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 Corey Prugh of Manito CC holds the record for the most wins (2009, 2011, 2013 & 2015). Amateur Derek Bayley set the 54 hole-tournament record of 189 (27-under par) at at MeadowWood GC in 2016. The biggest winner at this championship is the Vanessa Behan Crisis Nursery charity – $3.65 million has been donated since the tournament’s inception.
