Andrew Chafin is a one-of-a-kind character in the Cubs bullpen.

Between the long, curly locks, the mustache and his social media prowess, Cubs fans have really taken to the left-handed reliever.

Before rain swept away Monday night’s game, Chafin gave Marquee Sports Network a peek behind the curtain as he wore a microphone during batting practice and chatted with the broadcast trio of Jon “Boog” Sciambi, Jim Deshaies and Rick Sutcliffe.

Wearing a “FAILED STARTER” T-shirt from Obvious Shirts, Chafin showed off his speed and conditioning during the segment, tracking down fly balls and making some acrobatic throws.

“It’s like the only opportunity throughout the day where I can come out here and at least pretend to be an athlete for a minute, just tracking down fly balls, get a ground ball, field it on the run, jump throws,” he said. “Get a chance to have fun and if I screw up, it don’t matter.”

Chafin had some fun at his own expense, joking that the hardest part about being a reliever is the long jog in from the bullpen to the mound.

He also provided his opinion on bullpen carts and why he would never ride out to the mound on his horse.

“I think my horse would take a step out of that door and just have heart attack and flip over,” Chafin said. “Especially with all these people hootin’ and hollerin’ here.”

The 30-year-old only made 4 appearances with the team down the stretch last season and re-signed with the Cubs over the winter. This season, he has emerged as one of David Ross’ most trusted relievers out of the bullpen with a 3.46 ERA, 0.92 WHIP and 4 holds.

“This is like the first time in my career where I come running in the game and they actually cheer for me,” he joked.

There was plenty of gold from the entire mic’d up segment, including:

—Grooming his glorious mustache
—Who he is most often compared to in appearance, including Will Ferrell and John C. Reilly
—A subsequent “Step Brothers” reference, complete with perfect delivery into the camera
—The story behind the “FAILED STARTER” shirts
—Why he lived on his boat at the start of the season

And a hilarious interaction after Sutcliffe asked if Sciambi could hang out on Chafin’s boat:

Chafin: “You got cold beer?”
Sciambi: “Yeah I do.”
Chafin: “You show up with that, we’ll be good to go.”
