Fourth successive victory hardens USA's form
Few runs of form are as clear-cut as the one USA are on, four wins from four.
Holding second place, Haiti have 9 points and only the leaders ahead of them. Not once have the hosts lost on home soil, where they have won 2. Goals have come freely for the hosts, who have struck 11 times across their past five matches.
A goal in each of 5 consecutive fixtures underlines the reliability of USA in the final third. Successive clean sheets have added a welcome firmness to the visitors' defending. Enough was done by the visitors to beat Canada 1-0, if only just. 3 of the last 4 meetings between the two sides have gone to USA.
