Chase Kalisz of North Baltimore Aquatic Club had a little company over the first 100 but he was all alone from the first couple of cycles on the backstroke leg onward. An incredibly strong back-halfer, Kalisz continued to build his lead and was about 10 meters ahead of the field at the breast-to-free turn. Kalisz finished well and touched in 4:12.80 for the win and the second-fastset 400 IM in the world so far this season. Max Williamson of Stanford was second in 4:20.86, just a tick ahead of Gator Swim Club’s Dan Wallace(4:21.03).
