One of the few bright spots for the 2019 Baltimore Orioles was starting pitcher John Means. The soon-to-be 27-year old lefty finished second in AL RoY voting and posted a 3.60 ERA over 155 innings. Things look great, huh?
Well, maybe. Means also had a FIP of 4.41 and an xFIP of 5.48. The discrepancy between his ERA and FIP (E-F) ranks 8th among MLB starters who pitched 150 innings or more. (All rankings going forward are for MLB SPs with 150 IP or more in 2019.) His K/9 just barely eked over 7 and his BABIP allowed was a likely unsustainable .
