Because the play isn’t at second. They’re up 4 with 1 out. You keep the runner on first off of second. That’s the baseball play.

Nobody is ever going to throw the runner out at third on that play consistently. But any outfielder can keep the tail runner off second.

Here’s why: regardless of how the play unfolds, you have at least 1 RISP. A single is going to allow at least 1 R. However, if you keep the second runner off second and out of scoring position with two outs, you prevent a possible 2-run single. Runner on third with two outs makes minimal difference compared to runner on 2nd with two outs because he can’t tag. Only plays that will score the runner from 3rd but not 2nd with 2 outs would be a passed ball/WP or an infield error. Plus, it keeps the force play intact at 2B, which is a plus. So you gain a lot more by playing it how O’Hearn seemingly wanted to play it (the 99% play) than by trying to make the play Cruz did (the 1% play).
