Peralta strike gives Mexico win amid ref controversy
Mexico has beat Cameroon 1-0 with a second-half strike by Peralta and join Brazil at the top of World Cup Group A with three points.
The Aztecs dominated the game from the kick-off, but were goalless at halftime after Giovani Dos Santos had a neat volley and a header from a corner both ruled out for offside in decisions TV replays showed were wrong.
However, they finally broke through after 61 minutes when a Dos Santos shot was parried by the keeper into the path of Peralta who tucked it in.
Samuel Eto'o clipped a post early on for Cameroon but they did little in attack.
