Ags swept the women's senior events on Day 4!
http://swimswam.com/2012/05/aggie-women-sweep-day-4-at-mexican-trials/Maroon Swimmer - Mexico hasn't yet qualified any relays for the Olympics. The only one they swam at Worlds last year was the 800 FR, and they were 17th in that. Top 12 at Worlds qualified, then the next best 4 between Worlds and...June 1 I believe.
Right now, that's Finland's 4:08.47. That time could improve at the European Championships.
The best leg of the relay is actually Maria Gonzalez, who was under 1:01 in the 100 back in Columbus. If you add up the times you get 1:01 + 1:11 + 1:00 + 55.5 = 1:07.5 in a good scenario. That would put them in, if they hit it.
If they want to go after it, they'll probably time trial it at the meet sometime. But Gonzalez hasn't been very good at this meet - clearly in heavy training - so they might not hit that time.
