Results after the jump. It should go without saying that if you don't want anything spoiled for tonight (particularly with regards to swimming), you should skip this post until you've watched the primetime telecast. There will be a live thread for tonight's tape-delayed broadcast on NBC.
For those who want to know how our Cal athletes performed, read on.
Women's 4 x 100 meter freestyle
Natalie Coughlin and Jessica Hardy earned the first medals for Cal of these Olympic games when the United States finished third place behind Australia and the Netherlands for 1st and 2nd place respectively.
Coughlin competed in her only race of these Olympics games, posting the fastest split in the first round heat for the USA at 53.93 seconds (watch it here). Coughlin didn't compete in the final, but Hardy did, and as part of the second leg helped keep the USA ahead of Australia by a few hundredths of a second with a 53.53 second split. Australia and the Netherlands did eventually overtake them, but Coughlin does earn her 12th medal to tie her with Jenny Thompson.
Women's 100 meter butterfly
Dana Vollmer finished with an Olympic record of 56.25 seconds in her first heat, which was the fastest time. You can watch her Olympic record heat here. She stayed on top in the semifinals with a time of 56.36 seconds, which should make her the big favorite going into tomorrow.
Women's 400 meter IM
Caitlin Leverenz just managed to get into the final with an eighth place finish in the heats, then managed a tie for sixth with Stephanie Rice in the final with a time of 4:35.49. Leverenz's strongest event (the 200 IM) is still to come.
