Hale Irwin is currently the oldest player on the Champions Tour. He may be older than all the players but he can definitely still play at a high level with some of the best golfers to ever do it.
He made his debut on the PGA tour back in 1968 and is still competing to this day. While on the PGA tour, Irwin was known to excel in tournaments when the conditions were the toughest. This was obvious during the 1974 U.S. Open when he was able to secure the win under some of the worst conditions to ever be played in the Open era. He was able to win the tournament with a score of seven over par in the tournament that was later named the "Massacre at Winged Foot."
From 1971 until 1994, Irwin was able to capture the victory at 20 PGA Tour events. Along with being known for his strong performances in difficult conditions he is also the definition of consistent. He holds the fourth best mark in PGA tour history with 86 consecutive tournaments making the cut. This means that he was in the running to win in every tournament he participated in from 1975 until 1978.
He was a well renowned golfer throughout his career and was also given the recognition of being named the captain of the United States team in the inaugural President's Cup in 1994. He was known to be one of the most consistent golfers of his time and still competes at a high level today while 74 years old.
