Who are the top 3 players at the John Deere Classic?

Ben Griffin has been nothing short of relentless in 2025, already racking up 22 starts before arriving at the John Deere Classic. He’s currently sixth in the FedExCup standings, thanks to two victories and an impressive streak of six consecutive top-15 finishes, including a T13 at the Rocket Classic. He finished tied for fifth in his John Deere debut last year, and with his form this season, he heads into the week as the man to beat.

Fresh off a T25 finish at the Travelers Championship, Kevin Yu took last week off and returns rested and ready. The 25-year-old has two top-five finishes in his last four appearances and has looked right at home at the John Deere Classic, with finishes of T6 and T20 in his first two starts. A strong fit for the course, he enters with plenty of strengths to draw from.

J.T. Poston has shown a clear affinity for TPC Deere Run. He notched one of his three career PGA Tour wins in 2022 and has carded 13 consecutive rounds in the 60s at this venue. Known for his strong finishes on Sundays, he’ll be a threat from start to finish this time around.
