The Agua Caliente Open was a golf tournament on the PGA Tour first played in 1930 in Tijuana, Mexico. The inaugural event, which was won by Gene Sarazen, offered the largest purse to date — $25,000 with a $10,000 winner's share. The tournament had a second incarnation briefly in the 1950s with the last two events played under the name Tijuana Open Invitational.
