Justin Thomas and Patrick Reed are in a showdown for the second time in the calendar year.
Thomas, who won the Sentry Tournament of Champions in January in a playoff over Reed, shot a six-under 65 in Saturday's third round of the 2020 World Golf Championships-Mexico Championship at Club de Golf Chapultepec just outside Mexico City.
He is 15-under for the tournament and one stroke ahead of Reed, who shot a four-under 67, atop the leaderboard after a back-and-forth third round.
Here's a look at the pairing and other top contenders, per PGATour.
