Stosur opens Japan Women's Open with win

OSAKA, Japan, Oct. 11 (UPI) -- Top-seeded Samantha Stosur opened defense of her Japan Women's Open tennis title with a straight-set victory Monday.

Stosur breezed past wild-card entrant Sachie Ishizu 6-0, 6-3 in 56 minutes. Stosur took 72 percent of the points in first set in establishing control and didn't face a break point in moving into the second round.
