The top ten comes off the back of four consecutive missed cuts as the 45 year old chases a return to the PGA Tour.
Coles, a five time winner on the Web.Com Tour, played the PGA Tour in 2003, 2005 and 2007, 2008 and 2012, earning nearly US$3 million in career earnings in the US.
One of the shorter hitters on either the PGA or Web.Com Tour, Coles' persistence has carried him a long way and this week's effort will see him advance to 45h on the money list.
The winner of the event, Homa, a Walker Cup player in 2013, recorded a final round of 63 to win the US$117,000 and advance to 9th on the money list.
Nick O'Hern, Aron Price, Steve Alker and Peter Lonard were other Australasians to make the cut but finished well back.
