The Americans just missed out on a medal as they came in just over two seconds behind Poland in the A Final.
Banks sat two-seat and Hack four-seat for the top U.S. boat. At the 500-meter mark, Team USA was in fourth position and would remain there throughout the race. The final time was 5:29.18, while Great Britain won gold with a time of 5:24.11. Germany was a half second behind Great Britain for silver.
Rounding out the race was France in fifth place and Russia in sixth.
This was the second World Championships for Hack, who graduated in June with a degree in political science and was the Pac-12 Athlete and Scholar-Athlete of the Year this past season. Hack earned bronze at the World Championships last year in South Korea. Banks competed in his third World Championships and first since going back-to-back years in 2009 and 2010. Fourth place was his highest career finish at the regatta.
