PROBLEM: Roger Federer dominated Andy Murray on Tuesday at the ATP World Tour Finals and stretched his record to 2-0 at the season-ending event by winning 6-4  6-2.
 Federer looked unstoppable on the court at the O2 Arena  losing only eight points on his serve in the match -- three in the first set and five in the second.
 "He came out and made some mistakes. Maybe it was due to my good play " Federer said of Murray  who made 26 unforced errors. "I played tough and solid from start to finish. That seemed to be enough today."
 Later Tuesday  Robin Soderling was to face David Ferrer in the other Group B match. Federer can advance to the semifinals depending on the late result.
 Federer has won the season-ending event for the top eight players in the world four times  and he can certainly add to that if he keeps playing like he did Tuesday.
 Murray  however  dropped to 1-1 and will have to improve if he is to reach the semifinals. He will face Ferrer in his final match Thursday while Soderling takes on Federer.
 final match Thursday while Soderling takes on Federer.
 Murray struggled from the start Tuesday  forced to save a break point in the opening game. And it was his serve that was letting him down most of the way  landing only 44 percent of the first serves. That allowed Federer to take advantage of the much slower second serve.
 Federer earned his first break in the third game of the first set  winning all four points played. He then won his next three service games at love.
 In the second set  Murray saved two break points in the opening game  but Federer stayed alive through four deuces to earn a third break point  which he converted with a forehand that hit the top of the tape and zipped past Murray.
 After holding at love yet again  Federer broke again to make it 3-0 and soon led 4-0.
 "I tried to play quite aggressive. You're not going to hit winners every single time you go on the court " said Murray  who is 8-6 overall against Federer. "Today I made more mistakes than normal."

SOLUTION: No. 2 Federer beats Murray in 2 sets at ATP finals

PROBLEM: In late March   Timothy Nguyen   a 25-year-old coach at Quicksilver  a USA Swimming-affiliated club in San Jose  quit after an underage swimmer told the clubâs head coach that  Nguyen  had sent her suggestive messages through social media. The head coach informed USA Swimming officials  but no one told law enforcement.
Two months later  on May 30  Elizabeth Hoendervoogt  a USA Swimming official and abuse prevention specialist  called San Jose police to report  Nguyen  and send over messages the coach had exchanged with three swimmers  all aged 14 to 16.
In one exchange  police allege   Nguyen  asked a girl if sheâd been sexually active yet  discussed the specifics of several sex acts and then suggested they could be âfriends with benefits.â In another  police say   Nguyen  asked a girl for nude photos. One girl told police she had improved as a swimmer under Nguyen  and she had been concerned  he  would stop coaching her if she didnât respond.
In late June  police arrested  Nguyen . Then they learned Quicksilverâs head coach and USA Swimming officials had known about some of Nguyenâs behavior in March. In California  coaches are mandatory reporters and must inform authorities within 36 hours of learning of suspected sex crimes involving children.
USA Swimming spokesman Matthew Farrell said it took two months for the Olympic sports organization to report  Nguyen  to police because it took time to collect the text messages. When asked whether USA Swimming or the club should have handled the report differently  Farrell replied: âIâm not aware of any substantive changes that USA Swimming or the club would make.â

SOLUTION: Sex abuse in Olympic sports is not a new problem. Why does it keep happening?

San Francisco 49ers players  Reuben Foster  and Ray-Ray Armstrong were among victims in an attempted armed robbery Monday  a San Francisco Police Department spokesperson confirmed to USA TODAY Sports.
Since the investigation is active  the department cannot release full details of the report or names of the victims. However  the SFPD provided a synopsis of an attempted robbery that matched one that  Foster  and the 49ers organization acknowledged earlier this week following an initial report in Mission Local.
âWe are aware of the reports regarding the robbery and are very thankful no one was harmed â the 49ers said in a statement earlier this week. â Reuben  and Ray-Ray have been  and will continue to be  cooperative with any further police investigation.â
The incident took place Monday around 2 a.m.  according to police  and also involved two other victims who accompanied individuals believed to be  Foster  and Armstrong (Mission Local reported one of the victims was a security guard).
"We're safe "  Foster  told reporters earlier this week of the incident. "I'm blessed to be safe. ...I don't want to get in no detail  I'm just happy me and Ray and the rest of the people are safe.
