BOSTON -- The Royals released veteran right-hander Clay Buchholz on Tuesday, the day of his opt-out clause in his Minor League deal.
Buchholz, 33, had been signed on March 25. He threw 16 Minor League innings between Double-A Northwest Arkansas and Triple-A Omaha, giving up 10 hits and two runs, along with seven walks and nine strikeouts.
Buchholz, a former All-Star with the Red Sox, was traded to the Phillies prior to the 2017 season. He then missed most of the year because of right forearm surgery.
