sox last season. The White Sox originally signed Fajardo, 18, as an international free agent on Feb. 20, 2024. The White Sox made a major trade with the Red Sox earlier this month, sending left-hander Garrett Crochet to Boston on Dec.11 for four minor-league prospects: in catcher Kyle Teel, outfielder Braden Montgomery, infielder Chase Meidroth and right-handed pitcher Wikelman Gonzalez. To make room for Booser on the 40-man roster, the White Sox designated outfielder Corey Julks for assignment. Julks, 28, had a  .214 average with seven doubles, three home runs and 14 RBIs in 66 games after being acquired in a trade with the Houston Astros on May 15. With Saturday’s moves, the White Sox 40-man roster remains at 40.
