Roger Federer worked a kid's clinic indoors in the afternoon and was more than generous with his time and also had a lot of fun with the kids, a worker at the clinic told me. Federer could have showed up and waved hello and said goodbye in a couple of minutes and everybody would have been happy. But Federer stayed for an hour and twenty minutes. Everyone was beyond thrilled. They're still not done constructing the new two-tier Hieneken bar lounge arena near the practice courts. And it looks like they have a long way to go.Rhyne Williams beat Golubev, who was playing ATP events earlier in the year. Jack Sock, last year's mixed doubles champ with Melanie Oudin, came by to show support.Murray practiced with Monaco on Armstrong. Lopez was with Ferrer.I saw some of Mitchell Krueger, the highly touted 18-year-old American, lose a close one to South African veteran Rik De Voest 6-4 in the third. In the third set something happened that I've never seen before. Krueger was serving at deuce and on two consecutive points his shot hit the line and was called out by the linesperson but then instantly overruled by the chair umpire. Krueger was livid by contained it well. He would eventually lose the game. I was able to do a Biofile with De Voest moments after the big win.Tobias Kamke was hitting on the practice court right in front of the Heineken construction site and exactly three people were watching. He looked sharp too but nobody knew who he was. The last match of the night ended just before ten on court 17 with Paula Ormaechea besting Madison Keys in two sets 64 62. Lukas Rosol lost some fans today after his win in straight sets over Colombia's Alejandro Gonzalez on court seven, he ducked the huge throng waiting for photos and signatures by running over to the side exit. Still, some astute fans caught up to him over there and had their photo and autograph requests rebuffed. Rosol ran out of there with a towel over his head as disguise. Fans were not too happy with the superstar treatment, especially when guys like Djokovic and Nadal are incredibly generous with their time for fans. I will never forget Nadal signing everything for everyone after an Armstrong practice last year and then hopping the barrier and climbing into the stands - without security - to leave the court that way. On his way through the crowd, Nadal signed some more and took more photos with fans. Unbelievable.Spoke with Guillermo Canas for a minute about his two wins in 2007 over Federer by court seven. While we spoke, his new player that he coaches Teymuraz Gabashvili, on his way back the locker room after beating Simon Gruel 7-5 in the third on court eight, was super intense, sweaty and smiled scowled a muffled VAMOS!! to Canas. It was cool to see the facial expression of such fire and passion in a pro player after a big win. Canas is just coaching Gabashvili for this week but by that positive interaction look for the two to stay together longer. Canas, looking jacked up and muscular, operates an academy in Key Biscayne.Marco Trungelliti of Argentina was playing American lefty Bradley Klahn in a bright pink shirt. Far more eye-catching than that one Dominik Hrbaty wore about eight years ago.Dustin Brown lost to Tim Smyczek 64 64.A couple of upsets for young American prospects - Laruen Davis lost to Julia Glushko and Krista Hardebeck fell to Tatjana Malek. Grigor Dimitrov was supporting his buddy and sometimes doubles partner Dimitry Tursunov who beat Rochette of France. Tursunov, ever the clown, was communicating and making faces at Dimitrov while on court. Remember Elena Bovina? The tall pretty Russian is still around the pro tour but she lost to another Russian.Oddest sight of the day: I saw a Filippino fan named Miranda sporting a custom made white shirt with the Ashley Harkleroad Playboy Magazine cover on the back. A player to watch: 16-year old Croatian Donna Vekic defeated the #7 seeded Karolina Pliskova.[caption id="attachment_6361" align="alignright" width="222"] Rosol[/caption][caption id="attachment_6362" align="alignright" width="259"] Miranda with his Harkleroad shirt[/caption][caption id="attachment_6363" align="alignright" width="207"] Dustin Brown[/caption]
