Jordan Spieth

Jordan Spieth is now the world's top-ranked amateur, according to the R&A World Amateur Golf Ranking. Spieth, the low amateur at last week’s U.S. Open, took over the top spot after Patrick Cantlay turned professional.

Spieth, a member of last year’s U.S. Walker Cup team, finished 21st at Olympic Club. He also made the cut at this year’s Valero Texas Open, finishing 41st. He was a quarterfinalist at the 2011 U.S. Amateur and Western Amateur, and won last year’s U.S. Junior to become the only player other than Tiger Woods to win that title multiple times. He also won in 2009.

Spieth, who recently completed his freshman year at Texas, finished No. 2 in the Golfweek/Sagarin College Rankings this season, including three victories.

Washington senior Chris Williams moved from sixth to second in the R&A rankings after a 10-shot victory at the Washington Amateur. Stanford sophomore Patrick Rodgers is third, followed by two-time Asian Amateur champion Hideki Matsuyama and Daan Huizing.

Thomas Pieters, the NCAA champion, improved from 11th to ninth with his victory at the Monroe Invitational.

Alabama’s Bobby Wyatt improved 16 places, to 15th in the R&A rankings, after his victory at the Sunnehanna Amateur Championship.

Beau Hossler’s reward for playing all four rounds of the U.S. Open (T-29) is a move of 55 places up the world ranking, to 22nd.
