Renowned swimming announcer and enthusiast Duncan Scott joins Peter Busch on Friday's special edition of The Morning Swim Show to discuss the highs and lows of the US Olympic Swimming Trials.

Michael Phelps, Ryan Lochte, Katie Hoff, Natalie Coughlin and Dara Torres are among the Olympians Scott and Busch talk about, mentioning Phelps' chances at a perfect gold-medal run, Lochte's chances to break into the winner's circle and the comeback story of Torres.

Scott believes the men's 400 free relay will be the most-anticipated race of the meet, saying the top three teams could all break the existing world record. On the women's side, Scott says Australia looks unstoppable in the 400 free and 400 medley relays, thanks to such swimmers as Libby Trickett and Cate Campbell.

Scott and Busch also talk about Brendan Hansen's fourth-place finish in the 200 breaststroke, with Scott suggesting that Hansen might have been in the early stages of an illness.
