Ahead of this Saturday’s home contest with Philadelphia Union (7:00 p.m MT - Altitude), here are 10 things that you may, or may not, have known.
1. Zac MacMath is set to face his former club for the first time. During four seasons with Philadelphia Union, having been drafted in 2011, MacMath made 103 regular season appearances for the Eastern Conference side. While with the Union, MacMath became the youngest goalkeeper in MLS history to reach 100 career starts.

2. He was in goal for Philly the last time they appeared at Dick’s Sporting Goods Park (pictured right), in the weather-delayed home opener on March 10, 2013.
