JETS broke their National Cup duck of recent seasons with a strong second half display against Brighton Bears on Sunday to book a place in the last eight in Coventry, writes Chris Beesley.
Fielding New Zealand shooting guard David Langrell for the first time, Chester pulled away from Nick Nurse's outfit after the break following a closely-fought opening period.
New boy Langrell, signed from Irish club Neptune, holds a UK passport because of his British mother and therefore does not count as an overseas player.
The sides were evenly matched in the opening exchanges and the scores were deadlocked at 17-17 at the end of the first quarter.
John McCord started brightly for the hosts with eight points in the period while both Albert White and Randy Duck showed their ability from downtown.
Jets introduced Langrell for his debut in the second period and he fitted in well to the team unit despite only arriving in Chester 48 hours earlier.
The highlight of the quarter was a Calvin Davis basket with two seconds remaining on the clock, after Jets had worked an opening with a string of patient passes.
Jets had edged 37-36 ahead by the break and the third quarter was a three-point duel with Brighton's White, Duck and Mike Brown also sinking outside shots.
But John Thomas also hit a big three and man of the moment was Pero Cameron who nailed a nine-point hat-trick to help Jets lead 67-59 going into the final quarter.
Jets continued to score from all areas in the latter stages and eventually completed their victory by a comfortable 16-point margin.
Coach Robbie Peers said: 'That was our best performance of the year. We had execution at both ends of the floor and made some good decisions. Our outside shooting was good which also covers cracks.'
Jets' scorers: McCord (22); Thomas (18); Davis (17); Hamilton & Cameron (both 14); Langrell (5).
