Emiliano Grillo storms into the lead in Mexico

Emiliano Grillo made nine second round birdies on his way to a 63 and a four-shot lead at the Mayakoba Golf Classic in Mexico.

The Argentine started Friday a shot behind 18-hole leader Russell Knox and had five birdies before the turn.

He dropped a shot on the 10th but strung together four more birdies to close out his round as darkness fell in Playa del Carmen to go 13 under for the tournament.

Americans Tom Hoge and Tony Finau carded 67 and 66 respectively to share second place on nine under, a shot ahead of Knox who followed his 65 with a 69 which included a bogey at the last.

England’s Ben Taylor looks set to play into the weekend, with his 69 good enough for a tournament score of one under, where the projected cut line will fall.

However, Brooks Koepka carded a second consecutive par 71 and looks as if he will miss out, alongside Rickie Fowler and Graeme McDowell.

Play was suspended at around 7pm local time with several players still to complete their second round.
