"He was five plate appearances shy of posting the second-worst qualified OBP since 1900, and the worst since Hal Lanier in 1968."
"And… it’s true. Technically. If you drop the cut-off to 250 plate appearances– essentially half the number that Arencibia had this year– and he tumbles down the worst-ever-OBP list… all the way into a tie for 37th place.
That’s right, a mere twenty-three thousand eighty-eight seasons of 250 plate appearances or more have produced a better on-base than Arencibia did in 2013."
