Just days before stepping onto the tee at the 2026 3M Open, Muzzy Donohue faced a wrenching personal blow: the passing of his grandmother, Marcey. It was a raw moment that could have shattered the focus of any rookie debuting on the PGA Tour. Instead, it became a quiet source of strength fueling his unexpected surge through the weekend.
Donohue’s story is far from typical. At 25, he’s battled his way through mini tours after falling short at PGA Tour Latinoamerica Q School. Just two weeks before the 3M Open, he won the Minnesota State Open — an under-the-radar victory that earned him a sponsor’s exemption into his first PGA Tour event. What followed was a roller-coaster that delivered one of the more compelling debuts this season.
A Rough Start, Then a Breakout
His opening round 73 didn’t suggest much. But Friday was a different story. Donohue fired an eight-under 63, vaulting himself into contention, sitting just one shot behind World No. 1 Scottie Scheffler. The hometown crowd, many of whom are family, roared him on. He described the experience as “unreal” and admitted the gravity of playing his first PGA Tour event was hard to put into words.
Family Ties on the Bag
Adding an unusual twist was Donohue’s cousin Harrison, who doubled as his caddie — despite knowing “very little about golf,” as Donohue jokingly put it. Harrison wasn’t there to analyze swings or yardages but to keep Muzzy’s mind off the pressure. By sharing funny high school stories and simply being a calming presence, he helped Donohue avoid overthinking, a common trap for rookies trying to prove themselves.
Carrying a Legacy, Not Just a Bag
The tournament carried an emotional weight beyond the leaderboard. Donohue and Harrison often spoke about their late grandmother, drawing strength from memories during the round. Donohue marked his golf balls with her name and rubbed it for good luck — small rituals that grounded him amid the swirling pressures of a major debut. “She’s looking down on me and looking out for me,” he said with a mix of humor and sincerity.
