Brandon Lowe & Christin Stewart: Deep League Wire
This week’s edition represents a reiteration of two previous recommendations. It baffles me both are owned in less than 10% of CBS leagues.
This week’s edition represents a reiteration of two previous recommendations. It baffles me both are owned in less than 10% of CBS leagues.
Yesterday, I highlighted five lesser owned hitters who have running wild over the last two weeks. Today, I’ll discuss four hitters who have posted absurd HR/FB rates over the last 14 days. These players are all widely available and could knock another couple out, which may be the difference between a point or two in the homer category, and perhaps RBI.
At a stolen base attempt every 54.8 plate appearances, hitters are trying for a swipe at the lowest frequency this century. That means it’s more difficult than ever to find steals on free agency to gain points in the category. Luckily, there are a handful of hitters who have attempted a bunch of steals over the last two weeks and aren’t owned in the majority of CBS leagues. Let’s discuss them.
It’s been a banner year for rookie players in 2018. This season we’ve seen the graduation of the minor leagues best all-around prospect (after the obligatory service time manipulation), a two-way phenom contribute on the mound and in the batter’s box, a 19-year-old that began the year in A-ball, and the Yankees continue to profit from their embarrassment of riches.
I use xwOBA as a leading indicator of good or bad things to come mid-season, for better or for worse. It’d be good to know if such reliance is truly warranted. I further talked myself into the idea when I wrote about several underperforming hitters in early June. Many of the names therein went on some serious heaters afterward, too. It wasn’t as prescient as it was playing the odds: the hitters underperforming xwOBA most extremely through two months always, always (in the Statcast EraTM) bounce back to some degree.
It’s “predictive,” but not universally so, and only by virtue of common sense, in the same way a pitcher who allows a sub-.200 batting average on balls in play (BABIP) through two months could not reasonably sustain this high level of contact management. (There’s a discussion to be had here about the gambler’s fallacy, but I don’t think it necessarily applies to baseball. For another day.)
In terms of prior work, it’s all Baseball Prospectus‘ Jonathan Judge (only a slight exaggeration): he compared xwOBA to BP’s DRA metric as well as FIP (fielding independent pitching), a much simpler ERA estimator, and showed xwOBA is hardly superior to the field, at least for pitching. However, the article only covered year-to-year, not in-season, correlations.
After our dear and departed (but not dead) Eno Sarris asked Judge if he had looked at in-season correlations specifically, and after our dear and departed (and also not dead) Mike Petriello reinforced the notion that xwOBA could serve as an in-season predictor of regression under certain circumstances, I figured it’s high time I just tackle the question.
So: How predictive is xwOBA of wOBA in-season? For hitters and for pitchers?
The theme of this week’s deep league wire is POWER. Lots and lots of power. And unfortunately, perhaps nothing else. Most of you could use a couple of extra homers, right?
I think there are not one, but many, questions because there are not one, but many, ways Adalberto Mondesi and Byron Buxton are similar.
Here’s one answer to one possible question:
who has the best fantasy season in 2019?
— Alex "Oxlade" Chamberlain (@DolphHauldhagen) August 29, 2018
I can’t say I’m surprised, but I’m kind of surprised. I asked this question very deliberately, its design not remotely accidental, the response options dripping with subtext. Mondesi, with his elite speed, decent power for a speedster, and very questionable contact skills, in 2018 is almost a dead ringer for Buxton in 2017. Mondesi doesn’t quite have Buxton’s baggage — he doesn’t carry the weight of expectations of a No. 1 prospect — but he has his own, continuing a familial legacy. But they do have a lot in common, as aforementioned, which can be summarily boiled down to this great quip from our Eric Longenhagen: “wholly untamed physical abilities.”
Looking over the last 30 days, I toured the diamond for a standout at every position who could be available and continue to produce over the final month of the season.
C: Omar Narvaez, CWS | 148 wRC+, 2 HR, 5 RBI, 12 R, 0 SB in 73 PA
The 26-year old backstop was supposed to be a backup, but then Welington Castillo was suspended 80 games for PEDs. Narvaez has made the most of his opportunity with a 127 wRC+ for the season. He’s more than just the last month of time, too, as he’s hitting .349/.433/.544 in 172 PA since June 1st after a paltry .169/.273/.234 line through May. Castillo’s suspension is done, but now he’s on the DL with shoulder inflammation. Narvaez is a solid C2 even when Castillo returns.
In just a couple of days, rosters will expand, new faces will be recalled, and you’ll have a slew of choices for your deep league teams. But until that time, you’re still stuck with the same group of mehs. Here are two recommendations.
