A field of 64 players got started Thursday at the WGC-Mexico Championship, where the leaderboard has a decidedly international flair. Here's how things look after the first day in Mexico City, as play was suspended late in the afternoon because of inclement weather with Louis Oosthuizen out to an early lead:
Leaderboard: Louis Oosthuizen (-7), Chris Paisley (-6), Xander Schauffele (-6), Shubhankar Sharma (-5 through 16 holes), Rafael Cabrera-Bello (-5), Kiradech Aphibarnrat (-5)
What it means: There were plenty of low scores as players more often than not successfully calculated the elevation adjustments at Club de Golf Chapultepec.
