What happened: The Chicago Cubs acquired right-hander Aaron Civale and cash from the Athletics in exchange for right-hander Aiden Moffett, according to MLB. Civale returns to Chicago after a run in the Athletics rotation that began after his June activation.

Why it matters: The move adds pitching depth for Chicago 17 days before the Aug. 3 trade deadline, a stretch in which the club has already lost reliever Aaron Bummer to free agency and fielded speculation around Matt Shaw and Luis García Jr. Civale gives the Cubs another established arm to lean on as they navigate a thin bullpen and a one-game losing streak.

What to watch: Watch for Civale's spot in the Cubs' rotation and further bullpen moves as Chicago approaches the Aug. 3 deadline.
