Launceston Church Grammar School's first XI started their State Association of Tasmanian Independent Schools (SATIS) cricket season impressively, winning their first two matches last week.
The undefeated side defeated Hutchins in a one-day match on Wednesday before proving way too strong for Northern counterparts St Patrick's College in the longer format on Friday and Saturday.
Dismissing South's Hutchins for just 136 thanks to strong performances from Edward Faulkner (3-28), Tom Beaumont (2-10) and Aidan O'Connor (2-17), Grammar limped to victory seven wickets down but still got the job done.
Will Bennett's 36 would be the top score, with the Greater Northern Raiders representative carrying his form into the two-day contest, taking 4-15 as they dismissed St Patrick's for just 49 in the first innings.

O'Connor then made 48 as LCGS tallied 152 before dismissing their rivals for 116, courtesy of some rear-guard action from Charlie Taylor (47).
Grammar would have to made just 14 to get their second win with James Leake removing Gilbert Loane.
Earlier in the week St Patrick's fell to Guilford Young College's star-studded line-up by 76 runs while Scotch Oakburn fell just short of defeating Hutchins, losing by three wickets after declaring at 7-288 with half-centuries to Oliver Gibson and Angus Foster.
