Australia clinched a knife-edge fifth Test against India in Sydney by six wickets to seal a riveting series 3-1 Sunday and book their place in the World Test Championship final. India were dismissed 45 minutes into the morning session of day three for 157, adding just 16 to their overnight 141-6 with the irrepressible Scott Boland ending with 6-45 and 10 wickets for the match. Set 162 to win, the hosts reached the target before tea against an attack missing injured strike bowler Jasprit Bumrah to regain the Border-Gavaskar trophy for the first time since 2014-15. Australia lost three wickets before lunch to leave the Test finely poised, including Steve Smith who agonisingly fell just one short of becoming only the 15th player and fourth Australian to reach 10,000 Test runs. But Usman Khawaja hit a composed 41 before Travis Head (34 not out) and debutant Beau Webster (39 not out) steered them home. “This is unreal, this (a series win against India) is one that a few of us didn’t have. It’s been an amazing series … it’s really lived up to all the hype,” said Australia skipper Pat Cummins. “I’m immensely proud. I love playing with these guys, they are such a special group. I feel privileged to have this job and what we have been able to achieve together. “Pretty satisfied at the moment.” Victory was enough to ensure Australia will defend their World Test Championship in the June final at Lord’s against South Africa. It culminated a thrilling tour full of twists and turns that saw record crowds and some spectacular individual performances. The five-Test series witnessed the emergence of exciting young talents in the form of Australian opener Sam Konstas and Indian all-rounder Nitish Kumar Reddy. At the same time, ageing veterans, notably Rohit Sharma, showed that the clock is ticking on their careers. India won the first match in Perth convincingly before Australia bounced back in the day-night affair at Adelaide. The rain-hit Brisbane clash ended in a draw before the hosts took all the momentum into Sydney with a pulsating day-five win in Melbourne. Indian pace spearhead and skipper Bumrah, who has been dealing with a back issue, batted briefly when his team resumed after bowling just one over and leaving the field on Saturday. But in a huge setback the 31-year-old did not appear again, leaving Mohammed Siraj and Prasidh Krishna to lead the bowling attack, with Virat Kohli in charge. “A little frustrating but sometimes you have to respect your body, and you can’t fight your body,” said Bumrah. “The whole series was well fought,” he added. “Younger players have come in, and the learnings will help us in future. They have gained a lot of experience and they will go from strength to strength. “It is all about adapting and learning.”
