Baseball fans: what would you want explained first?

I built this to translate live cricket into baseball terms, so the thing I most need to know is where the translation should start.

The ones I picked so far: wickets are outs (you get 10, not 27), "126/7" is a countdown rather than a fraction, an over is six pitches from one end, and a T20 innings is a fixed 120-ball budget rather than a fixed number of innings.

If you have tried watching cricket and bounced off it, what was the exact moment you lost the story? And if you already know cricket, where do you think a baseball comparison breaks down?
