When I say we're now at a time where stats are real I mean we're at a time where it takes more than a hot week to change your fortunes. I've mentioned this before but let's take an example. Joey Meneses is hitting .294 / .333 / .381 right now. If he were to get SUPER HOT over the next week, hit .500 with 5 doubles and 2 homers, get walked 3 times (a lot for him) his stats would shoot up to... .319 / .360 / .440 . It's a nice bump but he's not suddenly great or anything. If he were to go ICE COLD, hit .100 with a double and a walk his numbers plummet to... .270 / .309 / .351 Disappointing but not a problem player.
No, at this point you need to have an extended run of good or bad hitting to make a sea change. Guys can (and will!) get better and worse but we have a good sense of around where they'll end up. Most will end within 20 pts of their OPS+. Yeah it's a big range but it also tells you things like it's really unlikely Joey Meneses ends up a star again. or that Lane Thomas will be anything worse than average.
To be clear the forecasting we're doing here is 2023 only, not related to how these guys might pan out over careers or anything.
So what seems real today?
Keibert Ruiz / Luis Garcia / CJ Abrams - not going to be stars this year with a non-zero chance of collapsing. I'd guess all three end up around where they are now, maybe a tick higher. Both Ruiz and Garcia have stats to back up a little better numbers and Abrams has the pedigree. But for a team looking for stars it's not coming from these guys this year.
Thomas - certainly a starter and might be special? He came from an overstocked Cardinal OF not because he wasn't liked, but because they liked others better. The talent was there to be something and he's never failed when getting the time to shine.
Meneses - is not special? There was a fair amount of thinking the Nats found something last year but with teams having a book on Meneses and the fairy dust gone away they've cut his power by feeding him more junk. Maybe if he were 19 you'd say he could adjust but at 31, nah. Be glad he has talent enough to keep that average up.
Candelario - good gamble. Plays solid D and hits fine. Mostly proves last year was the injury fluke the Nats were hoping it was. I'd try to lock him up for a few years with no IF on the immediate horizon. If he gets pushed by like House then 1B seems open. Speaking of which.
Smith - money back. He started poorly but has rebounded to a point. The big issue is the power of 2019 and really 2020 - remains gone. If the BABIP goes unlucky he'll be an anchor. He's a back up player for most teams in 2023. For the Nats he holds ground if they want him to.
Call - bad gamble. They liked throwing him out there but he never got going at the plate. With the upside being average and the downside being terrible, the Nats should move on.
with less conviction :
Robles - transformation at the plate makes him good again. Play him everyday if/when he gets healthy.
Garrett - got his shot (Really did this time) and doesn't look to be anything, but may benefit with another set of PAs if the Nats give up on Call like I suggest.
Corbin - A rotation guy. Outside of 2021 he has been this honestly but some bad luck made him seem worse and when you are pushing 4/5 worse is out of baseball. This year things are more in line and he doesn't miss bats anymore but he's adapted enough with increased patience and focus that he can eat innings.
Gray - Also a rotation guy but cloudy on where .The ERA says 1. The FIP says 4. He's basically the same pitcher as last year but the HRs are WAAAAAAAAY down and the Ks are down a little. It's a good trade. But his LOB% and HR/FB% are at the level you expect regression... The good news take away for 2023 is he's not threatening to be pulled from the rotation. He's here to stay. The rest of the year is clarifying where.
Gore - Mid rotation guy right now. Slight improvements across the board from last year. Really working those Ks. Don't see him falling past 4 but probably not jumping to a 1 in 2023.
Williams - Like Gray but the range is more 2-5 than 1-4. He's not doing anything well with more IP under his belt. striking out fewer while giving up a few more hits and homers. The end result is he's losing his gamble on himself. For the Nats small chance he bottoms out of the rotation, but more likely not. Really the Nats got him to trade him so on that end they remain a little lucky. He's not pitching well but his ERA is hiding some bad stats now. Yes, baseball guys would know that but there is also selling it to your fans and owners. If he improves and pitches to the ERA (3.90) you can sell that easier than if he improves but he's coming down from 5.18 and sitting at 4.55.
I'm not going to bother the less conviction of the bullpen and 5th starter. Too many to throw out what amounts to 50/50 guesses
