South Korean star Son Heung-min scored his first career MLS hat trick roughly a month after his debut in Wednesday night's 4-1 win at Salt Lake. Last weekend, Bouanga scored the hat trick and Son added the extra goal in a 4-2 win at San Jose. 'It's been only two games, but I think we've scored a lot of goals, and we've enjoyed it.' But I think from our standpoint, we've just got to be a bit more physical, especially on the last two goals.'
