So that’s a thing now. Rex Maurer has shown the world that even college-aged swimmers can drop nearly 7 seconds in their best event as if he hit a growth spurt. Maybe he did.

The Texas sophomore is only a summer and fall semester into his time in Austin following his transfer from Stanford where he had a solid freshman year. But this Longhorn mid-distance crew is different. It is stacked with hitters, as demonstrated with Carson Foster breaking the American Record in the 500 about an hour before Rex decided he’d like that title on his CV. Maybe this reset the 500 freestyle has seen in recent years (see also Leon Marchand’s otherworldly underwater freak show 4:02 from 2023) will translate to the long course 400 and finally deliver the much-awaited sub 3:40 that has eluded the world’s greatest swimmers since Thorpee.

Rex Maurer, the son of an Olympic swimmer and head USC coach Lea Maurer, swam lifetime bests in the 400IM, 1650, and 200 freestyle, all at a mid-season invite, and he is now expected to haul in points for Texas at the 2025 NCAAs as one of THE swimmers to watch in March.
