Yahoo Sports reports: Less than a week ago, Jakub Mensik was pushed away from the court in a wheelchair after collapsing to the clay with cramps. The 6-foot-5 Mensik used his attacking game to end the run of Brazil’s Joao Fonseca with a 6-4, 6-3, 7-6 (3) victory in the quarterfinals Tuesday. It was Mensik’s most convincing performance so far at Roland Garros after struggling physically in the heat wave during the opening week.
