Rockies designate RHP Rafael Betancourt for assignment

DENVER (AP) Colorado Rockies veteran Rafael Betancourt has been designated for assignment, possibly signaling the end of the right-hander's 11-year major league career.

In a corresponding move, Colorado selected the contract of right-hander Simon Castro from Triple-A Albuquerque. The Rockies also recalled right-hander Jairo Diaz and optioned reliever Justin Miller to the Isotopes.

Betancourt, 40, was 2-4 with one save and a 6.18 ERA in 45 appearances this season. He joined the Rockies in a trade with Cleveland in 2009 and helped the team reach the playoffs that season.

He has been with Colorado since and has 58 saves, fifth in franchise history.

He didn't pitch in 2014 after undergoing Tommy John surgery in September 2013. He signed a minor league contract with Colorado in January and made the team out of spring training.

The Rockies also announced they reinstated reliever Brooks Brown from the 15-day disabled list and optioned him to Albuquerque.
