2017 Liga MX Clausura Playoffs
Quarterfinals, First Leg
May 10, 2017

Atlas 1, Guadalajara 0
Matias Alustiza 30’ pen 

• Matias Alustiza’s penalty kick at the half-hour mark was enough to hand Atlas a 1-0 win over Guadalajara-city rival Chivas at the Estadio Jalisco.
• Atlas forward Daniel Alvarez was brought down in the Guadalajara area in the 28th minute, and two minutes later Alustiza converted the spot kick for his ninth-career goal against Chivas.
• Alustiza now has nine goals the 2017 Clausura (8 regular season, 1 playoffs) and has scored in three of his last four matches.
• Guadalajara is winless in its last six matches (0W-3D-3L).
• Guadalajara will host Atlas in the second leg on Sunday at the Estadio Chivas.

Morelia 1, Club Tijuana 0
Miguel Sansores 11’

• Morelia stunned top-seeded Club Tijuana with a 1-0 win thanks to Miguel Sansores’ 11th-minute goal.
• Sansores was able to get on the end of Jefferson Cuero’s cross from the left and slid in a right-footed shot that may have taken a deflection off Club Tijuana goalkeeper Manuel Lajud, before seeking inside the right post.
• The news wasn’t all good for Morelia though, as team and Clausura leading scorer Raul Ruidiaz (9 goals) left the field in the first half with an injury.
• Morelia has won three straight games, allowing only one goal over that stretch.
• Club Tijuana has lost in its last two away games and was shutout in both.
• Club Tijuana will host Morelia in the second leg on Sunday at the Estadio Caliente.
