Tigres remained at the top of the Liga MX table with a 2-1 win over San Luis at the Estadio Alfonso Lastras on Saturday.
Lucas Lobos had given visiting Tigres the lead in the 12th minute, but San Luis equalized through Yasser Corona 13 minutes later.
The two sides remained tied until the 58th minute when Luis Garcia popped up with what proved to be the game-winner.
