Three times a European Tour winner in 2015 – two of them before he had even experienced a major championship. Sullivan then became one of six rookies in Europe’s Ryder Cup side at Hazeltine and began it partnering Rory McIlroy, but it proved to be one of only two games for the former Walker Cup winner as America regained the trophy.
After turning professional in 2011 he had to return to the European Tour qualifying school a year later, but then improved his money list position from 145th to 98th, 33rd and then eighth after capturing the South African Open in a play-off against Charl Schwartzel, the Joburg Open by two shots and the Portugal Masters by a massive nine-stroke margin. He also finished runner-up to McIlroy at the season-ending DP World Tour Championship and on his return to Dubai three months later was second to Danny Willett at the Desert Classic.
Also in 2016 represented Europe in the EurAsia Cup and England in the World Cup alongside Chris Wood, while in 2014 a hole-in-one at the KLM Open earned him an unusual prize – a trip into space if he chose to take it. Joint runner-up at the recent Irish Open.
