He was also a member of the Great Britain & Ireland Walker Cup team that year, before turning professional in September.

These victories helped him to finish 21st on the Order of Merit and climb into the top 100 of the Official World Golf Rankings for the first time in his career.

Dyson nearly won the season ending Volvo Masters tournament at Valderrama in 2007, when he was involved in a three-man sudden death playoff for the championship with Soren Kjeldsen and Justin Rose.

[5] This win elevated Dyson to 9th on the Race to Dubai list and earned him a place in the following week's WGC-Bridgestone Invitational.

In 2013 Dyson was disqualified from the BMW Masters for submitting an incorrect score after it was determined that he should have been assessed a two stroke penalty for tapping down a spike mark during the second round, in violation of the rules.

He was later fined £30,000 and given a suspended two-month ban from the European Tour after they determined that, although his actions were considered to be a serious breach of the rules, they were not premeditated.

[8][9] Dyson suffered a wrist tendon injury early in 2015 which ultimately required surgery and resulted in him missing much of that season.
