Anthony Rendon: More Aggressive and More Passive, Too

Imagine you’re magically granted the power of time travel and that you use it to visit the days leading up to Opening Day 2016. Suddenly back in a world without daily regular-season baseball, you approach an unsuspecting baseball fan and tell them that you’re a time traveler with this bit of baseball information from mid-June: over the past 30 days, the Nationals have had the best offense in the National League.

The fan, presumably, would begin by chastising you for having wasted the gift of time travel on something so frivolous. Then, after gathering him- or herself, would likely respond with something like, “That Bryce Harper sure can rake, can’t he?” With the trap successfully set, you would then drop this bomb on them: “… and Bryce Harper posted a 77 wRC+ over those 30 days!”

Good job, time traveler. You successfully terrified an innocent person about the future without mentioning the name Donald Trump or Hillary Clinton. But we seasoned veterans of the 2016 season are able to accept those facts as true. Over the past 30 days, Bryce Harper (.289 wOBA) and Ben Revere (.287 wOBA) have been equivalently awful for the Nationals and, yet, the team is on an offensive tear. As you might expect, it’s been necessary for a lot of different players to perform well in order to make up for Harper’s lack of production – Wilson Ramos and Daniel Murphy have hit well all season while Danny Espinosa and Jayson Werth have recently turned their early season struggles around – but the biggest contributor for the Nationals at the plate of late has been Anthony Rendon.

Through May 9th, Rendon had hit a dismal .211/.289/.297, a line which amounted to offensive production nearly 40% below league average. Coming off a disappointing and injury-plagued 2015 season, it was natural to start wondering whether the 2014 season which led to him finishing fifth place in MVP voting was a flash in the pan never to be seen again. But then, Rendon started hitting. He entered play last night with a .324/.411/.546 line since the cherry-picked date of May 9th. This offensive outburst has raised his full-season wRC+ to a perfectly respectable 107.

Although the May 9th dividing line is arbitrary, it does come close to splitting his season in half, with 142 of his plate appearance coming before this magical date and 128 coming after. Let’s keep using this convenient dividing line to help us take a look at a key change in Rendon’s approach — one which may help explain his recent offensive outburst.

The Fastballs Abandoned Michael Conforto

There’s a funny thing about this line of work. We have access to information, so much information, an increasing amount of information, and it allows us to break down almost every single aspect of player performance. Want to know how a pitcher’s fastball has moved? Easy. Want to know where a batter hits groundballs against sliders? No problem. Interested in where outfielders are positioned with a lefty spray hitter at the plate? That’s becoming possible. So much is possible. An incredible amount is possible. Yet we still don’t know anything about what’s most important. If a player is locked in, he stands a chance. If he’s preoccupied, because, say, he got in an argument, or he thinks he left the oven on, he’s probably going to struggle, for no visible reason. You’re worse at what you do when you’re distracted, or when you’re frustrated. There aren’t any numbers for that.

Michael Conforto is in a slump. It’s a bad one, too, and Conforto feels it, and it happens to be taking place when the Mets are somewhat desperate for offense. That doesn’t help the stress, and maybe stress is the real problem. In baseball terms, he could be pressing. There’s no way for us to analyze that. What we can say for sure: In April, Conforto was the second-most productive hitter in the game. Granted, he was behind only Aledmys Diaz, so, April is weird. But since then, the wRC+ has dropped to 42. He’s struck out almost a third of the time. He’s chasing. The Mets don’t think it’s anything mechanical, and they’re prepared to let Conforto play out of this. I assume, at some point, he will. That doesn’t help the slump today. Conforto still feels the weight of his responsibility.

Effectively Wild Episode 904: The Big Baseball Grab Bag

Ben and Sam banter about a wide range of topics, including Ray Searage and the struggling Pirates pitching staff; the pitcher home run derby; rehabilitating Ben Cherington; the amazing Matt Shoemaker; Clayton Kershaw; crowd chants, and a bad fun fact.


Hitter Contact-Quality Report: First Base and DH

Over the last couple of weeks, we’ve taken a look at the 2016 contact management ability of ERA-qualifying starting pitchers in both leagues, utilizing granular batted-ball data. Now it’s the hitters’ turn. Over the next few weeks, we’ll take a position-by-position look at hitters’ contact quality, using exit speed, launch angle, and BIP type frequencies as our tools. Today, let’s look at each team’s primary first basemen and designated hitters.

A Brewers Prospect and His Law School Application

Just over a month ago, I led one of my Sunday Notes columns with Jon Perrin and his microscopic walk rate. At the time, the 22-year-old Milwaukee Brewers prospect had issued just one free pass in 36 innings. He had 47 strikeouts.

A few days later, Perrin was promoted from Low-A Wisconsin to High-A Brevard County. His numbers with the Manatees aren’t quite as eye-popping, but they’re still impressive. On the season, Perrin has now issued seven walks over 71 innings. The Oklahoma State alum has 77 strikeouts and a 2.66 ERA between the two stops.

