Australia 3 for 386 (Warner 200* Smith 85) lead South Africa 189 (Jansen 59, Verreynne 52, Green 5-27) by 197 runs
Melbourne: David Warner's double hundred propelled Australia to 386/3 against South Africa putting them in command at the end of the second day of the Boxing Day test at Melbourne.
David Warner had an anticlimactic end to his superb day at the Melbourne Cricket Ground (MCG) as he retired hurt after having suffered a hamstring cramp during his double-hundred celebration.
The southpaw fell to the hot weather conditions at MCG after piling misery on the Protea bowlers as he shattered records en route to his knock of 200* runs.
Australia resumed their inning at 45/1 with David Warner 32* and Marnus Labuschagne 5* at the crease.
The duo could add only 30 runs to the scoreboard before the right-hander was run out for 14 runs.
Steve Smith walked into bat at number four and stitched a marathon partnership with Warner to put the hosts ahead in the game.
The duo shared a 239-run stand for the third wicket to render the visitors hopeless as they looked for the elusive wicket.
Warner played the role of the aggressor as Smith played second fiddle in the partnership.
The pair was brilliant between the wickets and kept the Protea bowlers at bay.
Smith missed out on a well-deserved century and was dismissed by pacer Anrich Nortje for 85 runs.
Left-hander Travis Head walked in at number five and played a quick-fire inning, taking the aggressive route from the beginning. He was partnered with Cameron Green initially but a blow to the all-rounder's finger saw him retire hurt and Alex Carey partnered him till the end of the day.
Head remained unbeaten at 48 (48) while Carey scored 9*(22) at the end of the day.
Australia ended the day with 386/3 with a sizeable lead of 197 runs.
