MEXICO CITY, Dec 10 (Reuters) - Atlante beat Pumas UNAM 2-1 to win the Mexican championship for the first time in 14 years and only six months after moving to the resort of Cancun. Clemente Ovalle crashed in a left-foot shot from outside the area in the 86th minute to score the winner in the second leg of the Apertura championship final late on Sunday. The first leg had ended goalless. Venezuela striker Giancarlo Maldonado gave Atlante the lead in the 59th minute, breaking clear of the defence and rounding goalkeeper Sergio Bernal to score his 18th goal of the championship. Pumas levelled 10 minutes later when Ismael Iniguez headed in a rebound four minutes after coming on as substitute. 'This is a great moment for all the Atlante supporters, who have had nothing to celebrate for a long time,' said coach Jose Guadelupe Cruz, who was a player when Atlante won their previous title in 1993. 'This was a fair reward for the team's work and consistency.' Atlante moved their franchise from Mexico City to Cancun in July because of poor attendances at the Azteca stadium. Two separate championships -- the Apertura and Clausura -- are played in the Mexican season.
