CHICAGO — The Chicago White Sox have acquired right-handed pitchers Ray Castro and Joseph Jarneski from the Texas Rangers in exchange for right-hander Nate Jones, international signing bonus pool money and cash considerations.
Jarneski, 19, has appeared in 10 games with the Arizona Rookie League Rangers this season, going 2–0 with a 1.62 ERA (3 ER/16.2 IP) and 16 strikeouts. The 6-foot, 170-pound Jarneski missed the entire 2018 season while recovering from right elbow surgery in September 2017. A native of Keaau, Hawaii, Jarneski made eight appearances in 2017 after being selected in the 12th round of the 2017 First-Year Player Draft out of Hilo (Hawai’i) High School.
