Tigres went down to nine men but managed to score twice and hold off a gutsy Cruz Azul team.
Gaston Fernandez and Lucas Lobos were each sent on their way. Fernandez, though, contributed with the match-winner before exiting in the 62nd minute. Tigres' win was their first home win in nearly six months.
For Cruz Azul, the loss was just their second in their last nine trips to Estadio Universitario.
Tigres, though, did not look like it would snap their home drought. At halftime, Tigres had gone down to 10 men after Lucas Lobos stepped on a Cruz Azul player.
But Tigres used their disadvantage to their advantage. Five minutes into the second half, Jesus Molina fed Fernandez, who knocked a shot past Jose de Jesus Corona.
Tigres doubled their lead eight minutes later when Itamar Batista took care of business on his own. Batista shook off a pair of defenders and beat Corona to give Tigres a two-goal edge.
Fernandez, though, bid adieu in the 62nd minute after a rough challenge.
Down two men, Tigres played in a more defenisve posture and were able to kill off the game.
