What happened: The Cubs acquired veteran right-hander Aaron Civale from the Athletics after Oakland designated him for assignment. The Athletics receive Class S pitcher Aiden Moffett in return.

Why it matters: This marks a second stint in Chicago for Civale, giving the Cubs added pitching depth as they navigate the stretch before the trade deadline. Moffett gives Oakland a lower-level arm to develop in return for a pitcher it had already cut loose.

What to watch: Watch for Civale's role assignment — rotation or bullpen — once he reports to Chicago.
