Watch: Robert MacIntyre claims emotional first PGA Tour win with dad as caddy

With Robert MacIntyre in between caddies, he made an emergency call to his father on Saturday, whom he admitted was out of his depth. Nevertheless, he was on the bag for his son for the first time since 2018.

"I'm a grass cutter," Dougie MacIntyre told CBS Sports.

Robert MacIntyre, now eligible for the Memorial Tournament, U.S. Open and Travelers Championships, confirmed that his dad won't be caddying for those big events. But that didn't take away from the unbelievable moment, saying, "I wanted this for my dad."   

"I'm crying with joy but laughing because I didn't think it was possible," Robert MacIntyre said.

Sunday was a day for caddies, apparently.

Earlier in the day, a fan jumped into action following an injury to C.T. Pan's caddy. Self-professed "golf nut" Paul Emerson took over duties for two holes before being relieved.
