The left-hander became a free agent when Milwaukee failed to offer a contract by Friday's arbitration deadline, which took him off the 40-man roster.
Capuano missed last season after injuring his pitching elbow in an exhibition game in March. The 30-year-old decided to try rehabilitation, but later had the second elbow-ligament replacement surgery of his career and never returned to play.
Capuano won 18 games in 2005 and made the NL All-Star team in 2006. He started 5-0 in 2007, but lost his last 12 decisions.
He would get a $500,000, one-year contract if added to the major league roster and could make $2,825,000 in performance bonuses: $1.2 million based on innings from 60 to 200 and $1,625,000 based on starts from five to 30.
Capuano had a $3.75 million salary last season.
I think this could be a crucial move for the Crew, seeing as Capuano is currently one of the most experienced starting pitchers the Brewers have. I can see him being a key part of the starting rotation next season.
I'd still like to see Milwaukee go after one or two starters, focusing mainly on Oliver Perez and Jon Garland. Rumors have been spread that veteran John Smoltz is interested in joining the Brewers, as well.
