American golfer Daniel Berger has made waves this season, notably finishing 13-under at the Arnold Palmer Invitational and briefly holding a five-shot lead amid fierce competition, including from Rory McIlroy. A major factor behind Berger’s recent surge is his longtime caddie, Josh Cassell, whose partnership with Berger began in June 2020 and has flourished since, playing a crucial role in Berger’s game and confidence.
Since teaming up post-lockdown, Berger’s performance has shown remarkable improvement, including consistent top-25 finishes last year at the US Open, The Open Championship, and the 2025 Masters. These achievements signal more than just natural skill; Berger’s renewed focus and success are intertwined with his collaboration with Cassell.
Josh Cassell’s Extensive Experience as a Professional Caddie
Josh Cassell brings over 25 years of professional caddying experience to the greens. His career includes working alongside elite golfers such as Geoff Ogilvy, Billy Horschel, John Senden, and Jason Duffner. This deep reservoir of experience has enabled Cassell to develop keen insights that clearly benefit Berger.
Among Cassell’s memorable moments is the 2014 Valspar Championship win with John Senden. However, one of his most remarkable achievements came while caddying for Billy Horschel in 2017. After Horschel missed the cut at The Players Championship, Cassell confidently predicted a win at the AT&T Byron Nelson tournament the following week—a prediction that became reality when Horschel edged out Jason Day in a playoff.
This incident highlights Cassell’s passion and belief in his critical role. Reflecting on his motivation, Cassell said,
“Having the opportunity to make a difference in the player’s performance when trying to win a golf tournament.”

Daniel Berger’s Journey Back After a Challenging Injury
Daniel Berger’s path has not been without obstacles. In 2022, he faced a significant lower-back injury, including a disc bulge and bone sensitivity that forced him off the tour for 19 months. Determined to avoid surgery, Berger committed himself to rehabilitation and extensive training, gradually regaining strength and mobility. This difficult period took a toll, as Berger described, “My everyday life sucked,” during his struggle with persistent pain.
Upon his return in 2024, Berger chose to reunite with Josh Cassell to support his comeback. He also began working with new coach Mark Blackburn to refine his approach to the game. Berger noted the positive shift in his physical condition and mindset, stating,
“As the year went on, I felt better, which I’ve never felt in my seven or eight years before. At the end of the year, I was always feeling worse and tired. This year was the first year I’ve ever felt better,”

The Impact of Cassell’s Partnership on Berger’s Career
Prior to teaming up with Cassell, Berger had worked with other caddies such as Grant Berry and Lance Berry, with Grant Berry sharing in Berger’s FedEx St. Jude Classic victories in 2016 and 2017. However, the chemistry and understanding between Berger and Cassell has taken their work to another level since reuniting.
Their relationship is rooted not only in skills but also in trust developed during their early collaboration before Berger’s injury hiatus. With Cassell on the bag, Berger has demonstrated renewed determination and confidence, factors that are essential for competing at the highest level on the PGA Tour. This dynamic duo is proving to be a formidable force as Berger continues to ascend in professional golf.
Looking Ahead: What the Future Holds for Berger and Cassell
As Daniel Berger gains momentum in his career comeback, the partnership with Josh Cassell appears central to his prospects of winning more tournaments. With Berger’s improved health and Cassell’s veteran expertise, the duo is poised to challenge leaders in upcoming events and major tournaments.
Berger’s recent strong performances and steady rise signal promising times ahead, and with Cassell’s guidance, he could be a consistent contender for top honors. Fans and analysts alike will be watching closely to see how their collaboration continues to shape Berger’s success on the course.
