A new girls Class 4A state soccer champion will be crowned this year after Fort Worth Arlington Heights knocked out defending champion Denton Guyer 1-0 in the regional quarterfinals Thursday at Farrington Field.The start of the game was delayed for just over an hour by lightning, and then got off to a bit of a sluggish start.Neither team produced any real scoring threats through the first 20 minutes. The best chance came when Hannah Alspach dribbled into the Yellow Jackets area, but she was dispossessed before getting off a shot.After Guyer enjoyed a spell of possession, the game shifted on a foul call in the midfield. Alspachs hard challenge sent Amanda Long to the bench with an apparent injury. On the ensuing restart, defender Audrey Reynolds launched a 45-yard free kick that dropped just under the crossbar and just over the hands of Wildcats goalkeeper Mikayla Renfroe, giving Heights a 1-0 lead.Guyer nearly answered less than two minutes later, when Alspach and Sophie Martin combined inside the Jackets 18-yard box, but keeper Christina Romo managed to smother the ball and end the threat.Heights (17-2) threatened again on a set piece in the 31st minute. Debbie Quintana got her head to a Payton Blanchard corner kick near the back post, but Renfroe was positioned well on her line to knock it down. None of the Jackets players in the area could punch home the loose rebound.Guyer came within inches of leveling the score in the 58th minute on a corner kick. The ball appeared on the way into the goal, but Heights defenders were able to clear from the goal line.While much of the final 20 minutes was played in the Heights end of the field, the Yellow Jackets often pulled 10 players behind the ball and defended strongly to preserve their lead.
