For those observing him for the first time in his PGA Tour career, Koivun employs a putting routine developed by Mark Egly in the 1980s. Egly himself used this method during his final PGA Tour appearance at the 1995 John Deere Classic.
The accompanying video features Victoria Grasso, a three-time Iowa State high school girls’ golf champion and current head women’s golf coach at the NCAA Division I University of Nebraska Omaha. Filmed more than twelve years ago, the footage demonstrates her ability to hole consecutive putts from approximately fifteen feet by applying this straightforward visual method that emphasizes the eyes.
In his teaching, Mark Egly consistently stresses the critical role of the eyes. The drill illustrates how he aligns three objects for his players: the putter, the ball, and the cup. When the putter is placed directly beside the ball, the putter head and ball effectively become a single object, leaving the hole as the second point of focus. Egly maintains that aligning three objects is more effective than aligning only two. Observation of the drill used by Victoria Grasso makes clear why Jackson Koivun applies the same principle to align his putter with his intended line.
Congratulations to Jackson Koivun on his victory today on the PGA Tour and on reaching another significant milestone in his professional career.
