It could have gone horribly wrong for Australia, the five-time champions, against Sri Lanka in what experts billed as a must-win game for either side. Sri Lanka, the 1996 champions, opted to bat first in the 14th match of the ICC Cricket World Cup 2023 on Monday. On a tricky Ekana Stadium top, Lankan openers Pathum Nissanka (61 off 67) and Kusal Perera (78 off 82) defied Aussie attack to post a 125-run opening stand in just 21.4 overs. Then, as narrated earlier, they imploded even as Lucknow braced for a storm mild but strong enough to leave a falling roof in its wake at the venue. A brief stoppage, and then Adam Zampa completed a four-wicket haul as Sri Lanka managed only 209 all out in 43.3 overs. The chase got off to a nervy start, and Lankan bowlers, especially Dilshan Madushanka who got both David Warner and Steven Smith in the same over, intimidated the Aussie batters. At one point, the Aussies were 81/3 (14.3). But the Lankan defence, a fraught one as it turned out, didn't last long. Mitchell Marsh found his lost touch before eventually running himself out for 52 off 51. Marnus Labuschagne (40 off 60) and Josh Inglis (58 off 59) also played brilliantly, but their efforts were overshadowed by what Glenn Maxwell (31 not out off 21) and Marcus Stoinis (20 not out off 10) did towards the end. With the five-wicket win, Pat Cummins's team opened the account while Sri Lanka, now led by Kusal Mendis, remained winless. Australia next meet Pakistan in Bengaluru on Friday, while Sri Lanka will stay back in Lucknow for their Saturday fixture against the Netherlands. Catch highlights of the AUS vs SL cricket match.
