The Valero Texas Open is an official tournament on the PGA Tour. It dates back to 1922 when it was first called the Texas Open; San Antonio-based Valero Energy Corporation took over naming rights in 2002. It is played at The Oaks Course at the TPC San Antonio. In 2003, it was the site of the 72-hole PGA Tour record 254 shot by Tommy Armour III. Many big-name players have won this tournament, including Sam Snead, Ben Hogan, and Arnold Palmer, who won it three years in a row. It has always been considered a tournament where it is quite easy to shoot low.
