SANTA CLARA, California, May 3. CALIFORNIA's Nathan Adrian blitzed the men's 100-yard free today at the U.S. Masters Nationals and tied his American record in the process.

Swimming in the men's 25-29 age division, Adrian surged to a 41.08 in the 100-yard free today in Santa Clara. That swim matched his American record of 41.08 set in College Station in 2009. It also happened to demolish the USMS national age group record of 42.13 set by Darian Townsend a year ago.

USA Swimming let Swimming World know today that the USMS Nationals meet is on its observed and approved list, and as long as everything else is clean, this swim could be ratified as an American record.

Here are the splits in the race:
1 Adrian, Nathan 25 TOC 42.00 41.08N
19.74 41.08 (21.34)

It was later revealed by USMS that Adrian actually had posted a 41.13 officially.

Adrian beat Townsend head-to-head as well with Townsend taking second today in 43.13. The day also featured Adrian's teammate Anthony Ervin crushing the men's 30-34 100-yard free record with a 43.18. Mike Picotte owned the previous mark with a 44.53 from 2004.

Additionally, the ever-popular Josh Davis turned up the heat in the men's 40-44 100-yard freestyle with a 45.15. That time beat Michael Ross' age group mark of 45.35 set back in 2008.
