Hawkes Bay spinner Angus Schaw followed Patel's lead by cleaning out Wanganui's middle order in the second innings for his five-wicket bag.
For coach Dominic Rayner there was not even scant consolation from any player's performance it has been the worst representative season that he has been involved in since 1999.
"We just didn't bowl good enough at the end of the day. They had spinners that turned we didn't.
"Maybe we're just not good enough."
Rayner said the quality of play had slipped so far on the local scene that there had to be changes or Wanganui teams would continue to be exposed.
"I don't know what the answer is, I'll let the board sort that out.
"A winter camp would be very beneficial but our basic skills at Wanganui club cricket in batting, bowling, just aren't good enough any more.
"It needs someone willing to do [senior development] and put that time into it, it should be Dilan [Raj]."
Development officer Raj said players could always come to him to do extra work in the off-season.
However, he felt the bigger issue was attitude towards preparation senior players were "well-versed" in what their abilities were, but they had to knuckle down and do the "hard yards" if they wanted to play at a level expected at Hawke Cup.
Wanganui actually made a decent start on Saturday morning as Paul O'Callaghan picked up Matt Edmondson with a sharp caught and bowled.
Having the visitors five wickets down at the lunch break would normally seem like a decent morning session, but not when 213 runs were on the board.
Century-maker Seb Langridge picked up where his father left off the last time Hawke Cup was played at Centennial Park, scoring 132 from 115 balls.
O'Callahgan and Sam O'Leary broke the key partnerships to give Wanganui a sniff, but Jarrod Smith, son of former wicketkeeping great and SKY commentator Ian, was beginning to get his eye in.
Smith and fellow century maker Scott Schaw scored all round the park, alternating from quick singles early in the innings to strike 27 boundaries and five sixes between them while putting together a 187-run partnership, as O'Leary, Mark Fraser and the Kinnerlys Fraser and Ross all took punishment.
Grant brought himself on and while hit around he did pick up both key wickets but by now Hawkes Bay were looking for big shots.
Wanganui had already lost their top order and were seven down early on Sunday afternoon, and the procession never stopped. Fraser fell to Patel twice for the dreaded pair, while Grant tried a rear guard action in the second innings but was Angus Schaw's fifth wicket when in sight of his first 50 for Wanganui.
