Past Champions/Rosauers Open
The Rosauers Open Invitational started in 1988 when a group of Spokane area Golf Professionals realized their goal of bringing a Pacific Northwest Section Major to town, which they achieved by developing a relationship with Rosauers Supermarkets. The tournament has almost always been held at Indian Canyon GC, which was designed by E. Chandler Egan – who also designed Pebble Beach GC. PGA Professional Derek Barron of Tacoma Golf Center recorded Indian Canyon’s competitive course record score of 59 in the 2015 championship. The tournament record of 192 was set by Corey Prugh in 2009. Prugh also holds the record for the most wins (2009, 2011, 2013, 2015). The biggest winner at this championship is the Vanessa Behan Crisis Nursery charity – over $2.6 million has been donated since the tournament’s inception.
