Okay, somebody help me out with baseball rules. [View all]

I've been watching videos on this appeal play in the Phillies/Pirates game. Here are two videos I've watched:

The second video says that the umpire got the call right, because the runner missed the base.
Which might make sense if the fielder hadn't touched the bag. But it looks to me like he comes down with the ball and lands on the bag. So if the runner missed the bag, why wouldn't he be done on the force out? Is a tag really needed?
