OMAHA, Neb. -- Ryan Lochte and Michael Phelps stayed on course for their second showdown at the U.S. Olympic swimming trials on Tuesday. Janet Evans' first appearance in the meet was brief, with the 40-year-old former Olympic champion failing to advance to the 400 freestyle final.

Lochte qualified fastest in the 200-meter freestyle preliminaries, exploding off the final turn to take the lead and cruise into the wall at 1 minute, 48.14 seconds. He's the world champion in the event, having beaten Phelps for the title last year in Shanghai.

Charlie Houchin, a 24-year-old from Raleigh, N.C., who was 77th in the 200 free at the 2008 trials, was second-fastest at 1:48.15. Swimming in the heat before Lochte, Phelps qualified third at 1:48.31. He is the Olympic champion and world record holder.

Evans finished seventh in her heat at 4:21.49 -- 6.81 seconds behind 19-year-old winner Danielle Siverling. But Evans, who won the 400 free as one of her three golds at the 1988 Olympics, was merely using the event as a warm-up for the 800 free. She is a long shot in that grueling event after a 15-year absence from the sport.

Budding star Missy Franklin and two-time Olympic champion Natalie Coughlin advanced in the 100 backstroke prelims.

Lochte got the better of Phelps in their first final at trials when he won the 400 individual medley on Monday. Phelps finished second, and they both secured spots for London.

Phelps has set himself up for another eight-event program in London -- something he insisted he wouldn't do again after the Beijing Games.

"It's not an easy program, but we're going to try to do some things here," he said. "The biggest thing is really how I hold up all week. I was definitely happy with getting last night out of the way early. It wasn't the easiest race. But this morning felt pretty comfortable, so hopefully we can just keep everything rolling for the rest of the meet."

Can Phelps repeat his historic haul of eight golds?

"Anything can happen," he said. "You've got to be in the right place at the right time."

After swimming the second-fastest qualifying time in the 100-meter backstroke on Tuesday morning, Lochte and his coach Gregg Troy decided to scratch for Tuesday night's semifinals. That decision means that Lochte will likely swim in six events in London, the same number he competed in at last year's World Championships in Shanghai.

"He really wants to swim the 100 and we were kind of happy this morning," Troy said, "but looking at the program as it goes through the weeks and looking at the Olympics where there's going to be even less time ... this isn't about how many we can swim but how many we can swim well."

Keeping the 100 back would have likely added the 4x100 medley relay as well, putting Lochte in line for eight events and at least giving him a chance to tie Phelps' record eight gold medals from Beijing. Now it appears that won't happen. Barring something unforeseen during trials this week in Omaha, Lochte will swim in the 200 IM, 200 free, 200 back and two relays at the Games. He qualified in the 400 IM on Monday night.

Lochte is also entered in the 100 butterfly, 100 breaststroke and 50 freestyle here this week but most believe he won't swim those events this week or if he does in London.

On Tuesday morning, his time of :53.92 was the second fastest in the 100 back and his time of 1:48.14 was the fastest in preliminaries for the 200 freestyle.

"It wasn't that bad of a double," Lochte said. "The 100 back hurt worse than the two free. The two free was really just smooth, just trying to get a lane for tonight."

Swimming in the previous 200 free heat before Lochte, Phelps swam a 1:48.31, seeding him third for the semifinals.

Also moving into the 16-man evening semifinals were Conor Dwyer (fifth) and Peter Vanderkaay (sixth). They already earned berths on the U.S. team in the 400 freestyle Monday night.

Davis Tarwater, who narrowly missed making the 2008 Olympics when he was third in the 200 butterfly, was eighth. Ricky Berens, bidding for his second straight Olympic spot, was ninth.

In the women's 400 free, Katie Hoff joined Evans on the sideline after finishing 20th in 4:13.08. Hoff won the event four years ago at trials -- one of her five victories that had her dubbed the female Phelps. Her coach, Paul Yetter, said she was feeling sick from something she ate.

Hoff has just the 200 free remaining to try to make her third straight Olympic team.

"I hope she'll be able to get herself eating today and feeling better," Yetter said. "I've never seen her look that white."

Allison Schmitt was the top qualifier in the 400 free at 4:05.60. Katie Ledecky, a 15-year-old from Bethesda, Md., was second at 4:05.78. Also advancing to Sunday's final were Chloe Sutton, Elizabeth Beisel and Kate Ziegler.

Swimming her first event of the eight-day meet, Franklin was the top qualifier in 59.54 seconds, easily moving the 17-year-old from Colorado into the evening semifinals.

"I had some first-race jitters," she said. "But I'm super, super happy with my time. It felt awesome."

Franklin saw the sign under the massive scoreboard above the pool as she stroked to the opposite end of the pool.

"It was U.S. Olympic Team. Talk about motivation. That helped me get my tempo up the last 25," she said. "I was nervous for my first race. But right now, I feel good."

Franklin led a quartet of teenagers who represent the U.S. future in the event. Rachel Bootsma, an 18-year-old from Minnesota, was second at 59.69, making her and Franklin the only women to go under 1 minute.

Elizabeth Pelton, an 18-year-old from Connecticut, was third at 1:00.55. Olivia Smoliga, a 17-year-old from suburban Chicago, was fourth-quickest at 1:00.66.

Coughlin advanced in fifth at 1:00.71. She was the first woman to break 1 minute in the event and formerly held the world record.

The top 16 in the semifinals move on to Wednesday's final, where only the top two earn berths for next month's Olympics.

World champion Rebecca Soni led the way in the 100 breaststroke, coming on strongly over the final 50 meters to win her prelim heat in 1:06.33.

Breeja Larson showed no nerves in her first Olympic trials, turning in the third-fastest time in the world this year to qualify second-quickest at 1:06.52. The sophomore at Texas A&M didn't start swimming competitively until age 17 in her hometown of Mesa, Ariz.

Jessica Hardy, who won the 100 breast at trials four years ago only to lose her spot on the Olympic team because of a failed doping test, was third at 1:07.25. Hardy served a one-year ban after an arbitration panel agreed with her contention that a tainted nutritional supplement was to blame for her positive test.

Still, she battled anger and depression during the fight to clear her name.

"This is the first time I felt like I can actually have a happy ending," she said. "I can relax and finally have fun and feel grateful."

Soni caught Hardy's time as she was waiting to come on deck.

"She did really well. It gets you kind of pumped up," she said. "The times are getting faster and faster every year. I definitely have to keep my 'A' game going."

Amanda Beard, the 1996 Olympic silver medalist in the 100 breast, qualified seventh for the evening semifinals. The 30-year-old mother of one is trying to make her fifth Olympic team, but the 100 is not her best event and she will have to pick up the pace to make the eight-woman final.

"I think my chances are great," she said. "But this isn't my life. My life doesn't just revolve around swimming. I won't be too devastated walking away and saying I competed at my fifth Olympic trials. I'll look at it as a success and go on a nice vacation with my family."
