A very professional performance from pakistan, they have kept up the winning habit which is a help, and most of the bowlers and batters contributed in some way, which will assist them physically and mentally ahead of a difficult tour.
The match with England 'A' is very important as Pakistan are likely to be a lot less comfortable throughout the game - they will be favourites but against test quality players (the A team features several), you are going to have to battle through some sessions of pressure to win. This would only be good for Pakistan as they need to go into the first test knowing how to survive the pressure situations in this country; if all their tour games are cakewalks it could play into England's hands come Lord's, as Pakistan won't know what hit them if they come under pressure.
Pakistan don't want their best player (Inzy) and their most explosive player (Afridi) not to have their feet moving by the time the test series comes around, so they will hope they can get a start or two against England 'A' and get more of a batting workout. Otherwise, on the evidence of today Pakistan look well equipped to compete with England come the first test.
The selection of Hoggard for England 'A' is an interesting one. If he produces a match-winning display in the tour game, then Pakistan could be very scared of him throughout the test series which will play into England's hands and allow wickets to fall psyhcologically as well as from the quality of the bowling. However, if Pakistan see off his new ball bowling, get used to his rhythm and play him reasonably well, then it will play into Pakistan's hands as they will be ready for what I feel is the trump card in England's bowling attack (on current form) come 13th July.
