Can I take a crack at it? I think it also comes down to Lee did not advance because he was not expecting France to try to advance.
The rule of thumb has always been, “If it’s hard hit to the left side of the infield, hold your base until it goes through.” This is how kids have been coached if they are on second or third, no force play, and less than two outs, for hundreds of years. 🙂
So whether Lee missed a sign or France hallucinated a sign that wasn’t there, Lee’s instinct kicked in once the ball was hit, and Lee expected France to stay at third. So, Lee stayed at second.
At this point we can talk about decisions being taken out of players hands since the StatCast era came in, no more two-strike approaches at the plate, no more rogue base stealing or baserunning decisions being made out there (thankfully that is now changing the past couple seasons), but that’s a whole nuther discussion.
So that’s my twist on it.
There’s no way France or any other average runner breaks for home on that ground ball on their own accord, 10-15 years ago.
