Three Stars: Day 6

WIMBLEDON, England — A look at three individuals who distinguished themselves as Wimbledon's first week came to a close:

1. Bernard Tomic. Just when Robin Soderling looked like a major threat, coming from two sets down to defeat the feisty Lleyton Hewitt, here came the 18-year-old Tomic, perhaps annnouncing his arrival as a big-time threat Saturday with a 6-1, 6-4, 7-5 win over fifth-ranked Robin Soderling. Tomic is certainly no mystery in the tennis world. At 16, he became the youngest man ever to win a match at the Australian Open (his homeland, although he was born in Germany to Croatian parents). He has a funky service motion and loves to shift strategy in mid-match, saying, "My strength is that I can find players' weaknesses really quickly. That's what I've always been good at." He found Soderling's early on, and never let up.

2. Mardy Fish. It was a somewhat unsatisfying victory, Robin Haase retiring with an injury in the fourth set, but Fish could use a break: he's carrying the hopes of American men's tennis by himself these days. He was the only U.S. man to reach the third round at Roland Garros, and now he's flying solo into Wimbledon's fourth round. "I appreciate things so much more now," Fish said of his career resurrection, launched last year thanks to hard work and a strict diet. "When I was 22 and played in the (2004) Davis Cup final, I had no understanding of where I was at. The years went on, and I was like one of those rookies who wins the Super Bowl in his first year, and thinks it's easy, and he never goes back. I feel like I'm maximizing my talent now. I sleep a lot better than I used to, just knowing I'm doing everything I can to reach my career goals."

3. Venus Williams.
