The Chicago Cubs claimed starting pitcher Aaron Civale off waivers on Sunday after the Chicago White Sox designated him for assignment, setting up a cross-city move.

Civale’s stint with the White Sox lasted just 2 1/2 months after he was traded, along with cash considerations, from Milwaukee for Andrew Vaughn on June 13. Over his time with the White Sox, Civale made 13 starts and had a 2-7 record with a 5.37 ERA, 55 strikeouts and 26 walks over 67 innings.

While he has a career-worst 5.26 ERA so far this season, the Cubs are hopeful the 30-year-old right-handed pitcher can boost their rotation for their stretch run. Chicago entered the day 6 1/2 games back of Milwaukee in the National League Central, but leads the NL wild-card standings with a 9 1/2-game lead over the first team out of the playoffs, the Cincinnati Reds.

Over his six-year major league career, Civale has a 42-44 record and a 4.18 ERA over stops in Cleveland (2019-23), Tampa Bay (2023-24), Milwaukee (2024-25) and with the White Sox.

To make room for Civale, the Cubs designated left-handed pitcher Tom Cosgrove for assignment. He made just two relief appearances for the Cubs, allowing one run on three hits over four innings. He has a career 3.86 ERA over 70 innings across three major league seasons.

The White Sox selected the contract of right-handed pitcher Bryse Wilson to replace Civale after he was claimed. Wilson, 27, started the season on the team’s major league roster, but was designated for assignment on June 10 with a 6.95 ERA over 19 games (five starts).

Wilson, who has a career 4.84 ERA over 459 major league innings, is 4-2 with a 3.86 ERA, 36 strikeouts and eight walks in 14 games (seven starts) for Triple-A Charlotte this season.
