Wiltshire'S 50-plus side ended the season with another loss, having only won one match.
Batting first at Warminster against Hampshire, Wiltshire started slowly.
Stan Rudder once again bowled excellently with a spell of 1-8 off nine overs. But it was Yorke, with 4-26 off seven overs, who did most of the damage.
Wiltshire ended on 153-7 with Geoff Edwards scoring 38, Colin Webb 30 and a quickfire 24 off 18 deliveries by Mickey Dean.
In reply Hampshire cruised to the target in 33 overs, only losing two wickets, with John Harris undefeated on 61.
Wilts skipper Peter Hagelthorn said afterwards: "The great enthusiasm of the squad has not been rewarded by performances when, on occasions, we did not get the rub of the green.
"However we intend having one further match against Wiltshire Queries at Corsham on August 20.
"This will be open to players due to reach 50 next year so I would welcome anyone interested to make contact with us by calling 01722 712694."
