The Chicago White Sox are moving on from Dylan Cease. The team traded Cease to the San Diego Padres on Wednesday, Yahoo Sports’ Russell Dorsey confirmed.

Going back to the White Sox will be pitching prospects Drew Thorpe and Jairo Iriarte, outfield prospect Samuel Zavala and reliever Steven Wilson, the team later announced. MLB Pipeline ranks Thorpe as the No. 5 prospect in San Diego’s system, Zavala at No. 7 and Iriarte at No. 8. Thorpe is also ranked as the No. 85 prospect in baseball. Wilson holds a 3.48 ERA in 106 career innings across two seasons for the Padres.

Becoming a Padre has at least one very immediate impact for Cease: The team was scheduled to fly to South Korea on Wednesday for its two season-opening games against the Los Angeles Dodgers next week. Yu Darvish and Joe Musgrove were already named the probable starters for those games.

The move signals more change for the White Sox, who fired former general manager Rick Hahn and vice president Kenny Williams in August. Chris Getz, who played for the White Sox for two years before joining the team’s front office after he retired, was promoted to replace Hahn in late August.

The move marks the biggest trade — and arguably the biggest decision — Getz has made since taking over the reins. He also declined an option on shortstop Tim Anderson in November and acquired five players from the Atlanta Braves for reliever Aaron Bummer later that month. But dealing Cease is a whole other level of transaction.
