Nico Echavarria claimed the Zozo Championship for his second PGA Tour victory, shooting 3-under 67 on Sunday to win by a shot over Max Greyserman and Justin Thomas. Echavarria, a Colombian who played at the University of Arkansas, birdied two of the final three holes — including the 18th — to add to the title he won last year at the Puerto Rico Open. Echavarria said the victory last year helped build his confidence.
