David Andrew Warner is an Australian cricketer. A quick-scoring left-handed opening batsman, Warner is the first Australian cricketer in 132 years to be selected for a national team in any format without experience in first-class cricket.His is noted for his aggressive play for New South Wales and Durham, and has earned a contract with the Delhi Daredevils in the Twenty20 Indian Premier League.

Warner is known for favouring the aerial route with his aggressive left-handed batting style, and ability to switch hit, using the back of his bat or by taking a right-handed stance. He is an athletic fielder and also a part-time spin bowler. His bowling style is unique in that he mixes off-spin bowling with his more usual leg-spin bowling. At just 170cms Warner generates his power from strong forearms and uses his low centre of gravity to get underneath deliveries and hit them high in the air. In a Twenty20 match for New South Wales in 2009, he hooked a six off Shaun Tait that landed on the roof of the Adelaide Oval, only a month after hooking the same bowler 20 rows back at the SCG.

Warner was signed by IPL team Delhi Daredevils for the 2009–10 seasons.During the 2009 tournament which was played in South Africa, Warner played in seven games, scoring 163 runs at an average of 23.28 and with a strike-rate of 123.48. His top score was 51.

Warner gave Delhi Daredevils some explosive starts in the second edition of the IPL when Virender Sehwag missed some matches due to injury. Warner's good form at the top forced Sehwag to come down the order in the rest of the tournament, though Warner was out for a duck in the semi-final against Deccan Chargers.
