Bowling all-rounder Wharf was a product of Yorkshire’s Academy but despite making his county debut in 1994 he struggled to make a first-team breakthrough and moved to Nottinghamshire three years later.
He made an unbeaten century in his first appearance for the second XI but was released in 1999 and snapped up by Glamorgan. He made an immediate impression with the Welsh county and was named as their Young Player of the Year in his first season.
Injury plagued him for the next two seasons but he shone with both bat and ball in 2003 and 2004 and was a vital member of the Glamorgan side which won the 2004 totesport League and reached the semi-finals of the Twenty20 Cup.
He was rewarded with a place in England’s provisional 30-man squad for the ICC Champions Trophy and although he missed out on final selection, he was eventually called up due to an injury to Kabir Ali.
Wharf's place was never in doubt after his stunning debut in international cricket which saw him take 3-30 and win the man-of-the-match award in the NatWest Challenge opener against India at Trent Bridge.
He dismissed Rahul Dravid in the next match and finished with 2-41 in the final game. Although he failed to repeat that success in the Champions Trophy, he featured in all four games as England reached the final and was named in the one-day squads to tour Zimbabwe and South Africa.
The winter programme began well for Wharf and in the second one-day international against Zimbabwe in Harare he recorded the best figures by a Glamorgan bowler playing for England.
His return of 4-24 from six overs in a 161-run victory beat Steve Watkins' previous record of 4-49 against West Indies in 1993/94.
Wharf featured in all four matches as England won the series 4-0 but was then initially left out of the side in South Africa due to the form of Matthew Hoggard, whose impressive performances in the Test series secured a recall in the limited-overs game.
Wharf was recalled for the sixth ODI and impressed with three wickets, including the dismissals of Graeme Smith and Jacques Kallis in the space of two balls.
Two more wickets followed in the last match of the tour at Centurion but he could not prevent England losing the series 4-1.
He was named in the 25-man England Development Squad in May 2005 and was awarded a new three-year contract with Glamorgan in July, keeping him with the county until the end of the 2008 season.
Wharf was also chosen in the England squad for the Hong Kong Sixes in 2005 and the England A squad for the spring tour of the West Indies the following year.
He struggled to find his best form for Glamorgan in 2006 but was more consistent in 2007 when he hit a career-best 128 not out against Gloucestershire in the County Championship.
In 2008 Whatf fared better in limited-overs cricket than the four-day game and was awarded a benefit season in 2009, a season which proved his last given he announced his retirement at the conclusion of the campaign.
