Women's 100m freestyle

The job of practising being comfortable with solid morning heats effort was done earlier in the day, the finals about doing it right and getting a hand to the wall first. Dana Vollmer, of Cal, did it twice. First up came the 100m free, a 26.22 turn ahead of Missy Franklin the gain she maintained on the way him to a 54.21 to 54.62 win, with Allison Schmitt third in 54.72 on the way to her own victory in the 400m free. The winning time was 0.05sec inside the meet mark Vollmer set in heats.

Men's 100m freestyle

Nathan Adrian, Cal, was out in 23.07, a fair way up, as he'd need to be, on Michael Phelps (23.82). While others ahead of the 14-times Olympic gold winner could not cop with the only sub 25sec home comer in the race, Phelps on 24.92 for a 48.74 finish, Adrian could: in 25.55 to the wall, the 23-year-old stopped the clock in 48.62, a meet record inside the 48.89 of Phelps from a year ago. Third went to South Africa's Darian Townsend in 49.14, with David Walters on 49.22.

Women's 200m breaststroke

Micah Lawrence, SwimMAC Carolina, led from start to a 2:24.85 meet mark inside the 2:25.77 she clocked in heats. Lawrence arrived at the meet with a 2:25.19 from pan Pacs last year but went to bed smiling over her first sub-2:25 swim. She had company all the way in the form of Caitlin Leverenz, a medley force in the making and on 2:25.63, just 0.01sec shy of her all-time best as a 16-year-old breaststroke specialist back in 2007. Emma Schoettmer took third in 2:28.47 just ahead of Micaelle McKeehan and 2004 Olympic champion Amanda Beard.

Women's 400m freestyle

Having warmed up in the 100m free, Schmitt was back for battle with katie Hoff, the two rarely more than half a second apart over eight laps than ended 4:06.94 to 4:07.00 in Schmitt's favourite. The splits tell the tale:

• Schmitt: 1:00.48 (31.17) 2:03.34 (31.11) 3:05.23 (30.99) 4:06.94 (30.30)
