At the Utilita Bowl, Bouchier’s personal best trumped an exquisite 133 from Somerset’s Bex Odgers in Hampshire’s five-wicket win.
Odgers’ first professional ton tied with an unbroken 150 run partnership with Chole Skelton (77) – the highest seventh-wicket partnership in this country in women’s List A cricket and the fourth largest of all time for the seventh wicket in this format – had given Hampshire a tricky 282 to chase.
But Bouchier and international team-mate Freya Kemp hammered the bowling in a captivating 149-run partnership for the third wicket in front of England head coach Charlotte Edwards, as Hampshire strode to a fourth win in six.
Bouchier only fell when Somerset captain for the day, Niamh Holland pulled off a great catch at long on, but it did not stop Rhianna Southby, Naomi Dattani and Megan Sturge from ticking off the remaining 26 runs with more than nine overs to spare.
