Phil Mickelson shares heartfelt reaction as fellow LIV golfer splits with his coach of 24 years
Phil Mickelson shared a heartfelt message after his fellow LIV golfer Paul Casey parted ways with his longtime coach, Peter Kostis. The English golfer had been working with Kostis since he turned professional in 2000. The two enjoyed a strong bond and a successful journey together.
After 24 years, however, Paul Casey and Peter Kostis decided to part ways. Kostis recently announced the split on his X (formerly Twitter) account, explaining that the reasons for the separation are “both personal and private.” He wrote:
"Every teacher/student relationship has a half-life. Long term relationships are getting rarer and rarer these days and I'm proud of the number of students I've had for 10-15-20-30 years and even longer in a few cases! Reluctantly, after 24 years I feel it's best for me to step away from my work with Paul Casey. My reasons are both personal and private and will remain as such. Helping him become an elite ball-striker and world class player from the days he left ASU all the way to today was a very rewarding journey and I wish him well going forward.
Phil Mickelson commented on the post, sharing a heartfelt message in which he praised the "long and successful" partnership between Casey and Kostis. He wrote:
"What a long and successful partnership you have had together. Congratulations to you both."
Under Kostis’ guidance, Paul Casey has had a successful career since turning pro in 2000. Casey has competed on the PGA Tour and European Tour before joining LIV Golf, and he also plays on the Asian Tour. The English golfer has won 21 professional events, including three on the PGA Tour, and reached a career-high ranking of No. 3 in the Official World Golf Rankings.
Peter Kostis is a renowned golf instructor who has worked with several golfers over the years. He has an academy named Peter Kostis Learning Academy at Grayhawk Golf Club in Scottsdale, Arizona. He has worked with professional golfers including Bernhard Langer, Chez Reavie, and Mike Schmidt.
