Mexico:TIger Woods has not been eligible for this World Golf Championship since 2014, when he shot 78 in the final round and tied for 25th at Doral. It was his last event before the first of four back surgeries. … This is Woods’ first tournament in Mexico. He will be in the same group as Abraham Ancer, who is in the field with the best world ranking (No. 61) of Mexican players. … Justin Rose, Jason Day and Adam Scott are among those who chose not to play the first World Golf Championship of the year. Rose could lose his No. 1 ranking depending on who wins. … Eddie Pepperell, Aaron Rai and Jake McLeod are making their World Golf Championships debuts. … Russell Knox is the last player to make his first PGA Tour title a WGC event, in Shanghai at the HSBC Champions three years ago. … Americans made it a clean sweep of the WGCs last year with Mickelson winning in Mexico, Bubba Watson at the Match Play, Justin Thomas at Firestone and Xander Schauffele in Shanghai. … Since this event began in 1999, it has gone to a playoff only three times — Woods beat Miguel Angel Jimenez in 1999 at Valderrama and John Daly in 2005 at Harding Park, and Mickelson defeated Thomas last year.
