Three players -- including Wyoming resident John Hornbeck, winner of the 2018 CGA Senior Match Play -- opened with 73 and share third place. Owen Ellis of Flatirons Golf Course and Mark Spenner of Front Range Golf Club are also at that number.
The last two champions in this tournament carded first-round 74s -- Steve Ivan of Patty Jewett Golf Course (winner in 2017) and Kevin Ott of The Club at Rolling Hills (2016). John Hull of Collindale Golf Course also started with a 74.
The field will be cut from 84 to the low 40 players and ties after Wednesday's second round. The tournament, limited to players 52 and older, will conclude on Thursday.
