You don't actually make yourself slide it does it by itself. You have to click your mouse every second and your speed goes up, you have to get there before it is out. That part is Running in Pinch Hitter 3.
I'm still learning also but I picked up the catching part tonight (found your question while I was searching how the heck you run on Pinch Hitter 3?) LOLOK - The way to catch is to move your player...
