Amy Hunter celebrated her 16th birthday in style by scoring a record breaking century as Ireland Women beat Zimbabwe by 85 runs to clinch a 3-1 series win.

The Instonians teenager overcame previous record holder - India's Mithali Raj, who was 16 years and 205 days when she reached the landmark back in 1999.

Shahid Afridi is the youngest man to achieve the feat, at 16 years and 217 days.

Her 121 not out was also an Irish ODI record - beating Karen Young's 120.

Hunter's efforts together with half centuries from Gaby Lewis (78) and skipper Laura Delany (68) saw Ireland pile on the runs - their total of 312 for 3 another Irish record.

She shared stands of 140 for the second wicket with Lewis, and went on to better it with a third wicket partnership of 143 with Delany,

Zimbabwe managed a respectable 227 for 8 in their chase, but the result was never in any doubt.

Josephine Nkomo top scored with 66, while for the Irish there were two wickets apiece for Laura Delany (2-32) and Sophie MacMahon (2-44). "

When I got to my hundred, I had no ideal what to do," said Hunter afterwards.

"I didn't know whether to take the helmet off or keep it on. It was unbelievable."

Ireland Women will be back in Zimbabwe next month for the World Cup qualifiers with the top three gaining slots, while the top five will go forward to the ODI League Championship.
