The Pakistan all-rounder leads his beloved Red Rose county into the NatWest Trophy semi-final against Hampshire at Southampton tomorrow, one game away from leading them out at Lord's.
And he warmed up in style at sizzling Old Trafford yesterday, blasting an unbeaten 75 from just 42 balls to set up a crushing AXA League victory over Gloucestershire.
Wasim and Neil Fairbrother, who hit 75, were the key figures as Lancashire plundered 114 in the last 10 overs to post a formidable total of 222-6.
Fairbrother continued his consistent form either side of his recent ankle injury with his fourth consecutive one-day half century, while Wasim staged a near repeat of his amazing display against Notts in the Benson and Hedges Cup.
He hammered a career best 89 not out at Trent Bridge including five sixes and yesterday was a new Sunday League best for Wasim, and only his third half century in over 100 appearances, with three big sixes including one on to the tramline at the Warwick Road End.
``I thought he would at least have a look before hitting out, but he played some amazing shots right from the start,'' said a stunned Fairbrother.
``Neil complemented each other perfectly,'' added coach Dav Whatmore. ``Neil tried to give him as much of the strike as possible, and Wasim played some incredible shots.'' Gloucestershire never threatened the Lancashire total after two early wickets for Ian Austin, and all the other Lancashire bowlers got in on the act later on - except Wasim, who had already done his bit.
There were also two wickets each for Glen Chapple and Peter Martin, a welcome one for Mike Watkinson on his return to the first team and three more for Gary Yates to complete a wonderful week.
The win was Lancashire's eighth out of nine in one-day cricket, keeping them joint top of the AXA League with Essex and firing a warning to Hampshire, who were crushed by Kent.
Essex have a better run rate, 10.89 compared to Lancashire's 9.71.
``We have got into a winning habit,'' said Whatmore, ``and it's come at a good time.
``We are all looking forward to Hampshire.
``It's my biggest game since the World Cup final.''
