Given Bobby's upsetting situation, it looks like the men's team will be Duehring for the omnium and Baranowski for the keirin.
If I had to guess, the women's TP team will be Valente, Hammer, Winder, and Catlin, with Geist as the fifth (and Hammer also riding the Omnium). Not sure if they'll be able to field sprinters - I always get confused about how qualification works.
