The same can't be said for the New Englander's burgeoning career as a bare knuckle boxer.

Gigliotti fought as a boxer from 2019 to 2023, building a record of 9-5 (5 KOs). To put that in baseball terms, Gigliotti's career fell off a table like a Pedro Martinez curveball once he couldn't properly hit the likes of Tiger Johnson and Mike Ohan.

His second act as a bare knuckle boxer, however, has been a grand slam so far, as the slugger appears to be lefty David Ortiz and righty Manny Ramirez wrapped into one.

Gigliotti has lived up to his nickname of "Harry The Hitman" en route to an undefeated record in six fights. The success has led him to a home-run homecoming, as the 31-year-old from Haverhill, Massachusetts, will headline at Boston's famed Fenway Park, home of the Red Sox, on Saturday for Bare Knuckle Boxing Championship 92.

Gigliotti (6-0, 5 KOs) won't be swinging at a cellar dweller, however. Standing across from him will be 145-pound champion Kai Steward (9-0, 2 KOs), whose waxed handlebar mustache makes him look like the second coming of "Boston Strong Boy" John L. Sullivan, who became the first heavyweight champion of the gloved era after fighting primarily with bare knuckles.

"I'm a diehard Boston Red Sox fan and have been to nearly a hundred games, with the first one being in 2004, the year the Red Sox beat the curse and won the World Series," Gigliotti told The Ring. "Fenway Park was my favorite place to go as a kid, and it's a dream to be headlining there and fighting for the BKFC championship on Saturday."

Gigliotti is a fourth-generation boxer of Italian and Irish descent. He was once a runner-up in the New England Golden Gloves and fought on a Canelo Alvarez undercard, but he only recently realized that ungloved fighting is where he excels.

"Bare knuckle boxing has been my true calling; it just took a little while for me to get into it," Gigliotti said. "I've been around the block. I like fighting, and here I am now.

"I've grown up around this, so this is nothing new to me. My family lived next to Mickey Ward's house. My cousin Jeff 'Hell Raza' Fraza was on 'The Contender' series before passing away in 2012, so I always dedicate my fights to him."

Gigliotti is just the latest example of a former pro boxer crossing into the bare knuckle boxing scene and performing exceptionally well.

"Fighting in bare knuckle is still very technical like boxing, but it takes a lot more grit," Gigliotti said. "I utilize my jab, which is my bread and butter, and dig into the body. I know the sweet science, and how to cut off a ring. In bare knuckle, I can split them up wide open with a double jab and cause some serious surface damage. And once I smell blood, it's over."

As the sport continues to enjoy a steady rise in relevance, the occasion is also a watershed moment for David Feldman, BKFC founder and president.

"I started BKFC with one fight and four people in attendance in a warehouse outside of Philadelphia," Feldman told The Ring. "I did the next fight with about 20 people and two fights. And we've grown this thing from warehouses, then to ice skating rinks, smaller arenas, and now, we're at Fenway Park about to put on a show in front of nearly 16,000 people and have our partner, Conor McGregor, alongside us promoting the show."

Fenway Park has seen its fair share of fights in the boxing ring featuring the likes of Jim Braddock, Tony DeMarco and Kid Chocolate, and in unsanctioned combat on the diamond between the Red Sox and Yankees.

But from 1956 until last year, the stadium didn't host a boxing match until Nolan Bros. Boxing brought a show back to the ballpark. They staged another event at the stadium in June.

"We grew and built a sport in bare knuckle boxing while overcoming so many different hurdles regarding perception and regulation, and here we are now," Feldman said. "For BKFC, it's go big or go home. We've sold out shows at some amazing venues, but nothing compares to Fenway Park. It's the most iconic feeling that we could really ever have, and I hope other boxing promoters follow us too, because we really want everyone to succeed."

Fenway Park will be staged for the ring to be on home plate and for fans to be watching from the seats between first and third base. The iconic, 37-foot-tall Green Monster in left field will be used for a screen.

For Gigliotti, the homecoming is a monster occasion in itself. He's expecting to have nearly 1,000 of his friends, family and fans in attendance on Saturday.

"I worked my ass off to get here, and it's a special time to showcase my hard work," Gigliotti said. "It's another fight, but it's a big opportunity. I have a lot of support around me right now, and my career keeps growing. My work ethic will prove that I am ready for this moment.

"I probably won't have to ever buy another drink in town if I win this fight and become the BKFC champion."
