The Sydney Sixers maintained their dominance over the Brisbane Heat by securing a narrow four-run victory on Thursday in the Big Bash League.
Reigning champions Heat remain without a win against the Sixers in the competition and they desperately wanted a success to get their faltering campaign back on track.
The home side needed five off the last ball in order to claim a dramatic victory, but Ben Cutting could only find Moises Henriques near the boundary rope while attempting the match-winning shot.
After losing the toss the Sixers were put in to bat and they posted 140-8 from their 20 overs, although at the time it did not appear to look a match-winning total.
Michael Lumb was the pick of their batsmen with 56 from 42 with only Henriques, Marcus North and Ravi Bopara subsequently reaching double figures.
Opener Nic Maddinson fell in the second over for nine, although the pairing of South Africa-born Lumb and Henriques (19) managed to steady the ship.
The enterprising Lumb eventually perished for 56 from the bowling of Ben Cutting after riding his luck somewhat throughout the innings.
North managed 13 runs, but his strike rate was less than a run a ball and while Bopara did manage a six he was caught behind by Craig Kieswetter off Cameron Gannon, who finished with figures of 4-24.
Jordan Silk, Daniel Smith and Brett Lee all came and went without making an impact as a lack of boundaries at the back end of the innings hurt the Sixers.
The Heat only needed seven runs and over to claim their second win of the season, but they were unable to score quickly with Luke Pomersbach scoring 15 from 15 before departing.
Joe Burns (1) and Daniel Christian (1) followed quickly, although Craig Kieswetter was able to keep the scoreboard ticking over.
Chris Lynn accelerated things with a quick-fire 34 from just 21 deliveries before being bowled by veteran fast bowler Brett Lee.
Kieswetter departed on 38, but only from a spectacular one-handed catch by Silk. His exit looked to curtail their hopes, although the home side were not done yet.
Chris Sabburg added a credible 19 from 19, but it fell to Cutting to win the match. He smashed a six from the penultimate ball, but was unable to replicate the feat from the final delivery meaning a win for the Sixers.
