His outfit posted 148-9 in 29.4 overs.
Conwell junior made 39 from 31 at No.1, against a Poverty Bay pace attack that bowled well. Cody McMurray took 2-5 in three overs, with one maiden, Max Egan 2-19 in three overs and spearhead Reuben Walsh 2-19 in 3.3 overs.
Captain and opening batsman Jack Roberts (18 from 31, four boundaries) was the leading run-scorer in the chase. The Bay's biggest partnership was 22 between Roberts and Hunter Irwin (11) for the second wicket.
Poverty Bay were al1 out for 103 in 28.3 overs. Ninth man in Hugo Phillips bustled his way to 15 against a quality Wairarapa attack that included off-spinner Reuben Conwell (2-1 off two overs), Ben Gardiner (2-2 off, 2.2 overs) and Year 6 tearaway Angus McArthur (2-15 off 3).
In Game 2, Poverty Bay achieved victory against Porirua with 7.4 overs in hand but only two wickets standing.
Roberts won the toss, chose to bowl on the Park Island grass pitch and dismissed the Wellingtonians for 138 in 25 overs.
Xander Last, batting at No.5, hit two sixes, and 12 fours in a remarkable innings of 74 off 62 balls.
Opening batsman Caleb Bloomfield 10 off nine balls was Porirua's next-best effort against gloveman-come-leg-spinner Arthur Cave (2-2 off 2), Cody McMurray (2-12 off 3) and seven other bowlers who took one wicket each.
First-drop Hunter Irwin (25) and Jed Reynolds (24), the sixth man to bat, were in imperious form for the Strikers.
Captain Roberts (6) and Irwin put on 34 for the second wicket. The Reynolds-Cave (12) seventh wicket-partnership was worth 22 runs.
Poverty Bay No.11 Cole Hogarth (1no) took the last run off Tristan Jeyathas's second ball of the 22nd over for 139-9.
Game 3 against Dannevirke on Park Island 3 was abandoned because of rain and Central Hawke's Bay Gold beat Poverty Bay by five wickets at the boutique Clifton County Cricket Ground on the Tuesday morning.
Gold opted to bowl first. Poverty Bay openers Roberts (35) and McMurray (24) put on 74 in 18.2 overs, a tremendous stand.
Hugo Phillips (12), at No.4, was the only other batsman to score in double figures as the Strikers made 111-10 in 30 overs.
CHB’s Noah Waite snared 2-5 from four overs and was pivotal in restricting the Bay to a modest total.
No.8 Henry Mullany then made an unbeaten 43 off 27 balls without hitting a single boundary.
He and Flynn O'Brien (17), who batted at six, saw the side home, Mullany hitting Cole Hogarth for four off the last ball of the 19th over, with CHB six wickets down for 114 and the win.
The Poverty Bay Strikers' last game, a 65-run towelling of Johnsonville on Frimley Park, was a grand way for them to sign off.
Johnsonville won the toss, bowled and the Bay amassed 188 all out in 28.3 overs.
First-drop Arthur Cave (37), Hunter Irwin (29 at No.5) and Roberts (23no as the 12th man to go in) excelled.
Cave and Irwin put on 55 for the fourth wicket. Irwin and Ged Cook (8) made 34 for the fifth wicket, advancing the score to 130-5.
Hogarth (8 at No.6) and Roberts' last-wicket stand produced 30, a wonderful effort.
Mitchell Collier (2-7, 2, overs), Charlie Dermer (2-12, 3 overs), Ryan Morgan (2-19, 3 overs) and Stella Richards (2-23, 3 overs) were resilient and resourceful with the ball for Johnsonville.
The Wellington side were bowled out for 123 in 27.3 overs. Luca Anderton (25), at No.8, was their highest individual scorer.
Three other batsmen made minor starts, but Reuben Walsh (3-9 in 2.3 overs), Charlie Butt (2-18, 3 overs) and their supporting cast were good enough to see Poverty Bay comfortably home.
Poverty Bay Strikers captain Jack Roberts, 12, said: "Our fielding improved a lot during the week and it was always fun with my boys, and even more fun organising them."
