White Rose top North Group
Yorkshire concluded their most successful Friends Life t20 North Group campaign by beating Derbyshire by 21 runs at Headingley Carnegie to top the table and earn a home quarter-final against Worcestershire.
It was their seventh win in 10 matches, the sequence being interrupted by two no-result fixtures, and their only defeat was inflicted by Durham who beat them by two runs in the opening game.
Yorkshire, put in to bat, were given the ideal start with an opening stand of 131 by Adam Lyth and Phil Jaques, a county record for the first wicket, and they never looked back, although the visitors worked hard to restrict them to 180 for five.
Lyth was the faster scorer of the two openers but both made good progress and helped himself to two boundaries in an over from Wes Durston which cost 18.
The pair put on 57 in the six-over powerplay and with Lyth reeling off a series of quality drives through extra-cover, he reached his fifty off 34 balls with seven fours and a maximum.
Tom Knight was pulled for six by Lyth and the stand raced into three figures in 11.5 overs before Jaques twice spooned Alex Hughes behind the stumps for fours and went to his half-century from 34 deliveries.
The stand went past the previous best for the first wicket of 116, set earlier this season by Andrew Gale and Jaques, but Lyth was caught on the midwicket boundary by Durston off Chesney Hughes for 78 from 51 deliveries, including nine fours and two sixes.
Jaques followed in the next over when Knight had him caught at cow corner off Alex Hughes for 64 from 47 deliveries, which included 10 fours, to leave Yorkshire on 150 for two in the 17th over and, although David Miller and Joe Root both weighed in with sixes, Rana Naved-ul-Hasan prevented a late flow of runs by picking up a couple of wickets.
Derbyshire did little early on in their innings to suggest that they could mount a realistic challenge, Usman Khawaja being caught behind by Gerard Brophy from Richard Pyrah's second ball in the third over and Durston having his leg-stump flattened by Mitchell Starc.
Chesney Hughes and Wayne Madsen brought about something of a revival with a 55-run stand in seven overs during which the latter drove Azeem Rafiq over long-on and hit his next ball for four.
Madsen was then caught and bowled by Rafiq for 21 and it became 77 for four as Hughes was run out when he could not beat Pyrah's return to the wicketkeeper.
Jonathan Clare and Alex Hughes fell in quick succession and it looked all over at 99 for six, but Rana had other ideas with 68 required from the last five overs. The Pakistani blasted Pyrah for three consecutive sixes off the first three deliveries of the 16th over and then ran three twos to give him 24 off the set of six.
He and Garry Park put on 55 in four overs for the seventh wicket before the latter was caught in the deep off Moin Ashraf, who bowled Tim Groenewald in the same over.
Chris Durham fell to Starc and Rana was denied the strike to continue his onslaught, ending unbeaten on 40 from 22 balls with four sixes as Derbyshire closed on 159 for nine.
