Test fast bowler Jhye Richardson has played a crucial role with the bat but suffered a hamstring injury while bowling in Western Australia's win over New South Wales in the men's domestic one-day cup final.

Shaun Marsh was also injured with a knee sprain in Friday's match at Melbourne's Junction Oval, as WA triumphed by 18 runs to claim its 15th men's one-day title.

The result saw WA avenge last year's defeat to NSW in the final.

In a see-sawing match highlighted by Hilton Cartwright's astonishing and crucial outfield catch, WA made 9-225 from its 50 overs before NSW was dismissed for 207 in 46.3 overs.

Richardson top-scored with 44, leading WA's rearguard fightback after it had slumped to 6-89.

An over after bowling Baxter Holt for a duck, Richardson pulled up awkwardly in his delivery stride and had to leave the field injured with NSW on 6-117.

Richardson took five wickets in the second Ashes Test win at Adelaide Oval in December, but then withdrew from Australia's squad because of soreness and was left out of the Pakistan tour squad.

Moises Henriques had paced the NSW innings with 43 from 75 balls when he belted spinner D'Arcy Short to long on.

Cartwright was horizontal when he took an all-time classic diving catch, leaving NSW 8-204.

It proved the match-winning moment, as Henriques and Ben Dwarshuis — who was unbeaten on 31 — had put on 36 for the eighth wicket when NSW appeared to be headed towards victory.

Adam Zampa and Tanveer Sangha were then dismissed for ducks to end the match.

Western Australian quick Andrew Tye took 4-30 and was named player of the match, while teammate Aaron Hardie snared 3-41.
