According to fip, if you give up four doubles off the wall and strikeout three to get out of the inning, you just had an outstanding inning whereas if you give up a solo homerun and get of the inning on three weakly hit infield dribblers you had a bad inning, even though you gave up 1/3 of the runs and got hammered 1/4 the amount of times. That’s why it doesn’t make sense. FIP isn’t a particularly sound measure since it concludes that since fielding may have an impact on some plays, that all fielded balls are irrelevant when it comes to the measure of the quality of pitching. Which is clearly ludicrous. I mean it’s still an interesting stat, but way too much credence given to it when its entire premise, that fielded balls are irrelevent, is completely unsound.
