Logan (18) was reserve for the Otago men's team last year but made his full debut at No3 in the Toro interprovincial at New Plymouth earlier this month.
His best performances were in the Otago strokeplay, the Southland strokeplay and the North Otago 72-hole tournament. He accumulated 360 points in each event.
With the retirement of Brent McEwan, this year's event was one for the younger players, with Ryan Bellamy (St Clair) coming in second with 193.6 points.
A player's total points are divided by eight and they can play in more events and discard their worst scores.
Brandon Hodgson (Otago) was third, Sungwoo Han (Queenstown) fourth while the Bellamy family featured again with Ryan's younger brother Jacob coming in fifth with an average of 161.3 points.
Otago's No1 golfer and South Island champion Fraser Mac
Lachlan only competed in four events during the year but his tally was still divided by eight.
This placed him in sixth position narrowly ahead of Nick Borren (Otago), who also competed in four events.
Otago captain Chris Snow (St Clair) was eighth while Joseph Hancock (14) came in ninth with an average of 120 points.
The retired McEwan shared tenth place with Michael Ormandy (St Clair) on a 114.4 point average.
The top performers win financial prizes which are held by Golf Otago and can be used for golf equipment, tournaments and coaching.
