Michael Phelps qualified for one top final and missed another in his first events at a Pro Swim Series meet in Minneapolis on Thursday morning.
Phelps, competing for the first time since he won three events at the U.S. Championships in August, finished tied for fourth overall in the 100m butterfly prelims in 53.70 seconds at the University of Minnesota.
He made the top eight-man final (7:37 p.m. ET, USASwimming.org) along with Ryan Lochte, the second-fastest in the morning at 53.27.
Phelps was 10th overall in prelims in his other event Thursday, the 200m freestyle, which he hasn’t been focusing on in his comeback from a 20-month competitive retirement following the London Olympics. Lochte was third in qualifying in the 200m free, making the top eight-man final (7:11 p.m.).
Phelps was .18 faster in the 100m butterfly prelims Thursday than at this same meet in November 2011. He was .99 slower in the 200m free prelims than in 2011.
Phelps and Lochte could face off in the 100m backstroke and 100m freestyle later in the Olympic season-opening meet that runs through Saturday.
In women’s events, Katie Ledecky and Missy Franklin were the first and third seeds, respectively, into the top 200m freestyle final (7:03 p.m.). Olympic 200m free champion Allison Schmitt qualified fourth.
Ledecky later beat both 2012 U.S. Olympians in the 400m individual medley (Elizabeth Beisel, Caitlin Leverenz) in her preliminary heat in that race but was touched out by Becca Mann.
Ledecky has said she may swim the grueling 400m IM at the Olympic trials, in addition to her trademark freestyle events. She’s the No. 2 seed going into the final (7:47 p.m.) behind Mann. Beisel also made the top final, as did Maya DiRado, the World silver medalist in the event.
Olympic champion Dana Vollmer was the second-fastest qualifier into the top 100m butterfly final, .19 behind Kelsi Worrell. Worrell is the fastest American in the event this year, while Vollmer is coming back after having a baby boy March 6.
*Correction: An earlier version of this post incorrectly stated Caitlin Leverenz made the top eight-woman 400m individual final. She was ninth in qualifying, according to SwimmingWorld.
