Joins fellow Mexican Abraham Ancer in the Royal St George’s line-up after a climb into the world’s top 50 and a first PGA Tour title last November at the Vivint Houston Open, where a closing 65 gave him a two-stroke victory over world No 1 Dustin Johnson and Hideki Matsuyama.
Ortiz went into the event, his 118th on the circuit, ranked 160th and moved up 95 places.
He represented his country in the 2010 and 2012 Eisenhower Trophy World Amateur Team Championships, finishing runners-up to the United States on the second occasion in Turkey with teammate Sebastian Vazquez taking individual honours.
After turning professional he won three times on the Web.com Tour in 2014, being voted their Player of the Year and gaining promotion to the main tour.
He lost his card after a poor 2016 season, but came back strongly and his Houston success earned him a Masters debut in April two years after his younger brother Alvaro, just 19 at the time, finished a superb joint 36th there. He had earned an invitation to Augusta National by winning the Latin America Amateur Championship three months earlier.
Carlos first moved into the top 50 with a tie for fourth at February’s Phoenix Open.
