Matt Wallace is tied for the lead at the Mexico Open after a late burst during his second round at Vidanta.
The Englishman hit a five-under-par 66 in his first round to lie three shots off the lead in the PGA Tour event.
Wallace gained one shot through the first 10 holes on day two but three birdies and an eagle in the last eight holes helped him card a 65.
It leaves him 11 under at the halfway stage, in a four-way tie with Sami Valimaki, Alvaro Ortiz and Jake Knapp.
“My iron play was great, putting was really nice,” Wallace said. “I managed my game at the end there really well.
“On four I hit a great driver, four-iron to nine feet and missed that, but took a lot of positives from those two shots into the last five holes, which I managed to play really nicely.”
Overnight leader Erik van Rooyen is one shot back after shooting a 69, which included two birdies in the final four holes.
