Alyssa Healy set a world record for the largest score in women’s Twenty20 cricket as Australia posted a mammoth 2-226 in the third and final match of the series against Sri Lanka at North Sydney Oval.

Healy batted through the innings to end unbeaten on 148 off just 61 balls. The opener reached the world record with a six in the penultimate over, eclipsing teammate Meg Lanning’s previous mark of 133 set against England only two months ago.

Having celebrated her 100th T20 international two days ago, Healy comfortably passed her previous personal best of 90.

Opener Healy was at her free-flowing best on Wednesday as she scored the fastest T20 half-century by an Australian, and the second quickest ton in women’s international T20 matches.

Alyssa Healy smacks an unbeaten 148 to lead Australia to 2-226 in the third and final T20I against Sri Lanka

Australia are batting first in the third and final T20 International against Sri Lanka at North Sydney Oval.

Captain Meg Lanning did the honours at the toss - having called on wicketkeeper Alyssa Healy as a specialist coin flipper in the opening two matches - and was successful, electing to set the tourists a target as her team eyes a series sweep.

Australia go in unchanged from the second T20I, while Sri Lanka have made two changes as they seek their first ever win over their No.1 ranked rivals.
