Lot’s of fun and fast swimming here on the first full day of the 2015 USA Swimming Pro Swim Series in Mesa, Arizona. There’s no doubt that Michael Phelps’ return has sparked a lot of interest here in the desert, but there was also a lot of strong swims across the board – a good sign for the upcoming summer season. Our chief swim photographer Mike Lewis is on hand helping us bring in some of the images the weekend. Here’s the big day 2 photo vault.

Love your incredible shots Mike – always so clear & it shows how beautiful swimming is .
Thanks @ERVINFORTHEWIN
Mike Lewis, Your potos are dazzlingly good! How do you capture moments like this when I can’t even get my autofocus to work correctly?!
Great question at the Phelps Press Conference too! 🙂
Thanks DANJOHNROB
