Pakistani bowlers are trying hard to defend the total and to me still it looks possible for them because already AUS lost 5 wickets and still need 50 more runs to win this match.
There is no issue with the required run rate so Pakistan need 5 more wickets to win and get into final or AUS just need to play sensible cricket from this point if they don't want to lose this match.
Australia U19 team did not start their innings well. After losing the first wicket for 33 runs, Australia lost four top-order batsmen to collect only 59 runs. But now Oliver Peake and Tom Campbell are batting brilliantly. Peake remained unbeaten with 43 runs and Campbell with 25 runs. At the end of 38 overs, Australia collected 145 runs. Australia need only 35 runs from 72 balls. Australia is in control of the match. But Australia cannot win if Campbell and Peake are out. I would say so far Pakistan has a chance to win. I expected some better batting from Pakistan batsmen.
