Durham put in a superb display to beat Yorkshire and secure a place in the Royal London One-Day Cup semi-finals.
A resolute all-round performance from Paul Collingwood and a century from skipper Mark Stoneman were the outstanding features of the 31 run victory at Headingley.
The former England all-rounder was second top-scorer with 38 in Durham's 237 and he then weighed in with two for 29 off his ten overs as Yorkshire were bowled out for 206 with 11 balls remaining.
Yorkshire appeared well on course to reach their target after openers Adam Lyth and Alex Lees hit 58 off the first ten overs but John Hastings changed the picture with two wickets in two balls, Lyth edging a wild drive to Mustard and Kiwi Kane Williamson failing to remove his bat in time and giving another catch to the wicket-keeper.
Gary Ballance, released from the England squad for the match, survived a return catch to Hastings before he had scored - one of several chances to go begging - but he helped to repair some of the damage in a 75 stand with Lees which ended when Lees smacked Rushworth to Stoneman at cover.
Jonny Bairstow fell second ball, caught by Mustard standing up to the stumps, and although Ballance continued to hold firm no-one was able to stay with him for any length of time.
Ballance was eventually eighth out for 61 from 89 balls with three boundaries, caught by Paul Coughlin aiming a pull at Scott Borthwick, and although Richard Pyrah flung the bat for an unbeaten 29, Yorkshire never got really close to winning the game.
Put in to bat, Durham made excellent progress at the start and Stoneman went on to stroke a chanceless 102 off 120 balls with ten fours and a six.
But the captain's departure in the 40th over sparked a collapse which saw the last seven wickets topple in nine overs for the addition of 59 runs.
Yorkshire had to rely heavily on their back-up bowlers, the new-ball pairing of Tim Bresnan and Jack Brooks conceding 97 runs between them off 18 overs while picking up one wicket.
Pyrah finished with four for 51 and Steven Patterson three for 39 but the most economical was leg-spinner, Adil Rashid, who gave away only 37 runs from his ten overs and picked up two of the first three wickets to fall.
The innings was only three overs old when umpires Nigel Cowley and Martin Bodenham led the players off the field for half-an-hour in order to allow paramedics to screen off and attend to a male spectator who had collapsed in the Trueman enclosure at the pavilion end.
Upon the resumption, Stoneman and Mustard got Durham moving with a spate of boundaries with both Bresnan and Brooks suffering and when Pyrah took over from Bresnan his third ball was pulled over mid-wicket for six by Stoneman.
The scoring was slowed down by Rashid and Patterson and the breakthrough came at 57 in the 15th over, Mustard bobbing up a catch to wicketkeeper, Bairstow, as he attempted a reverse sweep, the batsman having made 23 from 37 balls with four boundaries.
Calum MacLeod was bowled driving at Patterson and Borthwick was caught by Bresnan at mid-on coming down the pitch to Rashid to leave Durham on 98 for three at the half-way stage of their innings.
They were revived by a stand of 80 in 15 overs between Stoneman and Collingwood, the opener punishing Brooks with three boundaries off four balls and Collingwood driving Pyrah high over the rope at long-on.
Collingwood cheekily reverse glanced consecutive balls from Patterson for fours before Stoneman pinched a single against Rashid to complete his century off 117 balls with ten fours and a six.
Then Stoneman pulled Pyrah to Ballance running in from the square leg boundary and in the next over from Brooks the England man took a similar catch to get rid of Collingwood for 38 off 44 balls with five fours and a six.
It became three wickets for six runs off 13 deliveries as Keaton Jennings patted back a simple catch to Pyrah and with their tails up Yorkshire's attack stayed very much in charge.
Breese skied Patterson to Bresnan at mid-on, Gordon Muchall holed out to Williamson at long-on off against Pyrah and Patterson bowled Hastings with a low full toss, leaving Pyrah to round things off by skittling Rushworth.
Stoneman said of Durham's win: "This was my first century as captain in English one-day cricket and it was very pleasing although I was disappointed still not to be there at the end of the innings. If I had been we could have been looking at 265-270 but we knew that if we were able to apply pressure and take wickets we could defend 237.
"From a personal point of view it was nice to score runs when it matters and the lads have stepped up every time in the competition."
