Canada beat USA on the first innings in Florida to keep hold of the Auty Cup.
The visitors had the better of a low-scoring two-day match with Raza-Ur Rehman's stand-out innings of 88 proving the difference between the sides.
The right-hander, the only batsman to pass 30 in the match, then added 54 not out on the second day.
USA never threatened to surpass Canada's first innings of 196, slipping to 114 not out with Rehman again making his mark by running out top scorer Karan Ganesh for 29. Manny Aulakh (2-29) was chiefly responsible for reducing USA to 23-3 before Junaid Siddiqui (3-34) ran through the middle order. Daesrath Damodar (2-1) then helped to polish off the tail as Ganesh's fourth-wicket stand of 41 with Timothy Surujbally (24) was the only partnership of substance.
Rehman had earlier been the last man out in Canada's first innings after batting for 197 balls and hitting eight boundaries. Siddiqui helped his senior partner add 52 for the ninth wicket in a pivotal stand.
Hiral Patel (24) and Amarbir Hansra (21) were the other scorers of note for the away team.
After dismissing USA cheaply, Canada were left needing to bat out the rest of the match on day two to claim a first-innings victory - a feat they duly achieved despite an early collapse.
Rehman's half-century saw them to safety from a perilous position of 60-6, with time still left for an unlikely USA victory charge. That notion was extinguished once Hansra (28) helped Rehman add 41 for the seventh-wicket in 15 overs, Canada finishing on 159-8.
Danial Ahmed (4-34) and Timil Patel (4-50) fought hard for the home team but it was not enough to wrest the Auty Cup away from Canada, who have now held the title since 1992.
A 50-over fixture between the nations will now take place on Friday November 16 followed by two Twenty20 clashes on Saturday November 17. All games will be staged at Central Broward County International Cricket Stadium in Lauderhill.
