The Englishwoman, 19, shone in the sun over the Norfolk links to achieve a 4&3 success against Sweden’s Louise Rydqvist, 20, in the 36-hole Final.
Having defeated in-form duo Emilie Alba Paltrinieri and Hannah Darling yesterday, Baker continued her play to come out on top from a field of 144 players representing 24 countries this week.
Baker, who is member of Gosforth Park near Newcastle and attends the University of Central Florida in Orlando, became the fifth English winner of the coveted Championship in the last 13 years and celebrated with her dad, Steve, who caddied, and her mum, Louise. Having had to hole a 25-foot putt just to reach the match play stages, her triumph was even more noteworthy.
“It’s an amazing feeling, just incredible,” she said. “I can't believe it. I'm absolutely stunned but I'm just so happy. I worked really, really hard to get here and it's just such a satisfying feeling.
“Yesterday, in particular, was an absolutely dream day. I holed everything and hit it amazing. It all came together yesterday to give me this opportunity. So, yeah, it's been a long time coming and I'm just really proud of myself. I didn't do anything special today. I just got ahead and then kept the lead. It was about the person making the least mistakes today.”
By virtue of her victory, Baker earns dream places in the AIG Women’s Open, US Women’s Open, The Amundi Evian Championship and, by tradition, an invitation to the Augusta National Women's Amateur Championship.
She added, “Playing in the AIG Women’s Open is something I've really wanted to do for a long time and this means I don't have to pre-qualify which is great because that was the plan next week.
“And Augusta, oh, my gosh. That's not really come to my mind yet to be honest. But it will be an incredible experience, all just great opportunities for me.”
Baker, ranked 518th on the World Amateur Golf Ranking® (WAGR®), also joins an impressive list of past winners including LPGA victor Leona Maguire and major winners Georgia Hall, Catriona Matthew and Anna Nordqvist – last year's AIG Women's Open Champion at Carnoustie.
Coached by Andy Paisley at Hexham Golf Club – the brother of Tour player, Chris – Baker won the closing four holes in-a-row to lead three up at lunch after mistakes from Rydqvist, who is ranked 143rd on WAGR®.
It was a tight contest in the afternoon but after the lead was extended to five up through 28 holes, Rydqvist was unable to make a stirring comeback as Baker eclipsed her run to the quarter-finals last year.
It was a nervy start to the contest from both players in the blustery conditions and it was all square after ten holes, before Rydqvist’s birdie at the 13th took her ahead.
The Swede, though, struggled from the 15th and lost four holes on the bounce after wayward approach shots led to three straight bogeys and a double bogey at the 18th when she putted back off the green.
