Liguilla field set after Gignac hat trick, America defeat

Reigning champion Tigres is into the Liga MX playoffs, while runner-up America is out after a wild Saturday night of Round 17 matches.

The weekend started with Tigres forward Andre-Pierre Gignac scoring his first hat trick since November and leading his team to a 5-1 victory over Queretaro that clinched a spot in the postseason.

Club America, which fell to Tigres in December's Apertura final, won't be back in the postseason after falling 3-2 to Pachuca. A draw would've been enough to get Las Aguilas into the "Gran Fiesta", and Manuel Perez's double with goals in the 68th and 70th minutes seemed to have done just that. But Tuzos center back Oscar Murillo poked his club back ahead in the 79th to eliminate America from post-season play.

Pachuca was hoping a victory would be enough for it to sneak into the final eight, but Monarcas' victory over Monterrey, combined with their superior goal difference, gave the Morelia side the final postseason spot.

Club Tijuana will be the No. 1 seed after its 1-0 victory Saturday over Veracruz. The win means Xolos are the first club in league history to finish as the leader in consecutive short tournaments, though they'll look to better the first-round elimination they suffered in the Apertura.

Chiapas relegated despite victory

Just behind them sit Monterrey and Chivas, though Santos Laguna or Toluca could jump into second place with a victory in Sunday's nightcap. Atlas sits fourth but can finish no better than fifth - meaning the Zorros will host the first leg of their quarterfinal at Estadio Jalisco.
