In their 30-over match, the Wanganui U11's had a break through 23-run over the team in green, which coach Drew Morrison put down to them transferring what they learnt in midweek practice into the game situation.
After winning the toss, Wanganui put on 118-2, with Ben Loudon retiring on 30 while Angus Wallace finished unbeaten on 16, while Manawatu's bowlers conceded a significant number of wides among 52 extras overall.
Wanganui also gave away 46 runs but their bowlers and fielders still put the pressure on from the start of the innings, picking up wickets throughout before the home side was dismissed in the last over for 95.
Hunter Morrison with 2-1 off four overs was very economical, while Charlie Lourie (1-14 from five) and Shaun O'Leary (2-13 from four) also did well in a match were every player on both sides had a bowl.
Wanganui U15 were unable to replicate the younger team's success as they lost by five wickets in the damp conditions on their artificial wicket.
The visitors were in trouble at 60-6 with only Blair Pudney (17) surviving in the middle order, before he was joined by James Pennefather (52) to put on a 59-run partnership before they were all out in the 40th over for 148.
Manawatu had a couple of strong scorers in their top order who set up their victory by the 39th over.
Angus Dinwiddie (3-40 from nine) was the pick of the bowlers.
Wanganui were missing five players involved in a Collegiate 1st XI match, meaning they had to add new players to the lineup who did their best.
