Guy Boston discussed betting under for Yainer Diaz, referencing unfavorable matchups against Chris Paddack's secondary pitches (changeup and slider). While acknowledging Diaz hits fastballs effectively, Boston noted Diaz struggles greatly against changeups (wOBA dropping from .329 to .219) and sliders. Given the expectation Paddack will utilize these secondary pitches frequently against Diaz, Boston considers Diaz under props a valuable wager. He specifically used detailed pitch mix data from Outlier to reinforce Diaz's vulnerability against pitches he's likely to see today.
