Scottie Scheffler showed his trash-talking side that is legendary in Dallas circles and illustrates the ultracompetitive nature of golf's No. 1 player. Tom Kim expected no less. The Presidents Cup turned spicy Thursday when the 22-year-old Kim took his celebrations to another level after he buried a birdie putt from just inside 30 feet on the par-3 seventh hole.

The pair of friends had something to say to each other after they each drained birdie putts on back-to-back strokes.

Sure, the World No. 1 has shown a fiery side on the course before, but it's usually directed inward. Or, sometimes, directed at his caddie Ted Scott, which is nothing Teddy isn't used to as Bubba Watson's former bag man. Other than that, though, it often seems as though the two-time Masters winner would not hurt a fly.
