Another late goal doomed the Houston Dynamo as Kevin Doyle scored the game-winner for the Colorado Rapids in a 2-1 win on Wednesday at Dick’s Sporting Goods Park.

The Dynamo (32 points, eight games remaining) trail the Seattle Sounders (35 points, eight games remaining) and San Jose Earthquakes (35 points, nine games remaining) for sixth place and the final playoff spot in the Western Conference.

Three important referee decisions may have gone against the Dynamo as they ended a three-game road trip with only one point.

The first call came in the 19th minute as Alex Lima, starting at left back for the first time this season, slid to block a cross from Vicente Sanchez, who cut the ball back to his left foot on the inside edge of the penalty area. Referee Drew Fischer judged that ball rolled made contact with Lima’s hand or arm, and the Rapids were awarded a penalty, despite replays not decisively showing a handball.

Sanchez smashed his penalty kick into the side of the net for a 1-0 Colorado lead.

The Dynamo pushed back and enjoyed a healthy spell of possession in the attacking end that ended with Nate Sturgis slipping a pinpoint cross targeting Will Bruin at the back post, but Rapids defender Bobby Burling lifted his arm to deny Bruin a header. Fisher awarded the Dynamo a penalty but decided a yellow card was fair punishment for Burling, instead of a possible red card.

Brad Davis converted the spot kick, driving it down the middle and into the net as goalkeeper Clint Irwin’s trailing foot clipped the ball on its way in. The equalizer was Davis’ second goal of the season and Houston’s first penalty goal of the year.

After halftime, the frequency of chances slowed for both teams until Colorado seized the winning goal in the 79th minute. Center back Sean St Ledger dribbled forward from midfield and worked a give-an-go with Dillon Serna on the right flank. St Ledger ran past several Dynamo defenders to win the ball at the end line, and despite Houston’s claims the ball crossed the end line before he crossed, play continued as St Ledger lofted a ball in front of goal, where Doyle drove past David Horst to head the winning goal from four yards.

Houston conceded all five goals on the three-game road trip after the 65th minute, including two in New England on Aug. 15, two in Portland on Friday, and Doyle’s game-winner on Wednesday.

The Dynamo struggled to create chances, with just six shots on the night, with four coming from Davis.

Houston played the match without four probable starters due to injury: Ricardo Clark (hamstring), DaMarcus Beasley (calf), Raul Rodriguez (heel contusion) and Kofi Sarkodie (bone bruise).

The Dynamo return home to host Vancouver Whitecaps FC at 8 p.m. CT on Saturday, at BBVA Compass Stadium.
