Q: And with a mangled racket and plenty of kicking and screaming  including a couple of arguments with the chair umpire  then a postmatch parting shot at a line judge Safin called "a little bit too blind."
 Safin used to rant about disliking tennis on grass  and he once complained about the high price and low quality of food at the players' restaurant at the All England Club. Well  he doesn't have to worry about any of that again after bowing out in his final Wimbledon with a 6-2  3-6  7-6 (4)  6-4 loss to Levine.
 After confirming this would be his last appearance at the grass-court Grand Slam tournament -- Safin has vowed to retire at season's end -- he was asked how he feels about being done with Wimbledon.
 He's a former No. 1 player who won the 2000 U.S. Open and 2005 Australian Open  but a series of injuries slowed him recently. Still  Safin came to Wimbledon ranked 24th and seeded 14th  and had to be considered quite a favorite against Levine  who never had defeated anyone ranked better than 67th.

 He's a former No. 1 player who won the 2000 U.S. Open and 2005 Australian Open  but a series of injuries slowed him recently. Still  Safin came to Wimbledon ranked 24th and seeded 14th  and had to be considered quite a favorite against Levine  who never had defeated anyone ranked better than 67th.
 "He's an amazing player  and I'm still kind of feeling weird right now that I just beat Safin  because I've always watched him play on TV " said Levine  who turned pro in 2007. "I just kind of went out there with nothing to lose and played some good tennis."
 Levine was a teen when Safin burst onto the scene as a brash  big-hitting 20-year-old who knocked off Sampras to win the U.S. Open.
 "I really had to ... focus on playing against the ball and not worrying about  'Oh  wow  I'm playing against Marat Safin on the other side of the court '" Levine said. "Because then things could have gotten a lot more interesting."
 As is his wont  Safin made things interesting enough. In the early going  he broke his racket by spiking it on the court.
 Leading 4-3 in the third-set tiebreaker  Safin hit a shot near a line that was ruled out. Afterward  Safin said: "Thanks for the guy who made the call. I want to say hello to him. Too bad that he was a little bit too blind."
 In the fourth set  Safin told the chair umpire he could check for chalk on the ball to confirm a call. Rebuffed  Safin added: "So all players are stupid?"
 Safin reached at least the semifinals at all four majors  including at Wimbledon last year  but he has been criticized for not living up to the potential stored in his 6-foot-4 (1.93-meter) frame -- about 7 inches (18 centimeters) taller than Levine.
 "In the history of tennis  everybody's an underachiever " Safin said. "Agassi should have been winning  I don't know  15 Grand Slams. Sampras should have been winning 20 Grand Slams. Federer should be winning -- already should have 25."
 "I should probably have (won) a couple of more " he said  "but I'm pretty satisfied with what I did."

Q: NAYPYITAW (Reuters) -  Pope Francis  on Tuesday urged the leaders of majority-Buddhist Myanmar  mired in a crisis over the fate of Muslim Rohingya people  to commit themselves to justice  human rights and respect for âeach ethnic group and its identityâ.

 The pope  avoided a diplomatic backlash by not using the highly charged term âRohingyaâ in  his  addresses to officials  including leader Aung San Suu Kyi.
However   his  words were applicable to members of the beleaguered minority  who Myanmar does not recognize as citizens or as members of a distinct ethnic group.
More than 620 000 Rohingya have fled to Bangladesh - where  the pope  heads on Thursday - since the end of August  escaping from a military crackdown that Washington has said included âhorrendous atrocitiesâ aimed at âethnic cleansingâ.
 Francis  made  his  comments in Naypyitaw  the countryâs capital  where  he  was received by Suu Kyi  the Nobel peace laureate and champion of democracy who has faced international criticism for expressing doubts about the reports of rights abuses against the Rohingya and failing to condemn the military.

Referring to the countryâs communal tensions   Francis  said religious differences âneed not be a source of division and distrust  but rather a force for unity  forgiveness  tolerance and wise nation-buildingâ.
Only about 700 000 of Myanmarâs 51 million people are Roman Catholic. Thousands of them have traveled from far and wide to see him and more than 150 000 people have registered for a mass that  Francis  will say in Yangon on Wednesday.
 Francis  is expected to meet a group of Rohingya refugees in Dhaka  the capital of Bangladesh  on the second leg of  his  trip.
