Yorkshire 191 for 5 (Lyth 58*) beat Unicorns 189 for 9 (Pyrah 3-34) by five wickets
Adam Lyth's unbeaten half-century carried Yorkshire to a five-wicket win over the Unicorns in a close Yorkshire Bank 40 match at Chesterfield.
Rich Pyrah took 3 for 34 as Yorkshire restricted their hosts to 189 for 9, Aneurin Norman top-scoring with a rapid 38 not out from No. 9. But Yorkshire then slipped to 24 for 2 and 88 for 4 and looked to be progressing too slowly, until Lyth produced a late barrage of boundaries to take them to their target with seven balls to spare.
The Unicorns chose to bat after winning the toss, but lost openers Tom New and Tom Lancefield to Steven Patterson in the seventh over to leave them 22 for 2. Michael O'Shea made 26 and put on 42 with Garry Park before both were dismissed in the same Pyrah over, and another pair of wickets fell on 103 as Adil Rashid removed Scott Elstone and Vishal Tripathi in successive balls.
Captain Keith Parsons made 28 before being run out by Lyth, and Glenn Querl scored 23 at close to a run a ball but was then bowled by Ryan Sidebottom. But it was Norman who lifted his side to a competitive total, smashing four fours and a six in a 26-ball effort.
Warren Lee removed Pyrah and Andrew Gale in successive overs before Yorkshire rebuilt with a stand of 56 between Phil Jacques and Gary Ballance. The pattern of the day, with wickets falling in pairs, continued as Norman had Jaques caught by Parsons and Ballance, six short of a half-century, was bowled by Luke Beaven.
Lyth found an ally in the in-form Rashid, who contributed 32 to a stand of 55 before becoming Beaven's second victim. Lyth had scored the more slowly of the pair and was also outpaced by Andrew Hodd's run-a-ball scoring rate in the early part of their sixth-wicket alliance.
But having made only 24 from his first 46 deliveries, Lyth then cracked 34 from his next 14 - with five fours and two sixes - to secure Yorkshire's first victory in the competition.
