From the 1B angle I thought he clearly didn't swing.
And the play at the plate I wasn't surprised they let stand. The foot clearly beat the tag, but it looked to me like the toe hit the dirt, bounced up, and didn't get down to the plate again til after the tag was applied. That's the danger with the foot first slide on a close play, it's really hard to get the front of your foot down.
No matter, this team doesn't care.
