While hindered by foul trouble, the other starters, Kiwi Sam Mennenga and Mexican Karim López, tallied 16 and 15 points respectively.
Tai Webster, the freshly signed returnee from Europe, provided some valuable minutes for five points and a couple of rebounds, in a promising first showing since the 30-year-old Aucklander linked back up with the club earlier in the week.
Jackjumpers import guard Bryce Hamilton led the way for the Tasmanian side with 21 points. Their skipper Will Magnay scored 18 and there were also double-figure efforts from Josh Bannan (12), Majok Deng (11) and David Johnson (10).
The Breakers won the rebounding count 45-38 and shot the three-ball at a better clip – 34% (10/29) to Tasmania’s 27% (10/37).
The Breakers came out of the blocks like Usain Bolt and scored the first nine points of the game. A Mennenga two-handed slam made the highlight reel, which he soon repeated. Back in Breakers black for his first time since 2021, Webster scored with his first attempt, pushing the Breakers ahead 28-14 at the end of the first quarter.
The Jackjumpers started the second quarter with a stronger effort to trim the Breakers’ lead to two points midway through the period, before Baker made a trio of threes to give the hosts a 52-41 halftime lead. Less favourable for the hosts were the three fouls picked up by both Mennenga and López.
Ten straight points from Bannan kept Tasmania in the hunt, but the return of Mennenga and López from the bench brought some steel to the Breakers.
Hamilton peeled off a couple of long-range jump shots and with a quarter to play, the 2023 champions were within 10 points.
The fourth quarter opened as a tense, basket-for-basket affair until Jackson-Cartwright seized control. The lightning-quick guard snatched a steal and raced away for a transition lay-up, shattering the deadlock and blowing the lead out to a commanding 12 points with 5m 22s on the clock.
Hamilton tried to keep the visitors in touch, but Brockington slammed the door shut with a triple and a relentless put-back, pushing the Breakers out to a 93-80 advantage with three minutes to play.
Tasmanian Boomer Magnay trimmed the Breakers’ lead to single figures, but Jackson-Cartwright made the settling three and López added the icing with another long-range effort.
The Breakers now hit the road in Australia and won’t be sighted at home until January 4. Their tour of duty in Australia is a quartet of games beginning with South East Melbourne Phoenix on December 13. Visits to Cairns Taipans (December 19), Brisbane Bullets (December 22) and Tasmania (December 26) follow.
Fans will be excited to see them return to Spark Arena to host Perth Wildcats. With the recent move up the standings, fans will be there to back them drive for a playoffs spot.
