Three years after the most memorable PK in MLS history, the Portland Timbers and Sporting Kansas City are facing off in a playoff rematch from 2015.
Instead of both teams fighting in a play in game, they will have a two game series in the Western Conference Finals to determine who advances to the last match of the season.
In their last playoff meeting, Portland escaped victorious in a thrilling penalty shootout that went eleven rounds and saw a Kansas City attempt ricochet off both posts, a shot that would have sent them forward.
Sporting KC has had to deal with disappointment in the play in game over and over, having been eliminated at this stage three years in a row. This year, KC earned the best record in the West, sending them straight to the Western Conference Semi-finals in a match up against Real Salt Lake.
After a first leg 1-1 draw, Sporting pulled away earning an easy 4-2 win in front of their home crowd.
Meanwhile, a rivalry matchup between the Timbers and the Seattle Sounders created the most dramatic series of the week.
The first leg, hosted by Portland, saw the Timbers take care of business in front of the home crowd with a 2-1 win, creating an uphill battle for Seattle.
Leg two remained gridlocked throughout the entire first half. Seattle dominated possession, but neither could create the breakthrough they needed.
As it happens so often, the drama of the series unfolded in the final 20 minutes.
With the match tied at 1-1, Portland had one foot in the Western Conference Finals. However, three minutes into stoppage time, Seattle would earn a penalty kick. Easily put away by Nicolás Lodiero, the match would be going to overtime.
Both teams managed to tack on another goal, forcing penalty kicks for the 3-2 match, tied 4-4 on aggregate.
Portland came into the shootout and executed, making their first three. The post and the quick hands of Jeff Attinella would bring the PK shootout tally to 3-1 for Portland.
In the final round, Portland led 3-2, giving forward Dairon Asprilla a chance to send them through.
A powerful but centered penalty would brush the hands of goalkeeper Stefan Frei then fly into the back of the net.
It has been three years since Portland has reached the Western Conference Finals, the same year they eliminated Sporting KC and the same year they went on to become MLS Champions.
Portland and Kansas City last played in August, where Portland took a 3-0 beat down on the road. With one of the best defenses in the league, Kansas will not give Portland an easy win.
