Listeners of the podcast should be well familiar with this format. Paul Sporer and I try to come up with a few salient points about each player to help you make your decisions. So This week I thought I’d help as many of you as I possibly could with one article. So let’s take three (okay six) hitters and three pitchers from the twitter mailbag and have us some fun.
In looking through the largest discrepancies between in game production and my various xStats, namely xOBA, I noticed that four of the largest differences come from the Yankees. Disturbingly, these are in the negative direction, meaning xStats are making a claim that these four Yankees are playing over their head and are due for a regression. Who are these Yankees? Didi Gregorius, Carlos Beltran, Jacoby Ellsbury, and Brett Gardner.
Three left handed hitters and a switch hitter playing in Yankee stadium, a ballpark geared for left handed production. On first blush, you might scoff and claim the stats aren’t accounting for the ballpark, these guys are probably benefiting from the short porch. Yes, they likely are benefiting to some degree from the short right field fence, but last season didn’t seem to have this problem with the xStats from these four batters.
The All-Star break is a time to furiously send trade offers before those bottom half teams check out, or at least try to entice them back to their computers for one last look at their teams so that they might help you improve yours. But we’re all in different types of leagues, so instead of a few mixed-league buy low players, I thought I would try to dream up some buy-low players for every situation. I won’t cover all of you, that’s impossible with the proliferation of fantasy baseball styles these days, but maybe I’ll cover more of you.
Back in March, I made some bold predictions, as all RotoGraphs staff do. Some bold predictions I make simply for the sake of being bold. Or for the sake of making a prediction. One of the two. But I don’t have a vested interest in my predictions, mostly because (1) they typically suck and (2) I don’t own many, if any, shares of the subjects of my predictions (because, well, the predictions suck). It’s kind of like not putting your money where your mouth is.
In this case, I absolutely have a vested interest in Jose Ramirez. Chris Mitchell and I both hold a special place in our hearts for him. I’ve come to realize, in my years of watching and loving baseball, that I most appreciate the hitters who are (debatably) underappreciated contact hitters. Victor Martinez. Pre-breakout Daniel Murphy. Nick Markakis. Martin Prado. Reggie Willits???
Speaking of Prado, Ramirez looks like peak Prado right now, and in more ways than one:
It’s not like we need to talk about Jonathan Villar. We have all seen what he’s doing. But when a guy seemingly comes out of nowhere to become a top-10 fantasy player, it’s usually a big deal. What gives? Who cares. We’re here now. Let’s talk about Jonathan Villar.
Villar is on pace to hit 13 home runs, steal 60 bases, and bat .292. That’s 2014 Jose Altuve, but more power and less batting average. We’ll check the validity of all those paces in a second. The middle one is really not open for much contention, though. It took 16 games for Villar to steal his first two bases this year, but he hasn’t gone more than five games since without successfully swiping a bag. With 21 steals in the 45 games since April 23, he’s basically taking an extra base every other day. Billy Hamilton who?
Neither the speed nor power should have caught any of us by surprise. All of it is well-documented, dating back to 2014. Blake Murphy gave Villar his due back then, noting a 10-homer, 30-steal, .250 hitter is “immensely valuable” given the paucity of talent at shortstop. That has obviously changed this year, what with Corey Seager and Francisco Lindor and Carlos Correa and all that jazz. (Despite their presences, Villar still holds his own.)
Just straight hitting the ball hard has its value, but there is an ideal angle. Hit the ball a million miles per hour into the ground, and you’re Giancarlo Stanton, grounding out to second base on the hardest hit ball so far in the Statcast era. You gotta hit it square.
People smarter than I am have determined that the ideal launch angle is between ten and thirty degrees. That combines the line drive angle (10-25 degrees) and home run angle (25-30), but in fantasy baseball, we’ll take a line drive or a home run, either’s fine.
So if we want to know who’s hitting the ball harder this year, it’s probably best to ask who’s hitting the ball harder in the right angles for success? That will tell us a little about some hot starts that are more believable because of what’s going on under the hood.
I’ll pick up on the prospect theme that Justin and Tom touched on in this week’s podcast: helium watch. In other words, here are a four somewhat under the radar prospects that have caught my eye this year that could have increasing value over the second half of the season and turn into real assets in the near future in Ottoneu (and other deep leagues).
I used 10% Yahoo ownership as the cutoff for these selections. With these players available in nearly all leagues, boosting your middle-infield production isn’t as dire a situation as it may seem.
Derek Dietrich (9% owned) – With Dee Gordon suspended through July, Dietrich’s got a stranglehold on the second-base job in Miami for the next two months. For the most part, he’s been batting leadoff, although he’s hit in the No. 3 spot for the last two days, to accommodate a red-hot Ichiro Suzuki in the leadoff spot. Regardless, he’s hitting in the top third of the lineup, with a .293/.400/.485 slash.
The 26-year-old’s home-run power hasn’t shown up yet this year — with just two in 120 PA — but he’s got seven doubles and three triples. Don’t be fooled by that paltry ‘2’ in the HR column, because Dietrich has plenty of pop to get the ball over the fence. While his .355 BABIP suggests likely regression in his AVG, those of you in OBP leagues can reap the benefits of his 10.0% walk rate — and the fact that he’s strangely adept at being hit by pitches.
It was suggested that we should celebrate the day that stats stabilize. Today is Grounder Day! Eat a sloppy joe while sitting on a blanket. Drink one of these, or some of this, but I don’t know about having any of this. Grounder Day!
Well, we actually aren’t all the way there. Only about twenty players have officially reached the stabilization point for ground ball rate. But that’s fine. It actually serves as a reminder that stabilization is not something that magically happens at one point. Stabilization happens over a spectrum, and today we know a little more than we did yesterday, and tomorrow we’ll know a little more.
But! Relative to *other* stats on our leaderboards, we know a good deal about a player’s ground ball rate by now. And the beauty of that news is that just knowing a player’s change in ground ball rate can tell us a good deal about what sort of power we should expect from them going forward.
We are lost in the sea (puddle?) that is the small sample size portion of the season. We’re trying to find a mooring, some stat that we can really use to identify believable results. This is where I link you to the pieces about stabilization of stats, wipe my hands demonstratively and end the piece with a leaderboard.
Wait, I am going to do something like that, but with a few words of caution and analysis as well. For one, it seems to get lost that stabilization is merely the point at which the stat itself is more meaningful going forward than the league average. In other words, league average regression is still meaningful after this point, and the stat itself is still meaningful before that point. It’s all a continuum.
Instead, use the list as a way to judge the relative importance of stats. Easy enough. We’re past the point of stabilization for swing rates — not for reach rates or contact rates — and we’re not at the point where ground ball and fly ball rates stabilize. And yet, we can use swing rates, and ground ball and fly ball numbers, to judge players, because those stats are more meaningful than the others.
There’s also a second level here that shouldn’t be swept aside. Swinging less and hitting more fly balls is not — by itself — the greatest marker for improved performance. Some players should swing more and hit more grounders, of course. But here we’re going to look for guys that could benefit from better plate discipline and who could gain more power from more fly balls.
