Yorkshire, playing their second game at tier one level following a narrow defeat by Somerset at the weekend, lost two early wickets at The Oval after being put in by 2025 semi-finalists Surrey.
Winfield-Hill hit eight eight fours in a well-played 60 off 70 balls, adding 74 with Sterre Kalis (38), but both fell to Maitlan Brown in the space of three balls and from 132-2, the innings went into sharp decline.
Winfield-Hill was given out caught behind even though the ball appeared to hit her helmet – and a five-run penalty was imposed for her reluctance to leave the crease.
“It changed the game completely. It wasn’t out, and then the management around it was pretty poor and knocked us back. It definitely affected us and I’ve spoken about the emotional control we are probably lacking in key moments,” coach Richard Pyrah said afterwards.
They were all out for 185 at the start of the 41st over, losing their last four for no runs, and after rain left Surrey with a revised target of 193 from 44 overs, they were in a hurry from the start as Scholfield hit two sixes and 17 fours.
The home side also suffered a collapse with six wickets going down for 35 runs, but Alice Davidson-Richards kept her head and stroked Beth Langston to the cover boundary in the 24th over to finish 35 not out and see them home by three wickets on 193-7.