His numbers were only part of the story. An aspiring attorney, Perrin had taken the LSAT and was awaiting word on a law school application. Despite his success on the diamond, he was possibly going to be hanging up the spikes.

As Perrin put it in May, “If I get into Harvard, I’m probably going to be out of here. I love the game, but I think I can do more good in this world with a degree from Harvard Law School than I ever could playing baseball.”

He’ll have to settle for baseball (at least for now). Perrin learned earlier today that he wasn’t accepted at Harvard Law.


Xander Bogaerts Changes, Really Remains the Same

Everything Xander Bogaerts did well in his breakout season last year, he seems to be doing better this year. More power, more patience, more contact, and better defense — he’s basically equaled last year’s full-season WAR figure already, and there’s three-fifths of a season left to go. He’s leading the league right now!

Of course, WAR isn’t your traditional counting stat: Bogaerts could hypothetically put up negative wins going forward, were he to regress in one way or all of them. But since he gave us such a great preview last year, it’s tempting to believe in all of the improvements he’s made. He’s really the same guy, just a little better.

At the center of his improvement has been how hard he hits the ball, the angles (both vertical and horizontal) of those batted balls, and his defensive range. He didn’t think much had changed about those particilar variables when I asked him, though. Just a few minor tweaks.

Another Thing at Which These Cubs Are Best

Just as a recap, here’s some things at which the Cubs have proven to be among the best this year. They’ve been among the best at getting fans to the stadium. They’ve been the best at not pitching to Bryce Harper. They’ve been the best at drawing walks (perhaps that we’ve ever seen), and they’ve been the best base-running team. Basically, they’ve looked like the perfect baseball team. Maybe this seems like overkill, all the Cubs posts already and another one here right now. Or maybe they’re just deserving of all these posts, on account of how dominant and unique they’ve been thus far. I’d argue the latter, but I know that’s not a unanimous opinion.

Either way, here comes another Cubs post! There’s another record they’re pursuing, but it’s not a particularly sexy record, nor is it one that necessarily indicates skill and skill only. Definitely some skill involved, but it’s the kind of record where you’re not too sure how to feel about it, or what, exactly, it means. Even right now, the Cubs are doing this thing, and I’m not totally sure what to make of it. That’s what this post is for!

Is Salvador Perez Turning On the Power?

We’re given a few things. One, Salvador Perez is rather newly 26 years old. And he’s a catcher, and you know how they develop. Two, Perez is running what would be a career-high strikeout rate. Three, Perez is running what would be a career-high isolated slugging. We’ve seen this before, and the speculation is almost always the same. Is Perez starting to trade some of his contact for power? He wouldn’t be the first to go down that path, even if it seems like a particularly anti-Royals thing to do.

By no means has Perez been powerless in the past. Last year he socked 21 dingers! The year before, 17 dingers. The year before that, 13 dingers. But there could be more in there, and there’s no ignoring the signs. I’m not coming up with things out of the blue; I’m just following the evidence. And now, here, have some more evidence. Using Baseball Savant, I looked at all the hitters who had at least 100 batted balls tracked in both 2015 and 2016. I calculated the changes in average exit velocity and average launch angle, and then I used some simple math to find the biggest overall changers. Here are the top five, in the more-power direction. These guys have hit the ball harder, or lifted the ball more, or both.

Batted-Ball Changes
Hitter Change, MPH Change, Angle
Danny Espinosa 4.7 3.8
Salvador Perez 3.4 6.1
Jose Altuve 3.8 2.4
Odubel Herrera 0.9 7.8
Freddy Galvis 3.4 2.1
SOURCE: Baseball Savant

Based on z-scores, Espinosa is up a combined 3.8, while Perez is up a combined 3.7. So maybe this could just as easily be a post about Danny Espinosa, but Perez is more interesting to me. With a batted-ball-speed increase of 3.4 miles per hour, Perez ranks fifth-best in the pool. And with a launch angle that’s increased by 6.1 degrees, Perez ranks seventh-largest in the pool. Having both things happening at once points in a direction, and that’s backed up by the increase in strikeouts. It’s not at all certain, but on appearances, Salvador Perez seems to be less of a contact hitter, and more of an extra-base-hit hitter. And after posting consecutive sub-100 wRC+ marks, he’s presently up at 120. He’s already cleared last year’s overall WAR.

This is an InstaGraphs entry, so I’m afraid I don’t have anything else. I’m going to monitor Perez for longer before I go into more detail. It’s always fascinating when a bat elects to begin a new chapter. That’s what it looks like Perez is doing, and though it could just be a fluke, it could also be the next stage of development for a potential franchise icon. The Royals have always loved Perez, from the beginning. It’s been easy to forget he wasn’t a finished product.
