Rafael Betancourt won't concede to age or surgery. The Rockies' former closer continues on the comeback trail. He will arrive at spring training Sunday for a 10-day stint with the team, throwing for the training staff in his recovery from elbow ligament surgery.

"I want to pitch this season. My goal hasn't changed," Betancourt, 38, told The Post on Tuesday. "I don't want to rush anything or have any setbacks. But everything has been positive so far."

Betancourt is a free agent. He has been throwing from 90 feet without issue, another hurdle cleared in his road back. After his camp stint, Betancourt is expected to join the Rockies for practice in Miami during their season-opening series. Bringing the right-hander back on a minor-league deal remains a possibility, even though he wouldn't be ready to pitch until August.
