The 2001 United States Open Championship was the 101st U.S. Open, held June 14–18 at Southern Hills Country Club in Tulsa, Oklahoma. The U.S. Open returned to Southern Hills for the first time since 1977. Retief Goosen won the first of his two U.S. Open titles in an 18-hole Monday playoff, two strokes ahead of runner-up Mark Brooks. The tournament was also notable for ending defending champion Tiger Woods’ run of four consecutive major championship wins, the “Tiger Slam;” he finished seven strokes back in a tie for twelfth. Woods reclaimed the U.S. Open title the following year, and won the PGA Championship at Southern Hills in 2007.
