Can anyone explain usa women’s soccer -3/4 -132 vs japan?

[Aristo]

I understand it must not be as simple as usa 1 japan 0, so its a win..why -3/4? Does it have to do with extra time, or anything else? Thanks in advance guys!

If USA wins 1-0, you win half your bet. You're betting half at -1 and half at -.5.
