Can fielders do this? 2 situations

[Tap]

On #1, I think I also used my arms to wave off another OF. As for me stating that I short-hopped it, I may have misstated it a bit. It was sharply hit and I fielded it on one bounce, but there was no way I had a shot at it even if I dove (which I would have done back then). The fact that the umpire did not tell me why it was a problem with him led me to believe that there was nothing in the rule book prohibiting it and that he may have been implying it was somehow unsportsmanlike.
