MEXICO CITY (REUTERS) - India's Shubhankar Sharma upstaged the biggest names in golf by eagling the first hole en route to a two-shot halfway lead at the WGC-Mexico Championship on Friday (March 2).

In his first appearance in a World Golf Championships event, the 21-year-old added a five-under 66 to his opening round 65 to finish at 11-under 131 for the tournament at Club de Golf Chapultepec in Mexico City.

The Spanish duo of Sergio Garcia (65) and Rafa Cabrera Bello (67) were in a share of second with American Xander Schauffele (68) on nine-under.

First-round leader Louis Oosthuizen (71) backtracked to fall four shots off the pace in a large group also including defending champion Dustin Johnson (66).

Sharma entered the week already ranked first on the European Tour after two early-season victories, in South Africa and Malaysia.
