Both teams knew they would have to push the envelope to get a result out of the match last Saturday after the first week was washed out.
The Mariners won the toss and batted first as Josh Smith, moving up to number three, made a crisp 31 to signal intent.
Captain-coach Brendon Diamanti took his season tally to 278 runs in a top score of 61, the third time he has passed 50 this season.
Jayden Derosa occupied the crease with a sound 41 and Tony Coulson returned to form with a brisk 36no in the Mariners’ 5-188 from 57 overs.
University had the best part of 40 overs to make a game of it, but Rockingham-Mandurah’s bowlers tied them in knots early.
The chief wrecker was Joel Marion in the most impressive display of his burgeoning first grade career.
Marion took 3-30 from 12 overs and fellow young gun Jacob Rodgers took 2-40 in an overall encouraging display for the Mariners, despite the students holding on at 6-134.
Fourth grade broke their duck in style with a slashing outright result at UWA Sports Park.
The Mariners’ 8-204 was more than enough as they took a buzz-saw to the students’ batting for lowly numbers of 80 and 53. The first innings ended after paceman Guy Lewis, leg spinner Steven Cairns and Ryan Hoskins snaffled three victims apiece.
Just 27 overs later, the game was complete as Cameron Harvey wanted in on the fun and ended up with 6-31 after playing a set-up role earlier in the day.
The women’s B grade side went out with a bang to defeat South Perth in their last match of the Twenty20 season at Careeba Reserve on Sunday.
