Andy Murray is relishing the prospect of a "tough test" against Novak Djokovic after booking a semi-final showdown with the world number one at Indian Wells.
The Scot made it 10 wins out of 10 against Feliciano Lopez - and 497 for his career to surpass Tim Henman as Britain's most prolific male player of the open era - with a one-sided 6-3 6-4 victory in the BNP Paribas Open on Thursday.
Serbia's Djokovic was handed a progression by walkover after Australian Bernard Tomic pulled out with a back injury.
And Murray said on Sky Sports: "Against him you're going to have to a play high-quality match, you can't have any part of your game not working against him.
"He'll obviously be fresh with a couple of days' rest so it'll be a tough test but it's one I'm looking forward to."
Murray's perfect 10 against Lopez fits in with his good overall record against left-handed players - a fact he puts down to his elder brother Jamie.
"My brother's a lefty so when I was a kid it's all I practiced against up to the age of 12," he said. "I see the spin almost more naturally than against right-handers.
"I passed very well today and that stopped him feeling comfortable up to the net, it meant he spent a bit more time at the back and I was able to dictate the match."
Later, Sabine Lisicki saved three match points before taking out defending champion Flavia Pennetta to reach a semi-final against Jelena Jankovic.
The German was given a stern examination in the first set but clinched it before Pennetta of Italy punished some indecision to take control of proceedings, winning the second set on a tie-breaker.
Lisicki, a former Wimbledon finalist, struggled to find her serve in the decider and was forced to deny Pennetta the winning shot on three occasions before belatedly discovering her serve and rallying to a 6-4 6-7 (3/7) 7-6 (7/4) victory.
She told BT Sport: "It's unbelievable. It's such a great feeling.
"She also saved a match point in the second set with an unbelievable backhand and there wasn't much I could do there."
Her opponent in the last four is Jelena Jankovic, who was beating Lesia Tsurenko 6-1 4-1 before the unseeded Ukrainian retired due to an ankle injury.Reuse content
