SINGAPORE - After Serena Williams embarrassing defeat to Simona Halep in the WTA Finals group stage, the American narrowed her eyes at the post-match news conference and said she was looking forward to having a chance to avenge the loss.She didnt have to wait long. The pair will face off again on Sunday in the final of the season-ending championships after winning their semifinals on Saturday in contrasting fashion.Williams beat Caroline Wozniacki in a thrilling contest 2-6, 6-3, 7-6 (6) to remain on course for a third-straight title, while Halep swept aside Agnieszka Radwanska 6-2, 6-2 to put herself in a position for the biggest title of her career.Halep beat Williams 6-0, 6-2 in the group stage, inflicting the Americans heaviest loss in 16 years, and the 18-time Grand Slam winner joked about her diminished expectations for the re-match.My goal is to win three games, Williams said. Im going to go from there. Hopefully I can hold serve — that would be good. Most of all, I hope to break once.Halep has been the form player of the tournament, dropping only 27 games across four matches against top-eight-ranked opponents, and the Romanian was justifiably confident entering Sundays final.I have to believe in my chances against her, the French Open finalist said. I can think that I have the game to beat her.I will be nervous because its the final, but I cant wait for tomorrow because my dream came true, so I have to do everything I can to win.The irony of Sundays final is that Williams only qualified for the semis because Halep lost in three sets rather than two in her final group match against Ana Ivanovic. Had the already-qualified Halep eased off and lost in straight sets, Williams would have been packing her bags.The Americans hopes of reaching the final looked just as tenuous throughout Saturdays clash with Wozniacki.The Danish player served for the match at 5-4 in the third set, but Williams broke back and prevailed in the tiebreaker on her third match point after trailing 4-1.It was a bittersweet win for Williams, who has developed a close off-court friendship with Wozniacki. The pair attended a Mariah Carey concert together on the eve of their semifinal.It was the first match I didnt feel great — if you take (sister) Venus out of the equation — where I wasnt happy after I won, Williams said.I really wanted to cry because Caro is so nice. We get along and we do so much together. Shes like my little baby sister, from a different mother, and father, and different country.Wozniacki reciprocated the affection, but being on the wrong end of a 10-1 head-to-head record meant she understandably wanted to see less of the world No. 1.I told Serena Can you just leave me alone? I love you, but stay away from the other side of the court. Quite frankly Im sick of losing to you, Wozniacki said.Twice before this year Williams had to come back from a set down to beat the Dane and she again made a slow start, taking only three points off Wozniackis serve in the opening set and the frustration showed. After the seventh game, she repeatedly smashed her racket into the court, bringing a warning from the chair umpire.I dont know how many times I hit it but, boy, that racket will never do me wrong again I tell you, Williams said. It was definitely legendary. I kind of lost my cool a little bit.Wozniacki, who had a perfect 3-0 record in the group stage, took the opening set in 26 minutes and held serve to open the second.I really thought she was going to win because she was playing so well, Williams said. She had a whole new strategy. I finally was able to kind of figure it out in the second and then I just was able to play better.It clicked today. I thought Ha! I got you now.The momentum had shifted and, three games later, Williams created her first break points of the match, converting to take a grip on the set, which ended on Wozniackis double fault.The third set went on serve until the ninth game when Wozniacki made the first break. She served for the match but was only able to save one of two set points.Williams survived a break point on her serve to go up 6-5. Wozniacki then held serve under intense pressure in the 12th game, saving one match point in a dramatic rally.She started the tiebreaker confidently, but the relentless Williams wore her down with powerful serves and groundstrokes.Being so close and still losing, it really (stinks), Wozniacki said. It was just small things, but that is why champions are champions. All of them step up when it matters. Adam Henrique Jersey .

Got a question on rule clarification, comments on rule enforcements or some memorable NHL stories? Kerry wants to answer your emails at cmonref@tsn.ca. Hi Kerry, Im in the middle of watching the Oilers-Predators game Tuesday night where we saw a puck that entered the net called no goal by the ref behind the net. After over a minute of continued play which included an Oilers penalty, the play finally stopped and the refs were able to review the goal (it was a good goal). The broadcasters said that they would have to bring the play back to the moment in time when that goal happened, so I was surprised to see Mark Frasers penalty stand from the end of the play. My question is as follows: What would have happened if Nashville had scored a goal as well? They had some good sustained pressure after the Hall goal. They let the penalty at the end of the play stand, but would they have also let a Nashville goal stand? Thanks. Aaron Deblois,Edmonton Aaron, Once video review was instituted to determine the scoring of legitimate goals, including those that are undetected by the referee during the course of play, Rule 78.6 was included in the rule book to cover the situation that occurred in Tuesday nights Oilers-Predators game. Interestingly, I was called to rule upon the identical situation the first very time it occurred in an NHL game. Current executive VP and director of hockey operations Colin Campbell was behind the bench that night as coach of the NY Rangers for a game in Pittsburgh. The Rangers scored an undetected goal and play continued for another minute until I blew my whistle for a Ranger penalty. While assessing the penalty, a horn sounded to signify the play was placed under review by the video goal judge located in the Pittsburgh Arena. Video review confirmed that the puck had indeed entered the net for a Ranger goal. I instructed the timekeeper to re-set the clock to the time of the goal and place two minutes on the Rangers penalty clock. I explained the strange turn of events that resulted from this new rule application to Coach Campbell at the Rangers bench. While pleased with the award of a goal for his team, the coach was somewhat miffed that the penalty should stand given the difference inn game time that had occurred.dddddddddddd Nonetheless, Campbell trusted my knowledge of the rule and the Rangers killed off the minor penalty. This initial situation was handled "on-site" by the referee and the video goal judge. Currently all video decisions are made "off-site" in the Situation Room in Toronto under the direction of former coach, Colin Campbell who received some basic training that night in the Igloo. Aaron, I provide points from Rule 78.6 that address various scenarios and answer your specific question. • Any potential goal must be reviewed during the next stoppage of play. No review can take place after the puck has been dropped.• If an apparent goal is confirmed by video review, the clock is re-set to the time the goal was scored.• Only one goal can be awarded at any stoppage of play. Had Nashville subsequently scored to stop play after Taylor Halls undetected goal, the Preds goal would not stand.• If review determined that the undetected goal by Taylor Hall was scored illegally (i.e. distinct kicking motion), the goal shall be disallowed and since the play should have stopped, no subsequent goal scored by either team can be awarded on the same play. The clock (including penalty time clocks, if applicable) must be re-set to the time of the disallowed goal by Hall.• Any penalties (Mark Fraser) signaled during the period of time between the apparent goal (scored by Hall) and the next stoppage of play shall be assessed in the normal manner, except when a minor penalty is to be assessed to the team scored upon (Nashville), and is therefore nullified by the scoring of the goal. If the penalty to be assessed (Nashville) was a double minor, one of the minors would be nullified with the scoring of the goal.• *If an infraction happens after the first stoppage of play following an apparent goal (i.e. infraction committed by Mark Fraser or a Preds player occurred after the whistle) by either team, it is assessed and served in the normal manner regardless as to the decision rendered by the Video Goal Judge. Whenever this unusual play occurs in a game, Rule 78.6 provides the necessary check-list for the referee and video review to follow.
