Oli is a DP World Tour professional, coach and broadcaster, with more than two decades competing at the highest level of golf. He is a two-time Tour winner, eleven-time runner-up, and former Ryder Cup, Seve and Royal Trophy team member with over 100 weeks in the World’s top 50.

Born in Mansfield, Nottinghamshire, England, on 14th September 1980, Oli's golfing career began as a junior at Oakmere Park GC and later Coxmoor GC, competing at county and then international level for England boys. This earnt him a scholarship at Augusta State University where he went on to become the No.1 ranked collegiate player in the US, turning professional in 2003 after victory with Great Britain and Ireland at the Walker Cup.

Having ranked 15th on the Challenge Tour in his first year as a pro, Oli joined the European Tour in 2005, posting three top ten finishes during his rookie season. A runner-up on three occasions over the next two years, he enjoyed victory at the Seve Trophy for Great Britain and Ireland in 2007.

Four more runner-up spots, including the BMW PGA Championship, and an 11th place finish on the European Tour in 2008 earned Oli a place on the European Ryder Cup team, the first person in history to qualify for either team without a professional victory. He came back from four down with partner Henrik Stenson to beat Anthony Kim and Phil Mickelson.

In 2009 Oli ranked 33rd in the World. Another victory for Great Britain and Ireland at the Seve Trophy and six top ten finishes, including two in WGC events and two more runner-up spots at the Alfred Dunhill Links Championship and the HSBC Champions, saw him end the season ranked 7th on the European Tour.

Six more top tens followed over the next few seasons plus victory in the team and individual events at the 2011 Tavistock Cup.

Following a period off the Tour, over 200 starts including nine runner-up finishes and a sponsor’s invite, Oliver was finally able to celebrate an emotional maiden Tour victory at the 2014 Alfred Dunhill Links Championship at the 'Home of Golf', St. Andrews, Scotland.

In 2018 Oli secured two victories on the Challenge Tour, finishing 17th on the Race to Ras Al Khaimah and regaining partial European Tour status for the 2019 season.

Playing from limited starts in 2019, he posted four top five finishes including a career tenth runner-up spot at the Qatar Masters. A further top ten finish at the British Masters helped Oli regain his full European Tour card, finishing 66th on the Race to Dubai.

Almost eight years after his first Tour victory, Oli holed two enormous birdie putts on the back nine on Sunday to win the 2022 Made in HimmerLand by one shot and claim his second Tour title.

In 2023 Oli earnt his eleventh career runner-up spot at the British Masters on his way to retaining his full European Tour card for the 2024 season.

2025 was a year of adjustment for Oli. After over 20 years on tour, he chose to change some long-established routines in order to spend more time at home with his family. A reduced playing schedule created the opportunity to expand his work in golf media, continuing his contributions with BBC 5 Live at the majors and Ryder Cup, whilst also taking on a full-time broadcasting role with TNT Sports. It also allowed him to begin working more regularly in coaching and bespoke events.
