<table> </table> NEW YORK | Serena Williams has said that it&#8217;s been so long since she won a U.S. Open championship that she doesn&#8217;t remember lifting the trophy.</p><p>She will get a chance to jar her memory after beating Dinara Safina 6-3, 6-2 in the semifinals on Friday.</p><p>Williams, who was in her first U.S. Open semifinal since winning the tournament in 2002, survived having her serve broken in the first game and broke Safina a total of five times in the 1-hour, 28-minute match.</p><p>Like the other semifinal, where Jelena Jankovic defeated Elena Dementieva 6-4, 6-4, both players had trouble with the wind and had more unforced errors than winners. But Williams had 21 unforced errors to Safina&#8217;s 41.</p><p>Williams successfully tamed her shots because of the conditions.</p><p>&#8220;If it is so windy, I am not going to go for so many winners,&#8221; she said on court after the match.</p><p>But she did not tame her aggressiveness. Williams hit Safina with a shot in the chest at short range in the second set. She apologized to Safina after the match.</p><p>Williams is looking forward to playing against Jankovic. She has a 3-3 record against her.</p><p>&#8220;She is playing so well and she has nothing to lose, and so do I,&#8221; Williams said. &#8220;It is going to be a great match.&#8221;</p><p>It will be Williams&#8217; 12th Grand Slam final, and Jankovic&#8217;s first.</p><p><hr class="infobox-hr-separator" /> <div class="infobox"> <strong><span class="infobox-head">Hanna looms </span></strong><br /> In the not-too-distant future, there might be a retractable roof on Arthur Ashe Stadium, and organizers won&#8217;t have to worry about tropical storms like Hanna, which is expected to bring heavy rain and wind to the New York area today.</p><p> &#8220;It&#8217;s a matter of &#8216;when,&#8217; not &#8217;if,&#8217;&#8194;&#8221; a dome will be added to Arthur Ashe Stadium, said Arlen Kantarian, the U.S. Tennis Association&#8217;s CEO for professional tennis. &#8220;It&#8217;s the right next thing to do.&#8221;</p><p>The start of the men&#8217;s semifinals &#8212; No. 1 Rafael Nadal vs. No. 6 Andy Murray and No. 2 Roger Federer vs. No. 3 Novak Djokovic &#8212; has been moved up an hour today. Starting time is 10 a.m. Central time. The tournament also was preparing to delay the women&#8217;s final if needed.</p><p> If rain forces the postponement of both of the men&#8217;s semifinals and the women&#8217;s final, which is scheduled for 6 Central time tonight, those matches would be rescheduled for Sunday. If the men&#8217;s semifinals are completed, but the women&#8217;s final is not, then the tournament plans to play both championship matches Sunday. </p><p></div>
