Mexico's Alvaro Ortiz shot a 1-under 70 Monday to take the 54-hole lead at the Latin America Amateur Championship in Chile.
At 4 under for the week, he leads by one over over Argentina's Jaime Lopez Rivarola, Chile's Toto Gana and Joaquin Niemann, and Guatemala's Dnaiel Gurtner.
Ortiz is the younger brother of three-time Web.com winner Carlos. Alvaro, a senior at Arkansas, finished tied for third at the LAAC in 2016 and lost in a three-way playoff last year that included Niemann and Gana, the champion.
Ortiz shared the 54-hole lead with Gana last year and they will once again play in the final group on Tuesday, along with Gurtner, a redshirt junior at TCU.
