The match, arranged as an additional fitness opportunity following Wednesday's win in Orlando, saw England score five of their six goals in the second half. Toney's treble included a long-range effort that onlookers described as a "worldie" — continuing the pattern of spectacular strikes from distance that has characterised England's preparation matches in North America.
Toney's inclusion in Tuchel's World Cup squad had surprised many observers given his lack of recent Premier League football, but the hat-trick represents the clearest possible statement of intent from the former Brentford forward that he intends to be considered for involvement once the tournament begins.
Goals also came from Jordan Henderson, Ethan Nwaneri and Liverpool prospect Rio Ngumoha, with Ngumoha's contribution also described as a long-range strike of real quality.
Ngumoha's involvement carries an unusual subplot. The 17-year-old has been brought along by Tuchel as a training squad member to provide additional support and sharpen the senior players in practice matches — but, under tournament eligibility rules, he cannot be added to England's official 26-man World Cup squad regardless of his form in these fixtures.
The two results in 48 hours — nine goals scored, none conceded — represent the most emphatic possible send-off for Tuchel's squad before the serious business begins. England open their World Cup campaign against Croatia in Kansas City on June 17.
Whatever questions remained about squad depth heading into the tournament, the supporting cast has just delivered an emphatic answer of its own.
