Does Smeltzer’s data include last night? It doesn’t appear to. I think FIP and XFIP are relevant to the discussion to help isolate a bit to the pitchers performance relative to ERA. Unsure of the OP’s method, I used Fangraphs Splits, filtered to the10 most likely post season opponents, Cleveland, Houston, NYY, Oakland, Tampa, Atlanta, ChC, LaD, Milwaukee, St Louis. FIP / XFIP Berrios 4.20 / 4.92 Smelter 5.48 / 4.67 Pineda 4.03 / 4.47 Odorizzi 4.65 / 4.78 Gibson 4.76 / 4.61 Perez 4.88 / 4.59 WPA isn’t in the splits tool, but also seems relevant to the discussion. WPA 2019 / Career Berrios 1.85 / 1.95 Smelter .51 / .51 Pineda .27 / 1.17 Odorizzi 1.64 / 3.56 Gibson -.62 / -2.28 Perez -.49 / -3.08 The first three on my list are pretty easy Berrios Odorizzi Pineda I know Odo has a bad FIP/XFIP against the contenders, but really strong WPA. I just don’t trust anyone after those 3. Maybe Graterol will come up and light up the big leagues? Would you dare go into the post season with three starters? This was fun! Thanks!
