Chad Bettis, who left the Rockies in early spring to combat testicular cancer, will return to the team Tuesday in Denver. Colorado manager Bud Black confirmed the right-handed pitcher is on his way back to the club. “Chad Bettis will potentially be rejoining the team in a couple days,” Black said Friday at Petco Park before the Rockies started a three-game series against the Padres. “I’ll make it official when it becomes official. I’ll let you know.” Bettis on March 10 decamped from spring training after doctors discovered cancer had spread. Bettis thought he was in the clear. He had returned to the team in February after surgery to remove the cancer in December. Bettis underwent months of chemotherapy, finishing May 16. Then he waited for a cancer marker blood test to determine if the treatment was successful. It was.
