HT: USA 0-0 Japan

The cries of "USA, USA" follow you pretty much wherever you go at the Olympics but here it is being used by the fans as a bit of an impatient slow chant rather than one of excitement.
It's been a pretty slow match so far with not much to write home about.
Lindsey Horan saw an early effort smothered by Ayaka Yamashita and Sophia Smith has had a couple of chances while Mina Tanaka saw her low drive saved and Miyabi Moriya's volley blazed over the bar at the other end.
All square at the break.
