Tomas Berdych is relishing what promises to be a hotly-anticipated rematch with Andy Murray today after the Czech powered into the last four with a straight-sets win against Juan Monaco in the Miami Open quarter-finals.

Eighth seed Berdych defeated Argentine Monaco 6-3, 6-4 to ensure a first meeting with Murray since their tense and at times acrimonious Australian Open semi-final which Murray won in four sets.

Berdych and Monaco traded breaks early in the first set, but the World No. 9 would earn the pivotal break for a 5-3 lead. The 29-year-old Czech went on to serve out the first set at love.

The second set was even-keeled for the first eight games before Berdych broke for a 5-4 lead. The Czech served out the 92-minute victory at love.

"He was playing really well," said Berdych. "I managed to find situations, to create opportunities, and I executed them. I'm really pleased with that.

"There were a couple of long, tough rallies. The conditions were not easy. So there were a couple of challenges I needed to face, but I managed them all and went through."

On his fiery meeting with Murray in Australia, the Czech said: 'What's positive for me is that I think [Murray] played a very good tournament [in Australia], very good tennis, and I managed to find a way to win a set. It's definitely going to be my goal to stick to the game plan and execute it.'

Berdych is coached by Murray's former assistant Dani Vallverdu and has recently started working with the Brit's former fitness trainer Jez Green.

Meanwhile in the womens draw in Miami World number one Serena Williams claimed a landmark 700th career victory after overcoming a second set wobble to defeat Sabine Lisicki in the quarter-finals.

The world number one, a 19-time grand slam champion, edged a first set tie-break against her 27th seeded opponent, who then took advantage of Williams' inconsistency to take the match to a decider.

Williams had uncharacteristically made 17 unforced errors in the second set alone but bounced back against the German in the third, opening up a 3-0 lead before triumphing 7-6 (7/4) 1-6 6-3.

She is the eighth woman in the Open era to reach 700 match wins - although she is still well behind the record holder Martina Navratilova, who claimed 1,442 career victories.

The 33-year-old American was presented with a cake following the match but admitted she was oblivious to her record.

"I had no idea," Williams said on the WTA Tour website. "I saw them bringing out a cake and I thought, 'Whose birthday is it today?' But I really had no idea about it, so I'm really excited right now."

Williams was less enthusiastic about her performance against Lisicki, adding: "Today wasn't my best day. I wasn't serving the way I normally serve or hitting the way I normally hit, so all I could do was just fight and try to give 200 per cent instead of 100 per cent."
