Australian Ajla Tomljanovic has moved into the quarter-finals of the Japan Open with a composed win over veteran Kimiko Date-Krumm.

Seventh-seeded Tomljanovic, at 22 half the age of her opponent, came home strongly against the Japanese after sustaining an early break.

She went on to win 7-6 (7-5) 6-3.

Tomljanovic will now play Madison Brengle for a spot in a semi-final.

She’ll fancy her chances against the American after downing her 6-1 6-1 at Strasbourg in May.

Brengle had overpowered Japanese wildcard Nao Hibino 6-1 6-2 to advance to the last eight.

She won six of eight break points at Ariake Colosseum to see off Hibino, one of three players from the host country to exit the tournament on the third day.

Sixth-seeded Christina McHale, also of the US, beat Risa Ozaki 6-1 7-5.

Also, Yanina Wickmayer of Belgium beat fifth-seeded Johanna Larsson of Sweden 7-5 6-3.
