Wasim Akram (Urdu: wsym khrm; born 3 June 1966) is a former Pakistani first-class cricketer, cricket commentator and television personality. He is acknowledged as one of the greatest bowlers of all time. A left-arm fast bowler who could bowl with significant pace, he represented the Pakistan cricket team in Test cricket and One Day International (ODI) matches. In October 2013, Wasim Akram was the only Pakistani cricketer to be named in an all-time Test World XI to mark the 150th anniversary of Wisden Cricketers' Almanack.

During his professional career he bowled with genuine speed and hostility. Akram was a man possessed of accurate control of line and length, accompanied by seam and swing bowling skills, extended to both inswingers and outswingers. With a very quick bowling action, he could bowl equally well from both sides of the wicket. His mastery of reverse swing with the cricket ball meant he was at his most dangerous towards a bowling innings, and earned him the nickname of one of the "Sultans of Swing", the other one being Waqar Younis.  As well as often being able to find the edge of the bat, Akram would also focus his bowling attack on the stumps and had a particularly lethal inswinging yorker. Of his 414 Test wickets, 193 were taken caught, 119 were taken leg before wicket and 102 were bowled. In partnership with Waqar Younis, he intimidated international batsmen in the 1990s. Together Wasim and Waqar, known as "the two Ws" of the Pakistani team, were one of the most successful bowling partnerships in cricket.  With the bat he was especially effective against spin bowlers. However, he liked to slog and was criticised for his lack of high scores and giving away his wicket too cheaply. In October 1996 he scored 257 runs not out, of the team's total of 553 against lowly Zimbabwe on a typical flat South Asian pitch at Sheikhupura. He also achieved good scores for the Pakistan team such as his scores of 123 and 45* against Australia to take Pakistan to victory in a low scoring match. His batting was also valuable sometimes to the Pakistan ODI side, such as in the Nehru Cup in 1989, when needing six runs and two balls to win the match, he hit the first delivery he faced, from part-time off-spinner and batting legend, Viv Richards, for a six and secured the cup.  In December 2012 after Ricky Ponting announced his retirement he said that Wasim Akram and Curtly Ambrose were the toughest bowlers he had faced "Akram for the exact opposite, you could get a few runs off him, but you just knew there was an unplayable ball around the corner, be it with an old ball or with a new ball," - Ricky Ponting.
