San Jose, USA, 15 February 2013 |

Australians Marinko Matosevic, Matt Ebden and Lleyton Hewitt have gone down at the SAP Open in San Jose, California on Thursday.

Hewitt fell 7-6(6) 1-6 7-6(4) to American No.3 seed Sam Querrey, in a match that took two hours and 15 minutes to complete.

The 31-year-old Australian was on the back foot against the six-feet-six Querrey, who smacked 20 aces throughout the match.

Meanwhile, Ebden battled for almost two-and-a-half hours against No.8 seed Xavier Malisse, eventually falling 5-7 7-5 7-6(1).

The Western Australian led in almost every statistical department, banging 12 aces to 1, landing more first serves, and winning more points when his first serve went in.

Yet the experienced Belgian, who will turn 33 this year, played better in the clutch.

Malisse sealed victory and ensured his progression through to the quarterfinals, where he will face second seed John Isner of the United States.

Earlier in the day at the ATP 250 event, unseeded Colombian Alejandro Falla upended Matosevic, the tournament’s seventh seed.

Matosevic struggled on serve, producing more double faults than aces while winning less than 60 per cent of first serve points.

Falla posted a 6-4 6-4 win in just under 90 minutes to move into the final eight, where he will take on Querrey.
