Otago had its most successful day with a half and a win on the penultimate day of the Freyberg Masters (over-40) men's interprovincial on the Maraenui course yesterday.
Otago halved with Aorangi-South Canterbury in the morning and sneaked home with a 3 to 2 win over Tasman in the afternoon.
Waikato looks set to win the title this year, having won six from six, with matches against Taranaki and Auckland today.
In the morning Otago No 1 Andrew Hobbs turned three down to former Balmacewen golfer Jason Geary after the Aorangi No 1 eagled the eighth hole.
At No 2, Gary Creedy had his first loss of the tournament when Simon Wright birdied the 17th hole to take the match.
Stephen Hitchcox turned two up and coasted home in his match against Aorangi No 3 John Smitheram.
John McIntee had a narrow win on the final green over Peter Fox while Kyle Geary birdied the 17th to get back to square.
Geary and his opponent, the veteran Robbie Bell, had birdie putts on the final green which both slid past for a match and team half.
In the afternoon, Otago recorded its second win, beating Tasman by a narrow 3 to 2 margin.
Hobbs was in form and four under par when he beat John Murray with four holes to spare.
Creedy had lost his winning form yesterday and went down to Matt Bulfin, who turned the tables on the homeward nine with two birdies, while Creedy bogeyed 14, 15 and 16.
Both McIntee and Geary were one up playing the final hole but Lyall Marfell birdied the last to deprive McIntee of the win while Geary lost the last after encountering tree trouble.
This left Hitchcox at No 3 to go for the win. A shank on the 16th hole put him level with Wayne Robbins.
He scored a birdie on the 17th and a par on the 18th to snatch the crucial win.
Otago has a tough day today in the final round playing Canterbury this morning and Manawatu-Wanganui in the final round this afternoon.
