I like the Statcast stats a lot. They are designed to take into account quality of contact and placement of batted balls, with their attendant likelihood of falling in safely, to help us understand how well a player is doing in the thing they are supposed to be: driving the ball hard if they're hitting, and inducing soft contact if they're pitching. There's really nothing else hitters and pitchers can actually try to do. Outside of bunting for hits, or doing swinging bunts, batters really can't "try" to get base hits other than hitting the ball hard and hoping you did it right so it will fall in.
Granted, these are forward-looking metrics. Soto's stats said he was doing great: 1-0, 3 saves in five appearances, 1.59 ERA. But his Statcast card indicated that this was a mirage, and in this particular case, we happened to see the result Statcast forecasted versus his traditional stats.
Statcast's intention is not to tell us how a batter did in terms of slash lines or outcomes, but rather what we can likely expect the batter to do in future at bats, under the reasonable assumption that if they've been hitting the ball hard and bad-lucking into outs, they can probably expect more hits to fall in if they keep hitting the ball hard like that. Yes, that's an assumption, and sure, "ass you me" can always apply. But it's a better assumption that the batter continue to hit the ball hard as his track record has indicated than it is to assume that a batter's quality of contact is a completely random circumstance, or worse, that a batter is going to suddenly change how hard he's hitting the ball because he's due.
Ironically, FIP is very much also a process-oriented stat like the Statcast stats are, in its attempts to weed out the luck of outcomes from balls in play and boil it down to what a pitcher''s ERA "should be" based on the things he can better control: strikeouts, walks, HBPs, homers. In this way, FIP is quite related to Statcast stats. wOBA on the other hand is very outcome-oriented and has nothing to do with quality of contact.
