KNOCKOUT ROUND BREEZE: The Whitecaps steamrolled the San Jose Earthquakes on Wednesday in the Knockout Round at BC Place by way of a commanding 5-0 result. It was the franchise’s first MLS playoff victory.

DROUGHT OVER: Whitecaps forward, and former Seattle Sounder, Fredy Montero scored the opening goal in the 33rd minute for Vancouver on Wednesday, the first of his MLS playoff career. Montero spent four seasons in Seattle from 2009-12, but he never found the back of the net in 10 career postseason matches.

TROUBLESOME TRIO: Attackers Montero, Cristian Techera and Yordy Reyna led the Whitecaps in goals this season, and in the seven matches they’ve started together, no opponent has kept all three off the scoresheet nor defeated Vancouver.

COUNTERATTACKS AND SET PIECES: The Whitecaps’ M.O. all season has been to concede the majority of possession and then blitzkrieg in the other direction after forcing a turnover. Pacey midfielders Techera and Reyna lead the charge and bury opponents’ mistakes. Vancouver also capitalizes on set pieces — two of the Whitecaps’ five goals on Wednesday came from corner kicks and a third from a direct free kick — with aerial threats Kendall Waston and Tim Parker among others.
