Denver, CO (Sports Network) - Colorado Rockies closer Rafael Betancourt may never pitch in the big leagues again.
Betancourt, a veteran of 11 seasons in the majors, has a torn ulnar collateral ligament in his right arm and will undergo platelet-rich plasma treatment as opposed to Tommy John surgery.
The 38-year-old Betancourt said on the team's website he will not go under the knife if the platelet-rich plasma treatment does not work, thus ending his career.
Betancourt has 16 saves this season with a 4.08 earned-run average but has blown his last two save opportunities. He returned from an appendectomy earlier this month.
Over 635 appearances out of the bullpen for the Indians and Rockies, Betancourt has pitched to a 3.19 ERA and allowed just 1.09 walks/hits per games. He owns 74 saves and 142 holds in his career.
