Chacin, who is entering his age-30 season, is the second veteran rotation addition for the Brewers in the last week. The club also agreed to terms on a deal with old friend Yovani Gallardo, giving the team options while Jimmy Nelson misses time recovering from late-season shoulder surgery.
Chacin quietly had a solid season for San Diego, posting a 3.89 ERA and 4.26 FIP in 32 starts after signing with the Padres before the season. San Diego had interest in a reunion with the righty, but he ultimately was able to secure a multi-year pact from a Milwaukee club that will contend in 2018.
Milwaukee may not be done adding starters, as the club is expected to play in the market for big-time pieces like Jake Arrieta and Yu Darvish.
