Rookie Devin Williams of the Milwaukee Brewers has been voted the National League Reliever of the Month Presented by The Hartford for September, and Mike Mayers of the Los Angeles Angels has been voted the American League Reliever of the Month Presented by The Hartford for September. The announcements were made earlier today on MLB Network.

Williams earned his first career monthly award and is the first Brewers winner since his bullpen-mate Brent Suter in September 2019. The Brewers have collected a league-best six Reliever of the Month Awards since 2018, also received by Josh Hader (April-June 2018), Corey Knebel (September 2018) and the aforementioned Suter. Mayers also claimed his first career Reliever of the Month Award and became just the second Angels pitcher to accomplish the feat, joining Francisco Rodríguez, who won a pair in August 2006 and June 2008.

• Logged a perfect 1-0 record over nine appearances for the Brewers. Tallied 24 strikeouts while permitting just three walks and four hits across 13.0 scoreless innings pitched.

• Allowed his only earned run of the season on July 27th against the Pittsburgh Pirates. Since that game, tossed 24.2 consecutive innings over 20 appearances without allowing an earned run.
