They are called “sliding gloves.” I didn’t see anything in there at all regarding sliding gloves. I’d imagine that, like pretty much everything else that’s not codified in the rules, it’s umpire’s discretion.
“Things that make a mockery of the game”, like sending a little person up as a pinch batter, can be called by the umpire. If a runner dons a 90 foot long sliding glove, even if there’s no specific rule against it, would be called under the mockery rule, I think.
I can’t find a rule in there that says players can’t wear their fielding mitt while running the bases, or what constitutes touching a base. It’s a horribly organized document so all that may be in there somewhere, but it’s very poor at defining some of the terms it uses.
AS DCnDC and** kayaker** pointed out, it’s up to the umpire. If a runner objects to the umpire’s ruling on his glove he’ll have to find the rule that permits it.
If this is becoming a huge concern I’m sure MLB will address it this off-season. No one is running the bases with a 90 foot glove or a foam finger!
