There are no "off-meets" for these two. From Swimming World:
"...In a head-to-head battle between a pair of Olympians, the veteran Jason Lezak challenged the American record in the men's 50 free with a triumph over Nathan Adrian. Lezak, swimming for Rose Bowl Aquatics, won in 21.90. The American record is held by Garrett Weber-Gale with a 21.47 from the 2008 U.S. Olympic Trials.
Texas Senior Circuit: "...Longhorn's Aaron Peirsol crushed the field in the men's 200 back with a swift time of 1:56.38. [about 2-seconds off his personal best - Tony] Mustang Matt Thompson placed a distant second in 2:01.52 with Timothy Johnson taking third in 2:04.52.
I grabbed the photo to the right of Jason Lezak at his website. (Yes, I did alter he photo.)
Can anybody tell me what suit he is wearing? It is kind of snazzy!
