OMAHA, Neb. | Michael Phelps completed what he called a &#8220;pretty decent&#8221; week by winning five of his six events and qualifying in all eight of his events for the Olympics.</p><p>Phelps said he was disappointed Saturday night with his time in the 100-meter butterfly, which he won by nearly a second over runner-up Ian Crocker.</p><p>&#8220;I knew about two or three strokes out that I wasn&#8217;t going to have the finish that I wanted,&#8221; he said. &#8220;I knew as soon as I picked the last stroke, that wasn&#8217;t the finish that I wanted. There are a few little things that I can work on between now and the Olympics.&#8221;</p><p>Phelps said his turns and finishes must improve if he is to fulfill his goal of breaking Mark Spitz&#8217;s 36-year-old record of seven gold medals. Phelps was about 0.5 seconds off the world record time, set by Crocker in July 2005.</p><p>&#8220;This week turned out how I wanted it to,&#8221; Phelps said. &#8220;I&#8217;m excited. I&#8217;m ready for the challenge that lies ahead of me.&#8221;</p><p>Crocker qualified for the Olympic team with his second-place finish. It was his only chance after a slip-up earlier in the week; he was disqualified for a false start in the 100-meter freestyle preliminaries.</p><p><strong><span class="subhead">Hall motivated by Torres</span></strong></p><p>The league of aging swimmers lost a member from this year&#8217;s Olympic team when 33-year-old Gary Hall failed to qualify Saturday in the 50-meter freestyle. Hall finished fourth, nearly a half-second behind winner Garrett Weber-Gale.</p><p>The flamboyant Hall, who has won five gold medals in three Olympics, was the oldest male swimmer in last week&#8217;s meet. He said that after watching 41-year-old Dara Torres win the 100-meter freestyle on Friday &#8212; and qualify for the U.S. team &#8212; he thought that his career might not be over either.</p><p>&#8220;It&#8217;s definitely expanded the horizon of possibilities,&#8221; he said. &#8220;I&#8217;m not saying I will do this. I&#8217;m looking forward to getting back and spending some time with my family now.&#8221;</p><p>Torres had the best time in the 50-meter freestyle semifinals Saturday. She will be the top seed in tonight&#8217;s final and will try to qualify in her second event.</p><p><strong><span class="subhead">Bollier comes up short</span></strong></p><p>Mission Hills&#8217; Bobby Bollier finished sixth in the 100-meter butterfly, 1.8 seconds behind Phelps.</p><p>The 18-year-old Kansas City Blazers swimmer failed to qualify in any of his three events last week but said he was not discouraged.</p><p>&#8220;I&#8217;m pretty happy,&#8221; he said.</p><p><strong><span class="subhead">Another world record</span></strong></p><p>Margaret Hoelzer got a great surge off the wall heading into her third lap in the 200 backstroke then closed strong to finish in 2:06.09, beating the record of 2:06.39.
