TACOMA — Seattle Sounders 2 have had a rough go of it for the last two, three, probably four months, but there have been signs of the young developmental side figuring things out the last two weeks. Those signs came to fruition against Las Vegas Lights FC — a side S2 lost to 4-1 a month and a half ago — with a 3-0 win at Cheney Stadium on Thursday as S2 out-paced and out-shot Vegas. S2 got goals from Antonee Burke-Gilroy, David Estrada and Lamar Neagle and played more than a half up two men, but were in control throughout.
