On July 16, 1978, Victor Regalado won the Quad Cities Open over Fred Marti. His 269 total was good enough to capture the $150,000 first place prize. 

Regalado was born in Tijuana, Mexico, and won two San Diego Amateurs early in his golf career. He would turn professional in 1971.

When he won his first event, the Pleasant Valley Classic, in 1974, he became the first Mexican born player to win on the PGA Tour. During his career, Regalado had 29 top 10's on the PGA Tour, five 2nd place finishes, and the two victories. 

In 1981, Regalado had a part in one of the longest sudden death playoffs in PGA tour history. At the Quad Cities tournament that year, Dave Barr was victorious over Regalado, Woody Blackburn, Dan Halldorson, and Frank Conner. It took 8 holes.
