Hall to the fore but Northants fall flat
Captain Andrew Hall's four wickets were in vain as Northamptonshire slumped to a 12-run defeat to Yorkshire in the Friends Life t20 at Wantage Road.
Yorkshire collapsed from 87 for one to 144 all out from 20 overs with Hall taking 4-23 and Joe Sayers top-scoring for the visitors with 44 off 34 balls.
But an awful start to the Steelbacks' reply ensured they fell short of their target despite Alex Wakely's 38 off 33 deliveries, and they remain bottom of the North Group with one win from 10 games.
Asked to bat first, Yorkshire lost skipper Andrew Gale for seven when he chipped Luke Evans to Lee Daggett at mid-on.
Adam Lyth, who smashed 30 off 18 balls, clubbed Hall to James Middlebrook at mid-off in the 11th over to break a second-wicket stand of 71 with Sayers, who departed in the next over when he edged Daggett behind.
Jonathan Bairstow had his off and middle stumps taken out by Hall before Joe Root launched Johan Botha to Wakely at long-on.
England paceman Ajmal Shahzad had hammered 12 off five balls when he his middle stump was uprooted by off-spinner Middlebrook, and Hall struck twice in as many balls when he had Gary Ballance caught behind and trapped Richard Pyrah lbw.
Adil Rashid walked on five when he nudged Daggett to wicketkeeper Niall O'Brien before Ryan Sidebottom was run out by Wakely from long-off off the final delivery of the innings.
Chasing 145, Northants took nine balls to get off the mark and lost Bilal Shafayat for a duck in the second over when he was pinned lbw by Shahzad.
O'Brien made just a single before drilling Sidebottom straight to Azeem Rafiq at mid-off.
Rob White, whose innings of 12 spanned 19 balls, was lbw to Pyrah to leave Northants 27 for three, but Wakely hung around before holing out to Ballance at mid-off off the same bowler.
Botha was run out for 11 when Sidebottom touched Rob Newton's straight drive on to the stumps in his follow-through before the same man trapped Newton lbw for 37 two balls later.
Hall was bowled for 10 by Shahzad in the penultimate over, and Middlebrook and Jack Brooks could not recover the situation.
