New South Wales 275 for 3 (Patterson 125*, Philippe 58, Green 47*) beat Tasmania 274 (Wakim 76, Ward 47, Hadley 5-69, Sangha 3-57) by seven wickets

Kurtis Patterson's scintillating century and Ryan Hadley's five wickets powered New South Wales to a One-Day Cup final berth as they beat Tasmania by seven wickets with 19 overs to spare.

With a spot in the competition's finale on the line, NSW needed to chase down Tasmania's score of 274 within 40 overs to leapfrog Queensland into second spot.

And they were able to do so with ease, as Patterson's unbeaten 125 from 89 balls helped the Blues to a seven-wicket victory in 31 overs. The result meant NSW will face Tasmania again on March 11 in the final back in Hobart.

Playing as if it was a T20 match, Patterson whacked his third century across all formats for NSW this month, belting 17 fours and one six along the way.

Josh Philippe (58 runs off 29 balls) and Chris Green (47 runs from 45 balls) also played crucial supporting roles after Sam Konstas fell early to leave NSW 3 for 1.

Philippe and Patterson added 103 in just eight overs to put the chase well ahead of the rate.

Earlier, seamer Hadley pocketed 5 for 69, building off the six wickets he took against Tasmania in the Sheffield Shield midweek. The early part of the match had seen Mitchell Owen take to him with a flurry of boundaries to reach 35 off 12 before edging behind.

Legspinner Tanveer Sangha also claimed 3 for 457 as Tasmania were bowled out for 274 off the final ball of the 50th over.

Charlie Wakim had led the way for Tasmania with the bat with 76 from 73 balls, but consistent wicket losses meant the hosts were never able to build the momentum for an imposing first-innings total.
