Higgins fourth as closing 67 seals Derksen’s victory
Derksen carded six birdies, including a decisive one from 15ft on the 18th, for a 13-under-par total of 275 at Santo da Serra.
Scotland’s Gary Orr had a chance to force a play-off with a birdie on the last but left his chip from the front of the green woefully short and missed the par attempt.
