Canada has made it two straight wins over the U.S.A. with a 27 to 7 win in Glendale, Colorado Saturday night.
While Canada lacked a lot of possession, Crowley was happy with with his team's stifling defence.
"First half we killed ourselves with penalties which kept them in the game and we were down to 13 men for a while," Crowley said. "The second half we tidied up a little bit and we still didn't create a lot but the scrambling defence was outstanding. We did fall off a few first-up tackles but our scrambling defence was a feature and that saved us in the end."
Crowley was happy to leave the two-test series with two wins, but knows the team has to build further to impress at the Rugby World Cup.
"We would have enjoyed a little bit more possession, we didn't create heaps because of our lack of the ball," Crowley said. "We've got a lot of work to do but the pleasing thing is we've come away from this period with two wins."
After a stuttering first half that saw the Americans with the lions share of possession - Canada held a slim 10-7 lead after forty minutes. Centre DTH van der Merwe executing a larcenous steal at mid-field and turned it into a fifty metre scamper for the first points of the game after just five minutes.
The US scored a try from a chip and chase effort in-goal that Blaine Scully managed to drop on before the dead ball line.
Pritchard added a penalty just before half to increase the lead.
The score was impressive considering the USA was up to a two man advantage as Jamie Cudmore and then Chauncey O'Toole were given yellow card infractions. Despite the numbers - the USA could not convert the pressure into points - and with Canada back at full strength the attacks came frequently and with great effect.
Aaron Carpenter was the benefactor of great interplay between van der Merwe and Phil Mackenzie - as the duo netted nearly sixty metres - with Mackenzie presenting the ball to Carpenter ten metres out for a big finish. Carpenter picked up the ball and carried a US tackler across with him for a 20 - 7 lead with the Pritchard conversion.
Then DTH van der Merwe showed his footballing skills running some forty metres before nudging the ball in-field with his right foot. Phil Mackenzie timed it just right to toe the ball across the line and fall on it for the final Canadian try.
Canada beat the USA 28-22 last week in Toronto - but the overall performance in Denver was an improved effort showcasing some of the pace available in the Canadian backline.
Canada next travels to Australia for a pair of warmup matches before carrying on to New Zealand and the 2011 Rugby World Cup.
