Chacín finalizes minor league deal with Twins
He would get a $1.6 million, one-year contract if added to the 40-man roster and would have the chance to earn $1.5 million in performance bonuses based on innings.
The 32-year-old right-hander was 15-8 with a 3.50 ERA for Milwaukee in 2018 after signing a two-year, $15.5 million deal with the Brewers.
He beat St. Louis on opening day last year and won at Cincinnati in his second start, then went 1-10 with a 6.00 ERA in his next 17 starts. After his release, he signed with the Boston Red Sox and was 0-2 with a 7.36 ERA in five starts and one relief appearance.
Michael Pineda will miss the first 36 games while completing a suspension for a positive test for a banned diuretic, and Rich Hill is not expected back until June following elbow surgery.
