CHESTER, Pa. (AP) — Rookie defender Alexandros Katranis scored in the 89th minute and Real Salt Lake rallied to beat the Philadelphia Union 2-1 on Saturday night.

Real Salt Lake (5-2-3) knocked off the league’s last unbeaten club, handing Philadelphia (3-1-4) its second loss in the last 40 league matches at home under manager Jim Curtin. The Union had outscored their opponents 88-23 in the previous 39 home contests.

Real Salt Lake took a 1-0 lead in the 34th minute when second-year midfielder Andrés Gómez used an assist from Cristian “Chicho” Arango to score for a second straight match and for the fourth time this season. Arango notched his seventh assist after entering play in a three-way tie for the league lead with Inter Miami’s Lionel Messi and Dante Vanzeir of the New York Red Bulls.

Philadelphia evened the score early in the second half on a goal by Dániel Gazdag in the 50th minute. Quinn Sullivan earned an assist on Gazdag’s left-footed shot from close range. It was the fifth goal of the season for Gazdag with four scores coming in the last five matches.
