Nathan Lyon has gotten some confidence ahead of the first Test with a record-breaking haul of 4-10 to help NSW to a six-wicket win over Queensland in the domestic one-day cup final at North Sydney Oval.

Lyon, who will be key to Australia’s hopes of victory in their three-Test series against South Africa that starts on November 3, made a mockery of the ground’s reputation for monster totals.

Lyon claimed the key scalp of Usman Khawaja as Queensland collapsed to 7-108 in the 31st over and were bowled out for 186 after 46.5 overs.

NSW slipped to 3-19 in response but Moises Henriques steadied with a captain’s knock of 85. The hosts hauled in their target with 41 balls remaining.

It is NSW’s 11th one-day title overall and the first time they have gone back to back in any competition since lifting the one-day cup in 2002-03.

Lyon claimed 3-3 from his first four overs and didn’t concede a single boundary in his 10 overs, which set all sort of records and earned him man-of-the-match honours.

The stellar performance represented the offspinner’s best figures at any level in a one-day game, while it set a new mark for the most economical 10-over figures by a NSW bowler in a domestic one-day clash.

It was a timely return from Lyon, who was dropped by NSW for last Friday’s elimination final after claiming only four wickets during the pool stage of the tournament.

“For Australia this is a real positive sign. Nathan Lyon’s getting some confidence .. in a big game like a final as well,” former skipper Michael Clarke observed in the Nine Network commentary box.

Joe Burns, who like Khawaja is hoping for a Test recall when the squad is announced on Friday, was run out for 18, igniting a collapse of 4-23.

Khawaja, who top-scored with 35, loomed as the batsman most likely to ruin NSW’s hopes of back-to-back cup titles.

Asked to bat first by Henriques, the Queensland skipper struck six boundaries before coming unstuck against spin.

The left-hander’s attempted sweep resulted in a skied edge that wicketkeeper Peter Nevill gleefully accepted.

Lyon also had Marnus Labuschagne caught in the deep, while he removed Jason Floros for a duck and Ben Cutting for eight.

Henriques was forced to dig in after Bulls paceman Michael Neser fired out openers Ed Cowan and Larkin plus Nic Maddinson.
