Mr Man,
I'm not going to get into point of facts or anything--I'll leave that to others. Strictly on structure. My observations, FWTW:
If you were doing twenty inches or less then I'd say your lede is appropriate but in this case, with room to breathe and space to explain, I suggest an alternative. Rather than the overview lede, might you not start with Dave Roberts coming in as a pinch runner, y'know, a move seemingly inconsequential, trivial. The last faint hope. Then get action happening: him reading Rivera, running down the basepath, sliding in under the throw. For a story about one of the most exciting plays (I don't want to hear from the Legion of Triple Loyalists) it does read a little static.
"What happened next pashes for New England scripture." Well, yeah, but that doesn't mean you don't spell it out and write it up.
And then maybe your first sentence becomes your fifth. You start with a conclusion in your lead and then rationalize/justify/prove it. Maybe if you show us it in play first you'll make an easier adjustment into the body of your text.
I sorta wish that you had shown in the lede the momentous (Roberts's steal) and contrasted it with the everyday (I dunno, a steal in a spring training game) and shown how much one resembles the other, or something like that. Figgins on Roberts as it were. Maybe even a pitcher trying to hold.
Take my musings for all they're worth. Not much.
