LOS ANGELES - Michael Phelps was pipped by training partner Chase Kalisz in the 200m butterfly at the Minneapolis Pro Swim meeting -- the second straight race that the Olympic superstar failed to top the podium.

Phelps led at the 100m mark with a split of 56.04sec, but Kalisz powered past him to win in 1:58.07 -- well outside the world-leading 1:52.94 Phelps clocked in winning the US title in San Antonio in August.
Phelps, aiming to add to his record 18 Olympic gold medals at the 2016 Rio Games, was second in 1:58.38.
Grant Shoults was third in 2:00.41.
While the defeat followed Phelps's third-place finish in the 100m fly on Thursday, it's no cause for alarm as he's racing this week in the midst of intensive training.
In other finals on Friday, Missy Franklin won the 100m backstroke in 1:00.18 to end a victory drought that had stretched back to the NCAA collegiate championships in March.
Franklin won three events in that meeting, but hadn't won since turning pro immediately after.
Franklin, who won four gold medals at the 2012 Olympics and six at the 2013 worlds, admitted this week that the slump -- which included just a silver and bronze to show for four events at this year's World Championships -- was demoralizing.
In her classic ebullient style she said this week she was embracing it as "an incredible growth experience" but the victory was clearly a relief.
"This was huge for me," Franklin said. "I am still dying to get into the four digits and was close with the 1:00.1, but most importantly getting a win under my belt for the first time in quite a while feels really, really good."
Freestyle phenomenon Katie Ledecky continued her smooth build-up to the Olympics, winning the 400m freestyle in 4:02.67.
Ledecky, who set the world record of 3:59.13 at the World Championships in Kazan, Russia, in August, notched another time faster than that of the year's second-ranked performer -- Sharon van Rouwendaal of the Netherlands who clocked 4:03:02 at Kazan.
"I am happy with where I am right now," Ledecky said. "I have never swum a long course meet this early in the season, so I don't really have a comparison, but I am right on or faster than what I am at these meets throughout the year."
