Yesterday's Ninth Inning:
Fly ball
Walk
Line drive
Okay, yeah, that is not good, but still no runs had scored. Bases were loaded, nobody out and here is what happened next:
Ground ball
Ground ball
Ground ball
Ground ball
(Pick off)
Ground ball
Line drive
Ground ball
Based on the linear weights of these individual events, the expected total outcomes of this string would be 1.6 runs and 7.3 outs. Instead we got five runs and three outs.
Bad luck.
