he finished undefeated on 103 from 95 balls in a game which produced top notch entertainment for sky sports.
wessels said: “i’ve been a bit dry for runs of late so it was quite nice to ease a bit of pressure and play freely.
“it was a good wicket, we probably dragged it back towards the end and they were maybe disappointed they didn’t get crack on and get a few more but we were happy to chase it down and hopefully there’s more to come.
“it was fergie’s third hundred in eight games for worcestershire. he’s a fantastic player. he only landed last week and he’s straight in with an unbeaten hundred.”
on reaching the knock-out stages, wessels said: “at this stage you want to keep playing as often as you can and you have to keep winning if you want to win tournaments, so keep them coming.”
