It's so weird. (I'm obviously looking at the same page of stats as you are.)
Man on third only? OPS is a reasonable .793 in 72 PA - better than their overall average, almost exactly MLB-average (.785) this year for this situation.
Man on second and third? OPS .950 in 62 PA. All-Star good. Fourth in the majors.
Man on first and third? OPS 1.112 in 91 PA - Hall of Fame good. We lead the majors.
Man on first, second and third? OPS .451 in 85 PA. What the what?
I really think this is "one of those things" due to small samples, that hasn't evened out yet in the course of time. What in the world would distinguish these scenarios from one another in terms of clutchiness?
Merely grazing the uniform is sufficient for it to be a tag, so the baserunner may not be aware if a legal tag is made. He has other things on his mind in that instant anyway.
Okay, but this sounds like if there is simply an opt-out, then if it's not exercised on or by the date specified, the player is committed for the rest of the season. Which makes sense, I just want to know.
