Maia Bouchier and Ella McCaughan both struck unbeaten centuries as Hampshire thrashed Essex by 10 wickets in the Metro Bank One-Day Cup at Chelmsford.

Bouchier, overlooked by England for their T20 World Cup squad, dominated Essex for the second time in 10 days, following her 87 in the recent T20 clash between the teams with 136 not out.

She found a perfect partner in McCaughan, who reached three figures for the first time in her career as the pair shared an unbroken stand of 246 to reach the target, a record for any wicket in this competition.

It meant Liberty Heap‘s career-best 75 from 63 balls – a maiden List-A half-century – and 56 from Jo Gardner proved in vain, though their efforts did enable Essex to recover from the early damage wreaked by Hampshire spinners Bex Tyson (3 for 66) and Amanda-Jade Wellington (2 for 39).

After Jodi Grewcock chipped back to Tyson, Essex’s top order folded. Tyson trapped new signing Anneke Bosch lbw for a three-ball duck, while Wellington’s frugal first spell accounted for Ariana Dowse and Flo Miller, both while attempting to sweep. Grace Scrivens made 22, and when Georgia Adams plucked out Sophia Smale’s off stump, Essex were 112 for 6.

Heap, given a life on 27 when McCaughan dropped a chance at deep square, fought back by hitting Wellington back over her head for six. At the other end Gardner proved a great foil, hitting powerfully through mid-on and midwicket.

Gardner won the race to 50 before being trapped by Tyson, prompting Heap to accelerate further in hitting two huge sixes which threatened nearby houses and workers on scaffolding above the sightscreen.

Bouchier should have been back in the hutch for 17 early in the chase when hitting a full toss from Grewcock straight to the fielder in the deep only for it to be dropped over the ropes for six. The drop proved costly, as Bouchier showcased her undoubted class driving over the top and through the covers with her customary flourish and elegance.

She milked the spinners after passing 50, and hit another maximum before reaching her century off 99 balls. McCaughan was given a life on 74 when Miller shelled a chance at midwicket, but provided great support with elegant cover drives and a late cut for four off Smale.

The pair finish the match with a barrage of boundaries, McCaughan reaching her century just before victory was sealed with 70 balls to spare.
