Former world number one Simona Halep emphatically dispatched unseeded Petra Matric 6-1 6-1 in Wednesday's quarter-final at the Indian Wells Open.

Halep landed 75 per cent of her first-serves and won those points at a rate of 82 per cent (27/33).

Martic's serve commanded much less respect, as she landed 69 per cent of her first-serves, but only won 36 per cent of those points (8/22).

After holding in her first service game, Martic allowed Halep to rattle off six consecutive games, with three double-faults assisting her Romanian opponent.

With the win, Halep booked a semi-final matchup against Poland's number three seed Iga Swiatek after she prevailed in her meeting with American Madison Keys in similar fashion.
