THERE were no slip-ups from Andy Murray at SW19 yesterday - on a day when safety of the players due to moisture on the famous grass courts emerged as a talking point. The Scot continued his sure-footed progress at this year's Wimbledon with a 6-3, 6-2, 6-1 win against Yen Hsun-Lu of Taipei. He will now face John Millman, the World No 67 from Brisbane, Australia, in tomorrow's third round.

Lu, a player with recent grass court pedigree and still the only man to beat Andy on Olympics singles duty, back in Beijing in 2008, inflicted the first service break of the 29-year-old's tournament as he raced into a shock 3-1 first set lead. But he was permitted just three further games thereafter.

In all, the Scot was detained only 100 minutes, meaning that through the first two rounds of this tournament he has already been on court for 45 fewer minutes than his great rival Novak Djokovic. His fortunes weren't shared by the No 2 seed in the women's draw, last year's runner-up and reigning French Open champion Garbine Muguruza, who was a shock straight sets loser to Jana Cepelova of Slovakia.

"The first set, you know, was a tough set," said Murray. "Once I got that, and an early break in the second, I started to settle down, and played better tennis. This was an improvement from the first round, against a guy who has won a lot of matches on the grass recently. I was just happy I improved as the match went on. Hopefully I start the next match like I finished this one."

Gilles Simon, a four-set loser to Grigor Dimitrov, said yesterday that he felt desperate tournament organisers have been taking chances with players' safety on damp courts and said he would take the matter up at the ATP players' council, on which Murray has a seat. Further showers are forecast at SW19 today, and the Frenchman's mood perhaps wasn't helped by the fact a supervisor told him that, while it was raining, the ground wasn't getting wet. "If I'm going to get injured on slippery grass," Simon said. "I'm going to sue everyone in the stadium."

Murray supported the general principle, but for the second round running wasn't adversely affected by any of it. Once again he managed to get his work done before any serious rain fell. "What you don't want to have happen is for a player to really hurt themselves," he said. "On a grass court, when it's raining, it becomes dangerous very quickly. There just needs to be a little bit of balance and common sense sometimes. So maybe that's something we'll discuss and try and change.

"It was at 4?1 in the third when I got up to serve and there were a few raindrops," he added. "But I wasn't worried so much about the court being wet. I obviously wanted to try to get the match done, if I could, before it started raining."

Having met Millman - a man who has battled career-threatening injuries - in competitive action just once, on his home terrain of Brisbane, now the World No 2 has the home advantage on one of the most famous courts in the world. "I didn't know him before we played in Brisbane," said Murray. "I knew it was his hometown and he played extremely well that day. He was ranked about 200 at the time. But I came off the court and I said to Dani Vallverdu, who I was working with, that he's top 50 for sure if he keeps going."

While the exits of Heather Watson and Johanna Konta meant Tara Moore was the only Brit still standing in the women's singles, Murray still has a countryman for company in the Wimbledon third round, where after the Marcus Willis experience on Wednesday night, Dan Evans is the latest British player slated to take on Roger Federer on Centre Court. The 26-year-old from Birmingham, a boyhood pal of Willis from the Midlands tennis scene, said that he would be sure not to ask his friend for advice as he isn't just going into the match to make up the numbers. "It's not a day out for me, to be honest with you," said Evans, who impressively took care of the No 30 seed Alexander Dolgopolov of Ukraine yesterday by a 7-6 (6), 6-4, 6-1 scoreline. "It's a chance, a good opportunity. It's not the Lord Mayor's show or whatever. I'm taking it seriously."

Muguruza's early exit was also no laughing matter. The Spaniard, so imperious at Roland Garros was out 6-3, 6-2 in less than an hour to her Slovak opponent. "I think my energy was missing a little bit today," she said. Dominic Thiem and David Ferrer were two high-profile fallers in the men's draw, while Viktor Troicki went down fighting. The Serb faces disciplinary action after exchanging angry words with an umpire.
