SAN DIEGO (AP) — Anders Dreyer and Amahl Pellegrino scored two goals each to help San Diego FC beat the Portland Timbers 4-0 on Sunday night and win their best-of-3 first-round series in the MLS Cup playoffs.

No. 1 seed San Diego plays fourth-seeded Minnesota in the single-game Western Conference semifinals.

Pablo Sisniega made his second career playoff start at goalkeeper for the injured CJ dos Santos and had two saves for San Diego. Dos Santos suffered a broken cheekbone early in the team's penalty-kick shootout loss to Portland last week in Game 2 to force a decisive third game.

Dreyer, on the counter-attack, skipped a volley from the center of the area — off an arcing ball-in played by Onni Valakari — into the net to give No. 1 seed San Diego the lead for good in the fifth minute.
