2021 Texas Open scores: Jordan Spieth in contention after Round 1 in San Antonio as Camilo Villegas leads

Spieth seemed to be clicking on all cylinders on Thursday just ahead of Masters week

SAN ANTONIO (AP) -- Camilo Villegas chipped in twice to highlight a nine-birdie round that earned him an 8-under 64 and the first-round lead at the Valero Texas Open on Thursday. Sung Kang, a 33-year-old South Korean, is two shots back with Cameron Tringale after each had a 66 at TPC San Antonio's Oaks Course. Jordan Spieth, whose struggles the past three years appear to be subsiding after four top-10 finishes the past two months, is three back (67) with Seung-Yul Noh and Hideki Matsuyama. Phil Mickelson dropped to 15 shots back when he had a 10 on the 18th hole -- he took two penalty shots and another three strokes trying to get away from a greenside stream -- and ended with a 79.
