Flesch finished in the top ten on the Asia Golf Circuit Order of Merit in 1993, 1994 and 1996. He won the 1997
NIKE Tour Championship to earn a
PGA Tour card for the following season, only the second left-hander to win on what is now the
Korn Ferry Tour. His first win on the PGA Tour was the 2003
HP Classic of New Orleans, but is probably best known for his come-from-behind victory at the 2004
Bank of America Colonial in
Fort Worth, Texas. He has been featured in the top 50 of the
Official World Golf Rankings, reaching a career high of 22nd in 2004. Entering the
2008 Masters Tournament, Flesch was ranked number 107 in the
world rankings. After three rounds, he was in third place at eight-under, three strokes behind leader and eventual champion
Trevor Immelman. Playing in the penultimate pairing on breezy Sunday, Flesch posted a 78 to finish six strokes back, tied for fifth. This strong showing in a major tournament strengthened his world ranking by 28 slots, improving it to number 79. Flesch last played a full season in 2011, then missed the cut in the 12 events he played during the 2012 season. In 2015, he finished T7 at the
Barracuda Championship, his first top ten in four years. He also worked as an analyst for
Golf Channel before returning to competition on the
PGA Tour Champions in 2017. ==Professional wins (13)==
