His first One Day International was in 2001, as England beat Zimbabwe by 5 wickets. Whilst not batting, he did take 2-33 off 9.1 overs with the ball. This was his first 'international' encounter, although he bowled Mashonaland to victory against England on their tour of Zimbabwe in 1996/1997. Later in 2001, he received the NBC Denis Compton Award.
He made his Test debut in 2003 against South Africa, as England won by 70 runs. He contributed 4 with the bat over the two innings, facing 54 deliveries. He had more success bowling and took 2-80 in the first innings, off 31 overs - an economy of 2.58 and 6-34 in the second innings, off 16.2 overs. He first trapped Graeme Smith lbw for 5, then Jacques Rudolph lbw for a duck, leaving the Proteas 28-2. Next, he clean bowledNeil McKenzie for 11, snaffled Andrew Hall for 0 and caught and bowledPaul Adams for 15. Finally, he dismissed Mark Boucher for 52, as the South Africans crumbled for 131. Finishing with match bowling figures of 8-114, Kirtley was awarded the player of the match award.
2003–2004
Kirtley represented England on three more occasions. After an excellent debut, he was included in the team that again faced South Africa in August 2003. He chipped in with twelve over two innings with the bat, and took 5-145 with the ball, although The Proteas ran out winners by 191 runs. The third and fourth matches of Kirtley's four match Test career were against Sri Lanka in December 2003. The first game was drawn, with Kirtley taking 2-109 and 2-62, and hitting 3 not out in the first innings. The second encounter was won comprehensively by Sri Lanka, by an innings and 215 runs. England batted first and scored 265, with Kirtley scoring 1. In their reply, the Sri Lankans amassed 628, with all bowlers struggling. Ashley Giles took two wickets at the cost of 190 runs and Gareth Batty conceded 137 with no reward, making Kirtley's return of 2-131 look distinctly presentable. In their reply, England were dismissed for 148. Despite this batting failure by the team, Kirtley hit 12, his best ever score in a Test, off 25 deliveries, including a six, before being bowled by Muttiah Muralitharan.
Twenty20 career
He bowled the first ever t20 ball, against Hampshire at the Rose Bowl. Kirtley was a surprising selection in the England squad for the 2007 World Twenty20 in South Africa, he was named alongside other specialists Darren Maddy, leg spinnerChris Schofield and veteran off spinner and former spin coach Jeremy Snape. Kirtley played one match against Australia.
Bowling
At his best, he was a skiddy bowler with good accuracy, and an excellent cricketing brain. At his worst, he was banned from bowling because of doubts about his action.
County career
In the 2006 C&G Trophy final, Kirtley bowled Sussex to victory with match figures of 5-27. His last match for Sussex before retiring from professional cricket after a sixteen-year career, was a Pro 40 one day match against Surrey on Saturday 4 September 2010 at Hove. His final victim was England batsman Kevin Pietersen as the match ended in a tie. Kirtley's figures were 3-61.
