The Tasmania JackJumpers' defence was just as leaky as their home stadium's roof as their eight-match winning run came to a crashing halt in a 105-91 loss to South East Melbourne.

Matt Hurt scored a team-high 20 points for the Phoenix and Joe Wieskamp (15 points), Jordan Hunter (17 points), Derrick Walton Jr (16 points) and Malique Lewis (14 points) made important contributions as the visitors cruised to victory on Sunday.

It was a 51st consecutive sellout at MyState Bank Arena in Hobart, but a leak in the roof stopped play for six minutes approaching half-time.

The JackJumpers trailed by just a point when that occurred, but the Phoenix dominated the contest from that point on to run out easy winners.

Jordon Crawford led the way for Tasmania with 16 points, while Reuben Te Rangi and Majok Deng scored 14 points apiece.

Tasmania had conceded an average of just 81.8 points per game across their eight-match winning run, but their defence was breached time and again by a hungry Phoenix outfit playing their third road game in the space of six days.

The result improved the Phoenix's record to 11-10, while the JackJumpers (11-9) are just one spot higher in fifth.

Phoenix centre Hunter scored 10 points in the opening term as the visitors took a 26-16 lead into the first break.

Star JackJumpers guard Crawford was held scoreless in the opening quarter but exploded with 13 points in the second as Tasmania briefly took the lead.

The leaky roof and subsequent water on the court caused a six-minute halt in play as staff piled towels onto the floor in a bid to get rid of the droplets.

A man with a bucket was eventually sent up to the roof to fix the problem, and when play resumed it was the Phoenix who came out firing on the way to taking a 56-49 lead into half-time.

Tasmania hit 10-of-20 from long range in the first half, with their hot shooting helping them back into the contest.

But it was one-way traffic in the second half, with the lead hitting the 20-point mark early in the final term as things got out of hand for Tasmania.
