Shelton routs Mensik to reach Canadian Open semis

Aug 11 : Ben Shelton produced one of the standout performances of his career on Tuesday, overpowering Jakub Mensik 6-3 6-1 to reach the Canadian Open semi-finals as the American builds momentum ahead of the U.S. Open.

The hard-serving 23-year-old, a formidable presence on hard courts, dominated from start to finish as every facet of his aggressive game clicked, with Shelton committing just three unforced errors.

After a near-flawless opening set, Shelton fired a backhand winner down the line to break the Czech's serve for a 2-0 lead in the second, punctuating the moment with a thunderous roar.

Shelton sealed the 72-minute win in Montreal when an overwhelmed Mensik sent a backhand long on match point.
