Lack of power hitting making way possible for Asif Ali to make it into final 15 till deadline 23rd may which will final date to make changes in their squad for all teams. His quick fifty in 2nd ODI against England  he made 51 of 36 balls while chasing. Pakistan must know the importance of late power hitting in lower order. in the end of that match Pakistan comes very closer but still short fall of 12 runs. the 2nd ODI between Pakistan and England has simply given one straight indication that this world cup is going to be high scoring. pitches are designed flat and there is not lot of movement and no grass so there is nothing for bowlers and every team is looking for power hitters. in this case Pakistan is very behind. and they got to work on this because modern cricket is change and 300+  is now a conventional score in ODIs. however their achievements in 2nd ODI is credential but their overall performance is 5.26 is fourth worst (behind Srilanka, Bangladesh and Afghanistan) amongst teams participating in the world cup. These figures become more strange if you lift out the matches against Zimbabwe and Hong Kong to 4.88. issue become very thinkable when you put step into the event where the team like England most recently scored a record of 482 against Australia has hold the record of most runs in ODIs history.
If take a review of strike rate of Pakistans batsmen since champions trophy only Asif ali and Imad Wasim has strike rate of more than hundred 132 and 112 respectively and Fakhar Zaman is third best strike rater of 95.
Asif Ali is now the most necessarly contender for world cup as faheem ashraf with bowling allrounder also did not put any impact with bat and the situation would obously under the eye of selectors.
He does his case strong with that quick fifty against England in 2nd ODI.
