Scotland’s world No. 34 won the seventh PSA Tour title of his career Saturday, defeating Mexico’s Arturo Salazar in the final of the U.S. Pro Series Racquet Club Pro Series at the Racquet Club of St. Louis in Missouri.

The fourth iteration of the tournament saw the prize money elevate from $10,000 in 2014 to $15,000 in 2015, drawing a high-caliber field of professionals to the gateway to the west.

While Clyne was predicted to reach the final as the top seed, the surprise of the tournament came in the form of unseeded Mexican Arturo Salazar, world no. 113, who forged a path to the final at the expense of American four seed Chris Hanson in the quarterfinals and English two seed Eddie Charlton in the semifinals.

Salazar, former world No. 36, proved to be a formidable challenge, forcing the favored Scotsman into a decisive fifth game in the final. Salazar earned a 6-1 lead in the fifth, but Clyne chipped away at the lead until pulling ahead 9-7. Two errors from the Mexican clinched the title for Clyne.

The RC Pro Series title is Clyne’s first U.S. Pro Series title, and first title in the United States since the Charleston Challenge in 2008.
