The 18-year-old retired 59 not out after the mandatory 25-ball walk-off at University Oval to set up a nine-wicket victory against Trevallyn.

The knock had happened to be Norton-Smith's second highest score this campaign, a fifth half-century and also a seventh time she had retired.

The Tigers gun opener has been dismissed three times, leading the runscorers with 329 over the season at 109.6.

Trevallyn initially looked to have scored a competitive 3-122 in its first grand final.

The reigning premier had restricted the rookies to 2-42 in opening 10 overs after a wicketless Norton-Smith earlier conceded just the five runs off her four overs.

But Maxine Woods fought back in the second half of the innings with 38 and Tracey Miller also added 26, upping the ante until the pair were had been forced to retire.
