However the Pennefather's – James and father Martin – both took 2-24 from their four overs to make sure none of the top order could anchor the end of the run chase, and then Gerard Hobbs got into the lower order for another big T20 haul – taking 4-12 in three overs.
After Quinn Mailman (17) no-one else could get out of single figures, including regular batsmen like Bevan Hunter and Dominic Lock, the latter stranded after taking a single off his only delivery, as Tech couldn't get going in the final over and finished 140-9.
In the other game at Victoria Park, Matt Burke Engineering Marton Saracens picked up their first victory in any format in months with a win over Marist.
One of the key factors was the welcome return of representative allrounder Craig Clare, who took the first half of the summer off to heal up and get refreshed from a long and successful rugby season.
