Also happening while I was sleeping, United States smashed Spain in the final of women's water polo, but Kyle Snyder was defeated in the men's freestyle < 97kg final.
4-for-5, with two still being contested, and one to go. Barring a miracle, USA is going to come up short on both of those other two (baseball/women's high jump), as well.
On the bright side, China surprisingly only went 1-for-3, in the events they were favored to win (although they did pick up an unexpected canoe gold)
