Let's explain: Horschel played his college golf for the Florida Gators, so he knows plenty about the wildlife on courses in the Sunshine State — including, yes, alligators.
So when a gator made its way onto the course at PGA National on Thursday, Horschel knew exactly what to do.
The Florida native grabbed a 60-degree wedge, poked at the reptile and got it to retreat back to the water. And he made it look easy.
"I'm not afraid of gators," Horschel said.
"Listen, as I tell most people, I said, they're more afraid of you. The majority of the time they're only going to come after you during mating season where they're a little aggressive and then if you're around their nest when they've got some eggs. The majority of the time, they're fine."
Horschel had just finished playing the sixth hole at PGA National, his 15th hole of the day in the first round of the Cognizant Classic.
As he was walking to the next tee, he saw the gator crawling about and a police officer was trying to shoo it away with no success.
"He was going nowhere good," Horschel said. "So, I just went over there, helped the cop."
Horschel said he wondered if the officer was going to use a Taser to try and distract the gator.
Fortunately, a golf club did the trick just fine.
Horschel walked up to the right side of the gator and used the blade of his wedge to basically poke its shoulder, getting it to change course.
The gator got the hint and veered back to its left. Horschel followed the gator across the grass, watching it head directly to the water. The whole exchange took about six seconds.
"I grew up with my dad grabbing their tail when they're on the side of the bank and shooing them back in the water," Horschel said.
"I never touched a tail with my hand but I've done it with a club. Not that big of a deal."
Horschel ended up shooting a five-under 66.
Or we could put it this way - he had four birdies, one eagle and one gator.
