University-Grange will have some soul-searching to do following a colossal 235-run loss to Green Island at Tonga Park on Saturday.
But had it not been for an astonishing innings from Gregor Croudis, the game might have been much closer.
Croudis whacked 12 sixes and 11 fours on his way to 156 from 96 balls. Opener Joel Meade made 68 from 98 in a supporting role to help his side post 310.
Otago Boys' High School pupil Jacob Cumming did his part with the ball for University-Grange. The promising all-rounder took three for 60 from 8.3 overs. He is the son of former test and Otago cricketer Craig Cumming.
He missed out with the bat but so did just about everyone else in his side.
University-Grange was rolled for just 75. Veteran spinner Mark Joyce took four for six from 10 miserly overs, and leg-spinner Jack Mockford nabbed two for 26.
Kaikorai 157 lost to Taieri 158 for four
Taieri maintained its unbeaten record in the one-day tournament with a six-wicket win against Kaikorai at Brooklands.
All-rounder Harsh Visavadiya ripped through the middle order to help dismiss Kaikorai for a modest 157.
The leg-spinner claimed four for 16 from nine overs. Fellow spinner Ben Lockrose took two for 24 and seamer Marcus James two for 15 up front.
Opener Rhys Bayly saved his side's blushes with a gutsy 68, and Matt Hunter (24) and Jeremy Smith (23) made cameos.
Smith was the pick of the Kaikorai bowlers with one for 29.
Beckham Wheeler-Greenall (38) and Jake Foley (37) combined in a 59-run stand for the third wicket to all but seal the win. Jarryd Taig completed the job with an undefeated 26.
North East Valley 246 for nine beat Carisbrook-Dunedin 63
Fringe Otago seamer Travis Muller returned to form with a five-wicket bag to guide North East Valley to a chunky 183-run win against Carisbrook-Dunedin at Tonga Park.
Muller, who played in Otago's opening Plunket Shield match this season, took five for 20 to help dismiss Carisbrook-Dunedin for a paltry 63.
The right-armer picked up the key wicket of Volts opener Camden Hawkins for 18 and also accounted for Anjas Bhogal for 15.
With those two removed, the innings folded quickly. Patrick Arnold was the only other player to notch double figures for the home side.
Earlier, Muller had cracked 48 from 57 balls to help his side reach 246 for nine.
Will Kindley top-scored with 61 and Llew Johnson made a useful contribution of 33.
Arnold was the pick of the bowlers for Carisbrook-Dunedin with three for 37.
