Marcus Trescothick quickly became frustrated, lofting Vaas to mid-on one ball after inside-edging an ambitious pull shot to the fine-leg fence, England's last boundary for 31 overs.
Then Krejza turned the match with two wickets in two balls, firstly uprooting the leg-stump of VVS Laxman with a ball than spun from outside off via the inside edge.
Unfortunately Luke Wright, who has faded since starting the tournament so strongly, mis-hooked RP Singh in only the second over and was comfortably taken by Yusuf Pathan inside the circle at fine leg.
