Indian Shubhankar Sharma upstaged the big names to open up a two-shot lead at the halfway mark of the WGC-Mexico Championship at Golf Club de Chapultepec.
The 21-year-old eagled the first hole on the way to an excellent 5-under-par 66 on Friday and sits at 11-under after 36 holes of the no-cut tournament.
Spaniards Sergio Garcia and Rafa Cabrera-Bello share second spot with American Xander Schauffele on 9-under, while it's a further two shots back to a group which includes World No. 1 Dustin Johnson and first-round leader Louis Oosthuizen.
Sharma is the youngest golfer in the field this week and is playing in his very first WGC event, although he's turned heads with two wins on the European Tour over the past three months.
Following his opening eagle from tap-in range after he'd driven the green on the 320-yard opener, Sharma bogeyed the next two holes. But on the inward nine, he hit some superb approaches and made birdies at 11, 12, 16, 17 and 18 to kick clear of the field.
"I'm really happy. I couldn't be in a better situation. Played so well, and the bogeys that I made today were just three putts. Otherwise I just got the ball in play all day and it was great to finish with three birdies in a row," said Sharma.
"I thought about nothing, I just wanted to have fun. It's my first WGC and I was happy that I'll play four days because I missed the cut in the last two events that I played. Even though I missed the cuts, I knew I was playing well. So I just wanted to have fun, and yeah, I've had a lot of fun.
"I worked all my life to come and play at a high stage like this. You have to expect great things from yourself if you want to play at a high stage."
Sharma is 2000/1 to win the WGC-Mexico Championship, with Johnson 800/1, Garcia 1000/1, Schauffele 2000/1 and Cabrera-Bello 400/1.
