August, he was also named in the 16-man squad for the NatWest Series of One Day Internationals against Pakistan. Making his full international debut in a Twenty20 international at Bristol on 28 August, Yardy made an unbeaten 24 from 14 balls and took a wicket in debut. He went on to make his ODI debut against Pakistan at Trent Bridge in September, taking 3/24, the best figures by an England male spinner on ODI debut. In December, Yardy was not included in the England squad for the one-day series in Australia following a disappointing 2006 ICC Champions Trophy performance in India. He captained of the England A squad to tour Bangladesh in 2007 and in June was selected in the 14-man one-day squad for matches against the West Indies. After three years, he was recalled for the 2010 World Twenty20 in the West Indies. He was ever-present in the tournament, taking four wickets as England won the tournament, beating Australia in the final. Yardy was then recalled to the ODI side and was again ever-present in the early-summer series against Australia and Bangladesh. Although he only took four wickets in eight games, he proved to be economical at only 4.36 runs an over and scored his first international half-century, making 57 at The Oval against Australia. Yardy was selected in England's 15-man squad for the 2011 World Cup. He opened the bowling in a match against South Africa, just the second time a spinner had opened the bowling for England in ODIs but on 24 March it was announced that he had flown home from the competition suffering with depression. The competition were the last in his international career. In all he made 42 one-day appearances for England. Coaching career After his playing career ended, Yardy completed a sports psychology degree at Chichester University. He coached cricket at Hurstpierpoint College and in 2016 worked with Sussex's under-17 side. After working part-time with First XI players at the end of the 2016 season, Yardy was appointed batting coach at the club in February 2017. The club were clear that they considered he had made a "significant difference" to players. He became the club's Second XI coach ahead of the 2018 season. After two and a half seasons working at Sussex, during which time he had also coached the England under-19 side, Yardy left the club at the end of July 2019
