The 37-year-old Luiten is in prime position at 14 under to claim his seventh European tour win – his first since 2018. Dutch compatriot Daan Huizing was his nearest challenger after a 66 in the third round.
“Today was pretty much flawless,” Luiten said. “I didn’t really get into trouble that much and if I did miss the fairway I hit a great shot and still created a birdie chance. I made some nice birdies coming down the last four or five holes.
“It would mean a lot to me to win but that’s not just me, that’s everybody. I need to keep my head cool.”
