Yorkshire 165 for 5 (Jonassen 65; Arlott 2-27, M Taylor 2-29) beat Warwickshire 161 for 3 (Freeborn 65, Redmayne 52) by five wickets
A century partnership between Jess Jonassen and Lauren Winfield-Hill sealed a second Vitality Blast win in three days for Yorkshire as they emerged victorious over Warwickshire Bears by five wickets at Edgbaston.
With Yorkshire 14 for 2 and chasing 162, Jonassen (65 from 40 balls) and Winfield-Hill (42 from 35 balls) took the game away from the Bears, who had posted a competitive target thanks to contributions from Abigail Freeborn (65 from 49 balls) and Georgia Redmayne (52 not out from 36 balls).
Freeborn and Nat Wraith (24 from 21 balls) quickly introduced impetus to the Bears' innings, before the latter was stumped off the bowling of Jonassen.
Freeborn, dropped on two by Sarah Glenn, and Redmayne then established a platform on which they could accelerate the Warwickshire total; opener Freeborn brought up her fourth half-century of the Blast in 40 balls when she cut behind square.
The Warwickshire pair continued to score at a rate - at one stage in the middle overs, they played 28 consecutive scoring shots, routinely turning over the strike and applying pressure to the Yorkshire bowling unit.
Having been 66 for 2 at the halfway stage in their overs, the Bears continued to lift the run-rate, demonstrated by one of the shots of the day when Redmayne handsomely lifted Glenn to deep mid-wicket boundary.
The momentum was threatened when Freeborn nicked off, swinging at a wide delivery from Jessica Woolston that found the safe gloves of Winfield-Hill to bring to an end a 72-run partnership.
Redmayne, assisted in the closing stages by Em Arlott (15 from 9 balls), ensured that Warwickshire continued to score fluently, however, and with the final two overs costing Yorkshire 23 runs, the Bears managed to set their visitors 162 for victory.
Yorkshire looked to be in trouble in the early stages of the powerplay when Arlott struck twice in her first over.
Erin Thomas deflected a delivery straight up in the air for keeper Wraith and then fellow opener Ami Campbell, visibly furious with herself, slapped another ball straight to Warwickshire captain Georgia Davis at mid-on.
That brought Winfield-Hill, who scored 99 in the win over Somerset on Friday, to the crease; she and Jonassen quickly reversed the pendulum of momentum and the latter, in particular, began to assert.
Australian Jonassen brought up her half-century from 32 deliveries with a straight six back over the head of bowler Hannah Baker before, in the same over, she sent another delivery towards Davis at mid-off that the Bears captain failed to hold onto.
By the time Millie Taylor had Jonassen stumped when short of her ground, she and Winfield-Hill had put on 104 for the third wicket and Yorkshire required almost a run a ball for victory.
Amu Surenkumar snared a leading edge from Sterre Kalis and then Millie Taylor claimed the key wicket of Winfield-Hill, who reverse swept straight to Redmayne at point, to cause late tension.
Glenn (21 from 11 balls) and Alice Clarke (15 from 18 balls), though, then saw the visitors home.
