I'm a longtime veteran of Road to the Show, so it's been second nature to me.
I use Analog baserunning controls. To steal, this is what I do:
- I don't try to take an extra step. Too often it's not worth it.
- Hold R1 to lean toward the next base.
- Hold the left stick to the left so that you immediately return to the base on a pickoff attempt. With no extra leadoff, it's virtually impossible to get picked off if you do this. I do this out of habit even if I'm not stealing.
- Upon movement toward the plate, push the left stick to the right to run.
- Slide by holding L1 and using the right stick to choose the slide type (up for head-first, down for feet-first, left and right to chose the side of the bag to slide to). Having to hold L1 to slide is new in MLB 20.
While you're running, you can hold L2 to show the broadcast camera or hold R3 to keep both your player and the ball in the frame.
