Pedroia
6743 career PAs
When he swings at and puts the ball in play, his OPS is ..
.860 in just 367 PAs (under 5% of first pitches)
He has 3474 PAs with on 0-1 count, so we can surmise he swung and missed or took the first pitch for a strike 53% of the time.
He took the first pitch for a ball 2902 times 43% of the time.
Once he goes to 1-0, he ends up at a .916 OPS.
Once he goes to 0-2, he ends up at a .716 OPS.
You can't just look at his numbers with an 0-0 count. By taking the first pitch so often, he sets in motion another dynamic that has to be figured into the data, not just the .860 OPS when he rarely decides to swing AND makes contact.
Look at it this way, when the first pitch is throw for a strike (called or swung at) or swung at and put in play, Pedey puts the ball in play for just 11% of those incidents 367/3841 or less than 10% of the time.
(367+3474=3841)
I'm no math expert, so correct me, if I am wrong.
