Sounds like a rhetorical question, yet I'll answer it. 😀 Split the season at the mark where Margot hit bottom in OPS, namely May 17.
92 PA, .169 BA, .468 OPS, .203 BABIP
Since that date:
53 PA, .340 BA, .883 OPS, .381 BABIP
A straightforward way to look at it is that the BA on Balls In Play leads the way for the rest of the stats, and a nice stretch where the hits are falling in for him have helped bring him close (but not quite there yet) to career norms having a BA in the range of .250 and a BABIP just short of .300. A little more of this good stretch and then normal rates of hits falling in could keep him as a backup the rest of the way.
That second line of numbers is no more believable than the first one, as a reflection of him as a player, and the truth lies somewhere in between, which the accumulated season stats are now reflecting. There are people who are (rightly) skeptical about this current good stretch, and yet were willing to take the bad stretch at face value.
"Which player do you want, Player A or Player B?" "I want Player B, obviously." "Ha! They're the same player."
Mind, such numbers as backup would be what I presumed would be tied to CF skills, an expectation that most of us have found disappointing. These are not numbers for a backup corner outfielder, regardless of the quality of defense there.
