Lauren Winfield-Hill was left rueing an unlikely defeat for Northern Diamonds that took the shine off what was a brilliant individual performance from the wicketkeeper batter.
Winfield-Hall hit 110 off 126 balls to help take Diamonds to 280 all out in their opening day clash with Central Sparks.
But the formidable target proved to be not enough as Amy Jones hit a century of her own before some huge lower order hitting from Sarah Glenn took Sparks over the line with two wickets and 10 balls to spare.
"It's a bittersweet feeling, admitted Winfield-Hall. "It's nice to get my first ton at Emerald Headingley but it feels like we played 80 overs well and 20 overs poorly.
"It was difficult early on but I have worked hard on getting through those tough patches in one day cricket and make some big scores.
"I thought we had a really good score on the board at half time and we were confident but we just didn't back it up at the end and I think if we are being brutally honest we were complacent mixed with a lack of experience of being in that situation."
Despite the result, Winfield-Hall was overjoyed to see crowds back in the stands and welcomed the support they gave the Diamonds throughout a thrilling day's cricket.
"It was an exciting game to be a part of, but they're only good if you learn from the result," she added. "It was great to hear the fans again and we've had a beautiful day where the sun has come out for our first game.
"There are lots of positives to take and we know we've got to be a little bit better at the end of games. It's the first game and there's a lot of cricket this summer and now we have one day to get it out of our system and go again."
