It was a day of Bercy semifinal rematches here at the O2 Arena on day 2 as Djokovic resumed his rivalry with Federer and Nadal faced off against compatriot Ferrer just 3 days after they had previously clashed on Saturday. The top two ranked players prevailed over their opponents today in contrasting styles with Djokovic outlasting a spirited Federer 6-4, 6-7(2), 6-2 while Nadal made short work of a tired Ferrer 6-3, 6-2. Both doubles matches went the distance as first Paes & Stepanek beat Peya & Soares 6-3, 5-7, 10-8 and then championship debutantes Dodig & Melo stunned the top seeds, the Bryan brothers 3-6, 6-3, 10-8 in tense match tie-breaks.

No. 7-seeded American Victoria Duval was crowned champion of the 2013 Tevlin Challenger on Sunday after her opponent in the final, top-seeded Timea Babos of Hungary, was forced to retire due to respiratory illness at the start of the second set to give Duval the 7-5 ret. victory at the $50K ITF Pro Circuit event at Rexall Centre in Toronto.

Babos advanced into the final despite struggling with illness all week, and though it was evident versus Duval she was not feeling well, the 20-year-old kept the match close. Duval started strongly, breaking to start the contest before Babos evened up it up after six games to make it 3-3. Babos took a medical timeout after falling behind again 5-4, with the pair then exchanging breaks before Duval was able to serve out the first set. Babos then went down 0-30 on her serve to start the second set before being unable to continue.

Playing in his third career ATP semifinal, Vasek Pospisil came within a handful of points of defeating Roger Federer at the Swiss Indoors on Saturday, an ATP World Tour 500 event.

The legendary Swiss served for the match at 6-3, 5-3 only to see the 23-year-old Canadian start an improbable comeback that would allow him to win the second set 7-6(3) thanks to an impressive tiebreak. In the final set, Pospisil found himself up a break at 3-1 and he also held a break point on Federer’s serve at 4-3 that would have allowed him to serve for the match, but that is as close as he would get to pulling off the upset. Federer tightened up his game just in time to come away with a 6-3, 6-7(3), 7-5 victory to reach his tenth final at his home tournament.

Vasek Pospisil advanced to the third ATP semifinal of his career on Friday at the Swiss Indoors in Basel, Switzerland, an ATP World Tour 500 event.

Pospisil continued his strong play indoors with a 7-6(11), 6-4 win over world no. 29 Ivan Dodig of Croatia to book his spot in the semifinals. He saved multiple set points in the opening set tiebreak and was able to get the decisive break at 4-4 in the second set to come away with a straight sets win.

In Saturday’s semifinals, Pospisil will face Swiss Roger Federer. They played once previously in the second round of the Rogers Cup presented by National Bank in Montreal in 2011 and Federer won in straight sets. Federer won a tight two setter against Grigor Dimitrov of Bulgaria 6-3, 7-6 (2) to set up his semi-final clash with Pospisil.

Pospisil’s two previous ATP semifinal appearances came earlier this year in Bogota and at the Rogers Cup in Montreal.

The International Tennis Federation announced that the Court of Arbitration for Sport (“CAS”) has partially upheld the appeal by Marin Cilic against the decision of the independent tribunal dated 23 September 2013. The independent tribunal had determined that Cilic should be suspended from participation for a period of 9 months, commencing from 1 May 2013 (the date on which the sample containing the prohibited substance was collected) and so ending at midnight on 31 January 2014 for the commission of an Anti-Doping Rule Violation under Article C.1 of the Tennis Anti-Doping Programme (presence of a Prohibited Substance in player’s sample).

The CAS panel decided that the independent tribunal’s decision be set aside, and replaced with a period of ineligibility of four months, with the start back-dated to 26 June 2013, the date on which Mr Cilic accepted a voluntary provisional suspension. He thus will be eligible to participate on 26 October 2013.

Eugenie Bouchard came close to winning her first WTA title on Sunday, but ultimately fell 3-6, 7-5, 6-2 to Samantha Stosur of Australia at the HP Open, an International Series event in Osaka, Japan.

Bouchard started the match on the right foot, jumping out to a 6-3, 4-3 lead. On two occasions she was six points away from capturing her maiden title. Stosur, U.S. Open champion in 2011, broke Bouchard’s serve at 5-5 in the second set and never looked back en route to collecting her fifth career title and second this season.
