Bettis was set to start Monday night at Coors Field in his first major league game since being diagnosed with testicular cancer in November. After undergoing surgery and chemotherapy, he was ready to pitch against the Atlanta Braves.
"It's really cool with all the stuff he's been through he's back here and ready to go," Rockies teammate Jon Gray said. "I can't wait to see him compete."
The 28-year-old Bettis discovered a lump on his testicle last fall and underwent surgery to remove the testicle. He passed subsequent follow-up screenings and was healthy enough to report to spring training. But a regular screening on March 10 led to a biopsy being performed, which revealed the cancer had spread to his lymph nodes.
Bettis underwent nine weeks of chemotherapy but kept up his conditioning throughout. He was sent on a minor league rehab assignment July 13 and worked his way back to the rotation, much to the pleasure of his team.
"Everyone loves him," Colorado third baseman Nolan Arenado said. "He tries to help. I always see him in the video room trying to help the young guys. He's just a great teammate."
Bettis' return is expected to be emotional, but the Rockies are hoping he can boost the staff. He led Colorado in starts (32), wins (14) and innings (186) last season. His best outing was a two-hit shutout against the San Francisco Giants on Sept. 5. He was expected to anchor a young rotation this season before being diagnosed with cancer.
He comes back to a team holding onto the second National League wild-card spot. Colorado was 21 games above .500 in June but has gone 18-26 since, so getting Bettis back gives the Rockies a chance to strengthen the rotation.
"This is a pitcher, when he's throwing well, will have an impact on the game every time he takes the mound," Rockies manager Bud Black said. "He wants to be a part of this and make a contribution."
