Yorkshire concluded their most successful Friends Life t20 campaign by beating Derbyshire by 21 runs at Headingley to top the North Group and earn a home tie in the quarter-finals.
It was their seventh win of the campaign, 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 match.
Put in to bat by Derbyshire, Yorkshire had 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, their joint highest score of the season.
Derbyshire looked beaten at 99 for six but Rana Naved had other ideas with 68 wanted from the last five overs.
He blasted Pyrah for three consecutive sixes off the first three balls of the 16th over and then ran three twos to give him 24 off the over.
He and Garry Park put on 55 in four overs for the seventh wicket before Park was caught in the deep off Moin Ashraf who bowled Tim Groenewald in the same over.
Chris Durham fell to Starc and Naved was denied sufficient of the strike to continue his onslaught, ending unbeaten on 40 from 22 balls with four sixes, Derbyshire closing on 159 for nine.
Yorkshire now play Worcestershire at Headingley in the quarter-finals on either July 24 or 25.
England are eying a 4-0 NatWest Series victory over Australia, but admit they may yet consider resting first-choice players for the final match at Old Trafford.
Alastair Cook spoke, after his team’s eight-wicket win at Chester-le-Street had on Sunday established an unassailable 3-0 lead, of the cachet of a clean sweep against the old enemy. He said: “There is always a chance that we will rotate.
“We want to win 4-0 but we will look at selection, like we always do.”
