I could excuse Warner with an opening batsman's strike rate of 66 in a run chase if this was 20+ years ago facing Ambrose/Walsh/Bishop/Wasim/Waqar/Donald on a bowler-friendly pitch in Australia (as was common in the '90s) with full-size boundaries/no ropes and bats less than half the width or so of his current Gray Nicholls.
But even though Bumrah/Kumar are very good-quality fast bowlers, strike rate of 66 on a batter-friendly wicket with much shorter boundaries than average, requiring 353 runs to win is simply unacceptable. And then running out Finch on top of that....Finch probably wishes he was still opening with Khawaja.
