Paul Casey and Peter Kostis have mutually decided to end their 24-year partnership, with the former’s relationship with LIV Golf seemingly playing a part in the split
Phil Mickelson expressed his admiration for fellow LIV Golf star Paul Casey and his long-time coach Peter Kostis, following the end of their 24-year partnership over the weekend.
Casey, who boasts three PGA Tour titles and 15 DP World Tour victories in his career, had been working with Kostis since the turn of the century. However, Kostis confirmed their separation on social media, tweeting: “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.”
Under Kostis’ guidance, Casey established himself as one of the top golfers globally, reaching as high as third in the Official World Golf Ranking (OWGR). In 2022, the Englishman decided to switch gears by joining LIV Golf, following the path of Mickelson and others.
Phil Mickelson took to social media to heap praise on his fellow pros, remarking: “What a long and successful partnership you have had together,” in response to a post from the renowned coach. “Congratulations to you both.”
Paul Casey’s career has soared with the help of coach Kostis, achieving triumphs across the PGA Tour and DP World Tour. Despite their successes in America and Europe, Casey’s allegiance has shifted to the controversial LIV series over two years ago.
It wasn’t long after his switch that Casey joined forces with the U. S. Open champion Bryson DeChambeau at Crushers GC. Together, they powered their way to victory at the LIV Team Championship held in Miami, making waves a year back.
Although the Crushers didn’t manage to secure back-to-back titles, faltering at the semi-finals to IronHeads in Dallas last month, Casey’s performance throughout the 2024 LIV season was commendable, landing him the 11th spot in the league rankings. Topping off his highlights was an intense showdown in Hong Kong where he finished runner-up alongside Cam Smith, narrowly missing the top spot to Abraham Ancer after a nail-biting playoff.
