Veteran left-hander Dallas Keuchel elected to become a free agent Wednesday, the Milwaukee Journal-Sentinel reported, after he was designated for assignment by the Milwaukee Brewers on Sunday and cleared waivers.
Milwaukee acquired Keuchel, 36, in a deal with the Seattle Mariners on June 25 and added to the starting rotation after a number of injuries to the starting staff.
In four starts with the Brewers this season, Keuchel had a 5.40 ERA in 16 2/3 innings without a decision. In 13 major league seasons, the 2015 American League Cy Young Award winner with the Houston Astros is 103-92 with a 4.04 ERA in 282 appearances (267 starts).
After pitching his first seven seasons with the Astros, Keuchel has made appearances for six different teams in the past six seasons.
