From there Wilkinson went on to win national and overseas tournaments and represented Great Britain in the World Championships at all junior age groups.

On the main Tour Wilkinson played some of his best tennis at Wimbledon where he reached the 3rd round in Singles on four occasions and made the quarter finals of Doubles.

He will probably be best remembered for his Centre Court battle in 1993 against Stefan Edberg, in which he broke the champion's serve no less than seven times before faltering on his own and succumbing to defeat in three close sets.

Wilkinson retired from the main tour in 1999 but kept up his competitive play in the following years and in 2005 became the British and world over-35 champion.

In February 2018, he was appointed as County Performance Manager for Hampshire and Isle of Wight LTA.
