Mitch Marsh's incredible start to his Twenty20 captaincy career hasn't surprised Australian fast bowler Sean Abbott.
Marsh crunched an unbeaten 79 off 39 balls, which included six sixes, to steer Australia to an emphatic eight-wicket demolition of South Africa with 31 balls to spare at Durban on Friday night (Saturday AEST).
Forty-eight hours earlier Marsh thumped 92 not out in the Aussies' emphatic 111-run win in the opening rubber of the three-match series at Kingsmead, which Australia lead 2-0.
The Proteas have been powerless to quell Marsh, who has racked up 171 runs off 86 balls for the series without being dismissed.
"I think the way he's playing on the park is just the way he's been playing for such a long time now," said Abbott, named player of the match after capturing a T20I career-best 3-22 with the ball.
"To Mitch's credit he's quite a level personality, certainly amongst the group.
"He hasn't changed at all since stepping into the captaincy, albeit only two games and having only been on tour for a week.
"Not surprised at all that he's doing really well and flourishing in his first two games as captain.
"It's really good to see because he's such a great person, such a good team man and really cares about people around him."
Marsh received wonderful support from clean-striking opener Matt Short, who scored 60 at better than two-a-ball in his second international.
The pair's 100-run second-wicket stand was Australia's best in T20Is against South Africa and came in spite of less friendly batting conditions than the first match.
"The pitch tonight suited the bowlers," Abbott said.
"It might not have looked like that when we were batting but that just speaks volumes for the way those guys are batting at the moment."
After Tavemba Bavuma blasted 35 of South Africa's first 36 runs in the first three overs, Abbott's introduction into the attack swung the match Australia's way.
He dismissed the rampant Bavuma in his first over and Proteas captain Aiden Markram (49) in his last.
Abbott has adapted quickly to South African conditions following his recent county stint playing both red and white-ball cricket with Surrey in England.
"It can take a bit of adjusting but my job is to bowl," he said.
"When I'm standing at the top of my mark, I've just got to go out and do it.
"I'm quite used to that - it's part of being a cricketer, (playing) 12 months of the year.
"It's something I'm really enjoying."
