S.Burke u5.5 Ks-154

0.5u

Gets the T-Mobile park K boost today, but my expected K model has him as a 18% K guy so far this year (and trending down). Not having the auto K that is Cal Raleigh in the M’s lineup makes them a tougher lineup to K. Plus, I have him at a 50/50 chance to get pulled before Luke Railey’s 3rd time up which is another sneaky path to his under. Proj this closer to -200. Some books have this at 4.5 and I have fair price for that under closer to +105

E.Hancock u4.5 Hits Allowed-108

0.54u

White Sox will likely have a L heavy lineup which actually helps Hancock who has reverse splits in his career where his K/BB rate are both higher and BABIP lower against LHB which all 3 factors help the under. Plus it’s a home/day game which are splits that also help his under. Projecting this closer to -170
