In all candor I want to know what IKF was thinking when he was on third.
He won a gold glove there so he has to have a good amount of knowledge of that position and what the defense would normally do in that situation.
Once he saw the infield (including the third baseman) playing in, he should have taken a lead roughly one step further from third than the third baseman. There is very little chance of getting picked off as a throwaway from the catcher to a moving target who is moving away from where the throw was coming from.
He should have had a far better lead in the force at the plate and he should have run through the plate. There's a reason nobody slides into first. It slows you down, but it also (if you do it correctly) prevents you from overrunning the base (not applicable at first or home) and allows you to attempt avoiding a tag (not applicable in this case).
He screwed up on a couple levels.
