Youngest player to score a century in both innings of a Test match

Aged 20 years 98 days, Australian opening batsman Phillip Hughes (b. 30 November 1988, d. 27 November 2014) became the youngest cricketer to score a century in both innings of a Test match when he hit 115 in the first innings and 160 in the second innings during the 2nd Test against South Africa at Kingsmead, Durban, on 6 and 8–9 March 2009. Hughes' innings of 160 was completed on 9 March 2009. Overnight on 8 March 2009, the day he set the record, he was 136 not out. His first innings score of 115 was completed on the first day of the match, 6 March 2009.

Hughes took the record from George Headley (b. Panama, 30 May 1909, d. 30 November 1983), who was 20 years 271 days after scoring 114 and 112 for the West Indies against England in the 3rd Test at Bourda, Georgetown, British Guiana (now Guyana), between 21 and 25 February 1930.

Hughes' 2nd Test heroics came against one of the most potent and feared bowling attacks of his generation, with pacemen Dale Steyn, Makhaya Ntini, and Morne Morkel and legendary all-rounder Jacques Kallis playing for South Africa, who were less than six months away from becoming the ICC's (International Cricket Council's) top-ranked Test-playing nation - the first team other than Australia to be No.1 since the ICC started its Test Championship in June 2003.

On 11 July 2013, Hughes and Australian teammate Ashton Agar set the record for the highest 10th-wicket partnership in a Test match (163 runs), during the 1st Test of the 2013 Ashes series against England at Trent Bridge. The record remained intact until it was beaten England's Joe Root and James Anderson 12 months later.

Hughes died as a result of a head injury suffered while batting in a Sheffield Shield match for South Australia against New South Wales at Sydney Cricket Ground on 25 November 2014. He had scored 63 runs in South Australia's first innings when he was struck on the side of his head by a bouncer from paceman Sean Abbott, despite wearing a helmet. Following surgery and a decision to put him in a medically induced coma, Hughes remained in a critical condition and died two days after suffering the blow. The current round of matches in the Sheffield Shield, Australia's premier first-class cricket competition, were abandoned as a mark of respect.
