As teams prepare for the second half of the 2019 Major League Soccer season to heat up, MLSSoccer.com's Bobby Warshaw assembled his Best XI selections for the first half of the season.
Earning a spot amongst the list was Union left back Kai Wagner. The 22-year-old has had a strong debut season for the Eastern Conference leading Union. "Wagner has one of the toughest jobs in soccer – outside back in a 4-4-2 diamond system. The midfield doesn’t provide much width, offensively or defensively, so the entire length of the field is left to the outside backs," Warshaw writes. "Wagner has locked down the left side for the best team in the East."
