Tucson Open

The Tucson Open was a golf tournament in Arizona on the PGA Tour from 1945 to 2006, played annually in the winter in Tucson. It was last held at the Omni Tucson National Golf Resort in late February, with a $3 million purse and a $540,000 winner's share.

History
Since the event's inception in 1945, it had been played at a series of courses in Tucson. The first eighteen editions were at El Rio Golf & Country Club, which was purchased by the city in 1968 and is now El Rio Golf Course. In 1963, the event moved to Forty Niner Country Club in 1963 for two years, then began its lengthy relationship with its last location, known at the time as Tucson National Golf Club, which hosted through 1978. It moved to Randolph Park Golf Course in 1979, returned to Tucson National in 1980, then back to Randolph Park for the next six.

From 1984 to 1986, the Tucson Open was contested at match play and was held concurrently with a Senior PGA Tour match play event, the Seiko-Tucson Senior Match Play Championship The 1986 event was played using a Medal match play format.

In 1987 and 1988 the event was played at the TPC at Starr Pass but was not held in 1989. When the event resumed in 1990, it was played at two courses each year from that year's event until 1996. One used every year was the TPC at Starr Pass (renamed Starr Pass Golf Club before the 1993 event). The TPC at Starr Pass shared time with Randolph Park in 1990; from 1991–96 the Tucson National GC was the other course used.

In 1997, the event changed to the more traditional format of 72 holes played at only one course, and has been played since that year at the renamed Omni Tucson National Golf Resort & Spa.

In later years, it was an alternate event, opposite the WGC Match Play championship, then held at La Costa in Carlsbad, California. Because the top 64 ranked players in the world are invited to the WGC event, it weakened the field considerably for Tucson. The match play tournament moved to Tucson in 2007 as a "merging" of sorts between the two tournaments, and stayed through 2014.

On the PGA Tour Champions, the Tucson Conquistadores Classic made its debut in 2015, and is held at the Omni Tucson National Resort in mid-March.

 * 1977: Bruce Lietzke earns the first of his thirteen career PGA Tour wins by defeating Gene Littler on the fourth hole of a sudden death playoff.

Hal Sutton hits a six-iron for his second shot on the 9th hole directly at the green. The ball slammed into the cup without touching the green and embedded itself in the lip of the hole. Since part of the ball remained above the level of the hole, it was ruled that Sutton had not holed out. He had to replace the ball and putt it in for a birdie.
