Charlie Woods was impressive on the golf course in the first round of the PNC Championship on Saturday, but it was his trash-talking skills that really left a mark.

Charlie, who was playing with his superstar father Tiger Woods, had a message for Justin Thomas and his father Mike when one of their balls landed in the bunker. The 11-year-old's message was "Draw Hole!"

Justin Thomas revealed the meaning of the note after the round. He said his father was the one who left Charlie the note the day before.

"Charlie drove one through the fairway and my dad was playing in front of them, and he’d hit it through the fairway and into the trees," Thomas said, via the Golf Channel. "My dad wrote on a piece of paper ‘draw hole’ on it and put it under his ball. In typical Woods fashion, he kept the piece of paper, and when my dad hit it in the bunker he put the exact same piece of paper behind his ball."

Before the tournament started, it was Thomas who revealed the moment he knew Tiger Woods’ son was going to be a big deal.

"I was over at Tiger’s house, and us three were having a putting contest and we played nine holes, us three, straight-up, (Charlie) didn’t get any sort of advantage," he said. "I think he was 8 years old, 9 years old at the time. And it was one of the three combined total weeks I’ve held No. 1 in the world, around that time. And Charlie was leading going into the last hole.

"He was 2 under, I was 1 under, and I think Tiger was even or 1 under or something like that. Charlie was mouthing off, you know, he’s like, ‘Here I am, I’m 9 years old beating the No. 1 player in the world and supposedly the best golfer of all time.’ And he three-putted and I made it, so I beat him. And that shut him up pretty quick."
