I missed the whole race today. I'm hoping to finish some errands and watch the replay this evening. I had a quick look at the GC and can't figure out how Sagan went from the White Jersey to Green. I'm guessing intermediate sprints.

Sagan holds both the Green and White Jerseys. Bardet will just be wearing it for the next stage.
