Orange Crush knocked off RSL in the deciding match of the previous round, 4-3 on penalties, while Sporting defeated the top-seeded team in the Western Conference, St Louis City, 2-1 in early November, winning that series 2-0.
Match preview
It was a nerve-racking series against a pesky RSL side, but the Dynamo prevailed on penalties, advancing into the conference semi-finals for the first time since 2017.
At home or away, Ben Olsen usually has two different tactical approaches, operating in a pragmatic mid-block, transitional way on the road but shifting to a ball-dominant strategy in Houston.
He has some workhorses in the midfield that can make that possession approach work, as the Dynamo build from the back efficiently, with strong central midfielders that can create chances from short passes on the ground.
The Dynamo are an impressive 9-1-6 in their last 16 matches across all competitions since August 20, and they were only behind in one of those encounters during that stretch, losing to SKC 2-1 on September 23.
Since the conclusion of the Leagues Cup, Orange Crush lead the league with a +19-goal differential (including the playoffs), conceding just 10 times over that stretch.
Scoring first has been pivotal to their success throughout the domestic campaign, with Houston going 13-0-3 when drawing first blood while winning just once when conceding the opener.
Sporting KC started peaking at the right time and have remained hot in the playoffs, losing just one of their previous seven domestic affairs and qualifying for the conference semi-finals for the third time in the last four MLS campaigns.
It took the newcomers on this squad some time to adjust to the Peter Vermes tactical approach of building through the midfield, but eventually it all seemed to click as Kansas City have been effective at shifting the opposing defence from one side to another to try and get a 1V1 matchup with one of their wingers and a fullback from the opposition.
Down the stretch of the season, Sporting have been effective when counter-pressing to maintain possession in the final third while scoring three or more goals in back-to-back away fixtures.
KC have won eight of their 11 matches played in MLS since the Leagues Cup ended, the second-most domestic victories over that stretch behind Orlando City (10).
From the start of May until the end of the 2023 regular season, Kansas City led the Western Conference in points (41), wins (12) and goals-per-game (1.88), while their seven defeats over that span was the fewest among Western Conference teams.
They have won three of their previous four MLS away matches since September 16 but have never triumphed in a playoff contest at Houston, failing to score in those four encounters.

We say: Houston Dynamo 1-1 Sporting Kansas City (Sporting Kansas City advances on penalties)
Both teams exceeded expectations in the regular season, and they each have a solid midfield shape and match-winners that can make the difference up front.
If the match is as close as we anticipate, it could come down to penalties, giving the visitors the edge as Tim Melia has won all seven shootouts that he has been a part of in his professional career.
