Virat played an unbelievable knock … I think 160 was around par, it just took an unbelievable innings to get India over the line.”Earlier, Australia got off to a quick start as left-handed opener Usman Khawaja began the innings with a pulled four off Ashish Nehra and then took four fours off the following over from Jasprit Bumrah to finish with a 16-ball 26 comprising six fours.Australia raced to the 50-run mark in only 3.4 overs as Aaron Finch (43 off 34) smashed two consecutive sixes over long on off spinner Ravichandran Ashwin but the scoring rate was checked as wickets fell at regular intervals.”It was a tough score, they got 60 runs in the first six overs,” Dhoni said.Australia reached the 100-run mark in 12.5 overs and 150 in 19.4.The opening stand was worth 54 and ended in the fifth over when Nehra induced an edge to dismiss danger man Khawaja.David Warner (6) and Smith (2) fell to spinners Ashwin and Yuvraj Singh respectively with Dhoni having a hand in both dismissals.Ashwin’s single wicket Sunday made him the first Indian to take 50 wickets in T20 internationals while wicketkeeper Dhoni’s three victims brought him level on 60 with Pakistan’s Kamran Akmal for dismissals in T20 internationals.Glenn Maxwell chipped in with a useful 31 that included a reverse-sweep six off Yuvraj SinghShane Watson made an impressive exit from international cricket as he followed up his unbeaten 18 with 2-23 in four overs and a brilliant diving catch at cover to dismiss Yuvraj off Faulkner.
