MEXICO CITY, May 25 (Reuters) - Santos Laguna, who had scraped into the Mexican Clausura championship title playoffs on goal difference, have upset Guadalajara 3-0 away at the Omnilife to reach the final.
Santos, who played out a goalless draw in the first leg, will be looking for their fifth title in the two-legged final against Ronaldinho's Queretaro this week.
Queretaro beat Pachuca 2-0 in the other semi-final for a 2-2 aggregate result that put them through, thanks to their higher position in the 17-match league phase, where they finished sixth one place above Pachuca.
