South African Kevin Anderson reached the second round of the Cincinnati Open when he beat Leonardo Mayer of Argentina in three sets on Tuesday.
The fifteenth seed won the match 7-6(5), 3-6, 6-1 in over two hours. The big serving Anderson won the opening set tie-breaker 7-5 in a very close opening set. Mayer upped his game in the second set and tied the match at a set apiece by winning the second set 6-3.
Anderson, though, took control of the deciding set early and going to a 3-0 lead from which Mayer could not recover, and the South African ran out a convincing 6-1 winner.
