The Milwaukee Brewers are set for a potential overhaul in their starting rotation as right-handers Frankie Montas and Colin Rea head into free agency. Montas declined a mutual option worth $20 million, while the Brewers opted against Rea's $5.5 million club option, resulting in buyouts for both players.

This season, Montas recorded a 7-11 record with a 4.84 ERA, while Rea had a 12-6 record and a 4.28 ERA. Other notable roster moves include the New York Mets claiming Kevin Herget off waivers and the Chicago Cubs claiming Rob Zastryzny.
