DENVER -- Righty reliever Rafael Betancourt's comeback from Tommy John surgery last September had reached a new level.
Betancourt, 39, who was with the Rockies 2009-13 with most of that time as the closer, signed a Minor League deal this summer. He made 14 appearances at Rookie Ball Grand Junction (1-0, 2.03 ERA), before making scoreless appearances for Colorado Springs Sunday and Monday against Fresno.
Betancourt ranks fifth in Rockies history with 57 saves, and is tied with Mike DeJean for eighth in club history in pitching appearances with 264.
"He's building himself up," Rockies manager Walt Weiss said. "Obviously, missing as much time as Raffy has, he needs to go out and pitch. He's healthy now. He's pitching again. You know how much we love Raffy as a teammate, and we'll see if there's an opportunity here to get him in the mix down the stretch."
