DURBAN: A career-best unbeaten 92 from new captain Mitch Marsh propelled Australia to a comprehensive 111-run victory over hosts South Africa in the first Twenty20 International in Durban on Wednesday. Australia took a 1-0 lead in the three-match series after posting 226 for six in their 20 overs, the highest score at Kingsmead, before restricting South Africa to 115 all out in a reply that never really got going. The second match in the series is on Friday before it concludes two days later. All three games will be played in Durban. Both sides are missing several of their regulars. After being sent in to bat, Australia’s innings was anchored by Marsh, who reached his 50 in 22 deliveries. He put on 97 in 50 balls for the fifth wicket with Tim David, who had no trouble clearing the small boundaries with four sixes on his way to 64 from 28 balls. South Africa were sloppy in the field and at times battled to control line and length with the ball. Seamer Lizaad Williams was the pick of the home attack with 3-44 in his four overs. Opener Reeza Hendricks led a near lone challenge to Australia’s total with a well-constructed 56 from 43 balls, as the home side were pegged back by an excellent spell of 4-31 from debutant leg-spinner Tanveer Sangha. Seamer Marcus Stoinis pitched in with 3-18 in a fine display of swing bowling. Australia also handed debuts to opening batter Matthew Short all-rounder Aaron Hardie and fast bowler Spencer Johnson, while South Africa’s under-strength side included new faces in batter Dewald Brevis and seamer Gerald Coetzee. Brief scores Australia 226 for 6 (Mitch Marsh 92 not out, Tim David 64, Lizaad Williams 3-44) beat South Africa 115 (Reeza Hendricks 56, Tanveer Sangha 4-31, Marcus Stoinis 3-18) by 111 runs.
