Colin Munro has been in fine form for Auckland in the 50 over Ford Trophy competition in his native New Zealand.
The 27-year-old, who was Worcestershire's NatWest T20 Blast overseas player in 2014, is averaging 83.33 with the bat after six matches.
Munro has scored three half centuries and his latest knock steered Auckland to a four wicket away win over Wellington with 10.5 overs to spare.
Wellington opted to bat after winning the toss and reached 208-7 in their 50 overs.
Munro came in at 77-2 in the 17th over but batting at number five after Rob Nicol was forced to retire injured.
It was a stand of 90 in 15 overs between Munro and Craig Cachopa (44) which was the decisive one of the match.
There was a little wobble as three wickets fell for four runs but Munro remained at the helm and finished unbeaten on 65 from 63 deliveries with one six and eight fours.
His scores in the competition are 79 not out, 12 not out, 22, 22, 50 and 65 not out – a total of 250 runs.
Munro finished as Worcestershire's second highest run scorer in the T20 Blast behind skipper Daryl Mitchell.
