Labuschagne, who was just two points behind Root before the two ICC World Test Championship (WTC) Tests completed over the past week, now enjoys a healthy lead at the top even as Root has slipped to fourth place behind Steve Smith and Babar Azam.
Cricket Australia confirmed that Smith, who had stepped down as Test skipper in the wake of a 'ball-tampering' controversy during a red-ball series against South Africa in 2018, will lead the Baggy Greens in the absence of Cummins.
Australian skipper Pat Cummins said that his side is extremely excited about the opportunity they will be receiving in the next few months to play some of the best teams in the world in their Test summer, that could also give them an opportunity to play the final of the ICC World Test Champi
Steve Smith scored his second fifty of the series before speedster Mitchell Starc and Adam Zampa bowled superbly to help the team secure a 72-run victory against England.
