MELBOURNE, Australia - Friends off the court — Serena Williams and Caroline Wozniacki — face tough tests on Thursday when they play unseeded but potentially dangerous players in the second round at the Australian Open.No. 1-ranked Williams, attempting to win her sixth Australian Open title and 19th major, takes on former No. 2-ranked Vera Zvonareva in a day match on Rod Laver Arena day. Wozniacki plays two-time former Australian titleholder Victoria Azarenka in a night encounter on Margaret Court Arena.We have both pretty intense second-round matches, players who have been to the finals and one who has won Grand Slams, Williams says. Its going to be tricky for her and for me as well just to stay focused.Here are some things to watch on Thursday:___HOLDING THE EDGE: Despite winning seven of her nine matches against Zvonareva, Williams is aware of how good a player the 30-year-old Russian was in 2010 when she made it to the Wimbledon and U.S. Open finals and rose to No. 2 in the rankings. That was before a right shoulder injury and subsequent surgery forced Zvonareva off the tour for more than a year. Zvonarevas official ranking now is 203. Its going to be tough, she does so many things well, Williams says. Shes on the way back. I know shes been fighting and playing really hard.___DJOKOVIC, NISHIKORI RETURN: Two players in the top half of the mens draw who could meet in the semifinals — top-seeded and four-time champion Novak Djokovic and U.S. Open runner-up Kei Nishikori — are in action in the second round. Two men who could upset that scenario — Canadian Milos Raonic and defending champion Stan Wawrinka — are also playing Thursday. Djokovic plays Andrey Kuznetsov of Russia and Nishikori takes on Ivan Dodig of Croatia. Eighth-seeded Raonic, in Djokovics quarter of the draw, takes on American Donald Young, while Wawrinka, who could meet Nishikori in the quarterfinals, is up against Marius Copil of Romania.___ANOTHER TOUGH ONE: Wozniacki leads Azarenka 4-3 in their seven meetings. Wozniacki won four in a row before Azarenka, the 2012 and 2013 Australian Open champion, beat Wozniacki in their last meeting at Cincinnati in 2013. Not the easiest on paper (but) honestly, whether you have to beat her in the second round or fourth round, whatever, doesnt matter if you want to win the tournament, says Wozniacki. Azarenka, whose ranking slipped late last year after foot and knee injuries restricted her to just nine tournaments, said shes just happy to be here: Thats my key word for this tournament: Compete.___JUNIOR MEMORIES: Raonics match against Young, the 25-year-old American, brings up a lot of recollections for his opponent from north of the border. A former No. 1-ranked junior and once featured in a weekly newsmagazine article entitled Whos Next? Young was touted to be the next big American player when he began playing professionally at age 15. Hes never quite achieved that potential. He was sort of the poster boy of the way everybody sort of wanted their junior career to go, says Raonic. I definitely followed because there were a lot of tags and labels on him, (I) was aware of sort of what happened, then what he went through. Theres always been a big spotlight on him. Raonic, 24, didnt have a stellar junior career — never getting past the second round of any junior Grand Slam tournament — but hes blossomed into a bona fide top-10 player and considered to have Grand Slam championship potential.__Follow Dennis Passa on Twitter: http://twitter.com/DennisPassaJosh Allen Womens Jersey .

The move is retroactive to Saturday. Harper hurt his hand with a head-first slide into third base Friday night after hitting a third-inning, bases-loaded triple in Washingtons 11-1 victory. He stayed in the game for an inning before he was replaced. "Its part of baseball. You slide into the bag and sometimes you get your fingers," Harper said. "Its a bummer, but hopefully Ill be back soon." Harper will fly to Cleveland on Monday to see prominent hand specialist Thomas Graham for a second opinion. For now, his proscribed treatment is ice. "Hopefully 15 days go by and I can get back out there," Harper said. "Well see how I feel in 15." Harper joins starting catcher Wilson Ramos and starting thirrd baseman Ryan Zimmerman on the disabled list, both with hand injuries.ddddddddddddRamos, hurt on opening day, had surgery on his left hand. Zimmerman broke his right thumb also sliding into a bag, on April 12. Also on the DL are starting pitcher Doug Fister (back), who is scheduled for a rehab start on Sunday, and reserve outfielder Scott Hairston (side). "Weve got a lot of off days in the next 15, so thats huge," Harper said. Harper went 2 for 2 and had a career-high four RBIs on Friday night, giving him nine for the season as he lifted his batting average to .289. He has only one home run in 83 at-bats. "Its frustrating," Harper said. "I want to be out there and be able to help my team win every single day." Steven Souza Jr. was recalled from Triple-A Syracuse to replace him on the roster but was not in the lineup Sunday. ' ' '
