Michael Phelps was a man on a mission Sunday night at the 2015 US National Championships, claiming yet another national title in the 200m IM and putting a scare on the world record.

With the fastest time recorded by any swimmer since he won the 200m IM at the London 2012 Olympic Games, Phelps went straight to the top of the 2015 world rankings bumping Ryan Lochte‘s winning 1:55.81 from the world championships to second.

At the touch he was a 1:54.75, 1.06 seconds faster than anyone in the world this year. The time ranks as the eighth fastest 200m IM ever recorded, knocking his 1:54.80 from the 2008 Olympic Trials in Omaha to ninth. Phelps currently owns five of the top 10 fastest times ever in the race.

Phelps was under Lochte’s world record pace for the first 150-meters, however fell short on the freestyle leg. Taking out the fly hard, Phelps was well ahead of everybody after the first 50 turning in 24.65.

With a swift backstroke leg Phelps kept pushing forward, turning in 53.14 as he continued to stay under world record pace. After his breaststroke leg Phelps was a lock for gold, turning for home and touching for gold.

When comparing Phelps’ splits to Lochte’s from worlds, the real advantage for Phelps came in the fly and backstroke. Lochte usually has the edge on the breaststroke, however this year both Lochte and Phelps were identical on the breaststroke legs.

The area where Phelps race lacked the most from recent years is the freestyle leg. Phelps slowed down a lot on the way home, splitting a 28.27.

When asked about a potential 2016 200m IM rematch with Lochte, Phelps said, “I’m looking forward to getting back in and competing with him.” Citing the breaststroke as his weakness, Phelps said he’ll be looking to improve that as the Rio Olympics approach.

Phelps is currently the only male swimmer ranked first globally in three separate events in the 2014-2015 season.
