The season is about to close on the Rockies’ newest closer. Adam Ottavino revealed Monday he probably will have season-ending Tommy John surgery to repair an injured right elbow.

Ottavino was put on the disabled list last week with what the team called right triceps inflammation. But after consulting with team doctor Thomas Noonan, Ottavino learned he has a partial tear of the ulnar collateral ligament in his right elbow.

“It was devastating news, but I want to be a part of this team this year,” Ottavino said in the clubhouse before the Rockies’ scheduled game against the Arizona Diamondbacks.

Ottavino will meet with Dr. James Andrews, a surgeon who has worked with several major-league players who faced Tommy John surgery, including the New York Mets’ Matt Harvey. Ottavino will use his meeting with Andrews as a second opinion to confirm that the surgery is necessary.

“If he agrees, then I’ll just get the surgery right then and there,” Ottavino said.

For now, Ottavino has resigned himself to being out for at least a year.

“Baseball is my love,” he said, “so I will do everything I can to come back. I’ve accepted it. I’ll take it head on.”

Ottavino ascended into Colorado’s closer role this season while pitching in the best form of his career. He’ll finish the season with a 0.00 ERA, having pitched 10 innings without allowing a run. He had 13 strikeouts and two walks. He had three saves.

“It just goes to show how weird this game is,” shortstop Troy Tulowitzki said. “You can be on top of your game like Adam was. He was really becoming a force, somebody we wanted to see in the game. And then something happens.”

Ottavino started throwing with higher velocity in the second half of last season. His fastball this season averaged 95.4 mph, up from 91.5 in 2013, according to MLB pitch data. He also added two sliders to his repertoire, giving him three put-away pitches. It turned him into a multipurpose late-inning stopper.

The Los Angeles Dodgers’ Brandon McCarthy, who suffered a season-ending elbow ligament tear last week, also increased his velocity suddenly this season. His fastball was averaging 93.4 mph this year, up from a career average of 89.8.

“If it’s going to happen, at least I have a good shot at pitching sometime next year and coming back strong,” Ottavino said. “This is something a lot of people have to deal with. I’m not alone in this way.”

The Rockies’ bullpen, already overtaxed by having thrown the most innings among National League relief crews, will now be without another arm.

LaTroy Hawkins, who began the season as the team’s closer, is on the disabled list with a biceps strain. Ottavino was his replacement.

John Axford took over Colorado’s closer’s role in place of Ottavino. Rafael Betancourt will fill in for Axford when necessary.

The Rockies have several pitchers who have undergone Tommy John surgery, including Jorge De La Rosa, Tyler Chatwood and Betancourt.

De La Rosa was out for more than a year, and Betancourt returned this season at the age of 39 after his 2013 season was ended early with a torn elbow ligament. Chatwood is still recovering after undergoing surgery last July.

“It’s certainly a tough day,” manager Walt Weiss said. “These are the cards we’ve been dealt and Adam has been dealt. It’s not fair. You wish it were different. Now you get a plan of attack in place and get after it.”
