Twenty20 Cup - North Division
Derbyshire 153-6 Innings Complete (S G Law 59) v Durham 154-4 (P Mustard 52, D A Warner 50)
Durham beat Derbyshire by 6 wkts
David Warner immediately demonstrated his potential to Durham fans by scoring a 29-ball half century as the Dynamos scored a six-wicket win in their Twenty20 Cup match against Derbyshire.
The 22-year-old Australian, Durham's new overseas signing, made 50 on his debut and Phil Mustard scored 52 as they chased down the home side's total of 153-6 in 18 overs.
Stuart Law top-scored with 59 for the Phantoms but the result, their fifth consecutive defeat, almost certainly puts paid to their quarter-finals chances.
With Derbyshire batting first, stand-in opener Graham Wagg made only nine for the home side before he was caught behind driving at Mitch Claydon in the second over.
Matters worsened when captain Chris Rogers went in the next over but the home side rallied after the setting sun held up play for half an hour.
Law added much-needed momentum by driving Ben Harmison for three consecutive fours and Greg Smith hit Claydon for six in an over that cost 15 runs.
Smith (22) fell lbw attempting a reverse-sweep but Law and Wavell Hinds continued in much the same fashion with another 50 in seven overs.
Hinds (23) cleared the ropes before being bowled by Gareth Breese and with John Sadler also falling by the wayside, Law was eventually run out for 59 in the 19th over.
With Durham facing a testing target, Warner hit Nantie Hayward's first ball to the fine-leg boundary before pulling Wagg for six and then driving him for two more fours.
He also hit four boundaries from Garry Park's opening over, partner Mustard content to adopt a more conservative approach until he drove Smith for six.
The pair had added 96 in 10 overs before Warner skied a pull at Wagg to midwicket.
Mustard then drove Mark Lawson straight for another six on his way to a 28-ball half-century before Derbyshire claimed Kyle Coetzer and Mustard in successive overs.
However, the damage had already been done and Ian Blackwell sealed victory with two overs to spare to keep Durham's hopes alive in the North Group.
