watching the runner to see if she leaves early

[Steve M]

I confess. With a runner on 3rd AND 1st and/or 2nd, I give very little attention to the runner on 3rd as far as leaving early on the pitch goes. The others are far more likely to leave early. There's just about no reason for the runner on third to jump early. And, it's a whole heck of a lot easier when working a 3-man crew (as is just about everything else on the field).
