An art collection hangs on the wall of the KOA radio booth at Coors Field, vibrant oil paintings portraying a who’s who of Rockies icons.

Here is Todd Helton, arms stretched overhead as he realizes he’s going to the 2007 World Series. And there is Nolan Arenado, his face bloodied, his jersey covered with infield dirt, as he emits a primal scream after hitting a walk-off home run to complete the cycle on Father’s Day 2017.

“Tulo” is captured, too, as are “CarGo,” “Chuck Nazty” and Matt Holliday’s famous crash-landing slide into home plate to win Game 163 against the Padres during Rocktober.

There is also a quiet, subtle portrait of the late Keli McGregor, the team president who died unexpectedly in 2010 at age 47.

The artist in residence is Jack Corrigan, now in his 21st season calling Rockies games and his 38th in Major League Baseball.

“I have known and worked with Jack for 14 years, but I didn’t know until recently that he had this incredible artistic talent,” said Jerry Schemmel, Corrigan’s KOA broadcasting partner. “And it’s really cool to have some of that talent displayed in our radio booth.”

Corrigan, 70, has been a sports fanatic since he was a kid growing up in his beloved Cleveland. He played wide receiver at Cornell University and is now a volunteer assistant football coach at Regis Jesuit High School. He’s done TV broadcasts for the Cleveland Cavaliers, 17 years calling Guardians games, and scores of college football and basketball games.

Sports have enriched Corrigan’s life immeasurably — he’s called more than 3,000 Rockies games — but sports have never defined him. His parents, John and Eileen, made sure of that.

“My parents were always about, ‘Be more than just the job that you have,’ ” Corrigan said. “I’ve always thought that was wonderful advice.”

And he took it to heart. Corrigan has written two novels, “Warning Track,” the tale of a declining baseball player dealing with the temptation and pitfalls of PEDs, and “Night of Destiny: 24 December 1,”  a fictionalized account of a largely unknown incident near the end of World War II that involved his late father.

Corrigan, along with his six siblings, was a member of the drama club at St. Ignatius High School. For a time, he considered majoring in theater at Cornell before switching to history.

“I just couldn’t do both theater and football, too much crossover of schedules,” Corrigan recalled. “Football just took too much time.”

But Corrigan was part of a production of Shakespeare’s “The Winter’s Tale,” which starred a 6-foot-4, 165-pound beanpole named Christopher Reeve as King Polixenes. Reeves, of course, would later gain stardom playing Superman on the big screen.

“Christopher was in the front of the stage, acting, while I was in the back of the house helping run the lighting,” Corrigan recalled with a laugh. “I think that’s where I belonged.”

Corrigan fell in love with painting when he was 6 years old after he received a paint-by-numbers set for his birthday. Painting remained his hobby well into college when he painted a 7-by-12-foot mural of the Cat Stevens’ album cover for “Teaser and the Firecat” on a wall inside his fraternity house.

Career, marriage, children, grandchildren and life in general sidetracked Corrigan’s passion. But during the pandemic, he found himself with lots of free time. Lisa, his wife for nearly 46 years, suggested he take up painting again.

“Sitting home during the pandemic, you can only do so many crossword puzzles and jigsaw puzzles,” Corrigan said.

On Rockies road trips, the broadcaster spent much of his off hours in his hotel room and on the team plane working on his novels. Oil painting was never feasible until the last couple of years when he discovered water-soluble oil paints.

“Before that, there was just too much mess and cleanup to make it feasible on the road, so I just painted at home,” Corrigan said. “But then the new paints came out and Lisa bought me a portable easel for Christmas. Now I take it on the road with me.”

Corrigan’s first Rockies painting captures Coors Field after a thunderstorm, with swirling colors of orange and purple in an abstract flair. Other paintings are more true to life, with Corrigan striving to capture the essence of his subject. The portrait of Bud Black, for example, portrays the manager in a contemplative moment as he looks onto the field from the dugout.

“I’ve tried to do a combination of players and moments that tell the story of the team,” Corrigan said, explaining that he works off photographs when he paints. “I wanted it to be people and events who are the Rockies.”

He recently completed a painting of Kyle Freeland that captures the pitcher’s competitive spirit. Freeland, on the mound, is in the foreground. The background is an energetic, kaleidoscope of bright colors, a la LeRoy Neiman.

“It took some searching, but I finally found a photo that shows ‘Free’ giving that lion’s roar,’ ” Corrigan said.

Freeland got a look at the painting the other day in the Rockies’ clubhouse. Freeland asked Corrigan to have a copy produced so that he can hang it in his own home.

“It’s so cool,” Freeland said. “Jack has called so many Rockies games and for him to take time out of his day to paint one of those of me, for me, is an honor. I can’t thank him enough. The details of me — the colors, the energy — you could tell that he took a lot of time.”

Corrigan is self-taught and he admits that some aspects of painting are tough for him.

“I’ve always found it hard to paint hands,” he said. “And shadows. Shadows are tough and you’ll notice that baseball players have a lot of shadows on their faces because of the ballcaps. That’s why I need a great photograph to paint my Rockies pictures. The photos show me where the shadows are.

“And don’t get me started on trying to paint pinstripes, like the ones in Nolan (Arenado’s) painting. Those pinstripes are a pain in the you know what.”

Black, who’s come to know Corrigan quite well, said, “Jack is a man of many talents. Not only an accomplished, tremendous broadcaster, but you should see what he does with a paintbrush!”

As a radio broadcaster, Corrigan’s job is to paint a verbal picture of the game on the field. It’s not lost on him that he paints with both words and a brush.

“The bottom line: I’m a storyteller,” he said. “With my broadcasts and my books, and now with my painting. This is another way for me to tell a story. If you are given a gift to try and do tell those stories, it would be a shame not to take advantage of it.

“So, whether it’s not anything more than sprucing up the blank wall in a radio booth or a player or manager who wants a copy of my painting, it’s fulfilling for me.”
