Watching all-time great baseball players age is both a frustrating and fascinating experience. Albert Pujols will never be able to recapture the dominance that gave him one of the greatest first decades in MLB history, as the aging process is unkind and irreversible. Even Barry Bonds with his late-career surge into the record books was a much different player than he was earlier in his career. Albert Pujols has seen something of a revival in 2015, hitting his American League-leading 21st home run of the season on Sunday. The 35-year old Pujols will never be able to get back to the form he had a decade ago, but he is hitting better than he has at any time in an Angels uniform.

With 10 home runs in June, Pujols already has his first double-digit home-run month since August 2010, when he hit 11 homers. His 149 wRC+ is higher than his final season in St. Louis, although the season did not begin as Pujols would have liked. After going 0-for-4 with a strikeout against the Rangers on April 24, Pujols was hitting just .177/.261/.355 in 69 plate appearances. In the 210 plate appearances since, Pujols has been on a tear, hitting .301/.352/.622 with a 173 wRC+ providing Mike Trout a worthy partner in an otherwise punchless Angels’ offense.

It has been almost exactly two years since the Red Sox made high-school left-hander Trey Ball the seventh-overall pick in the 2013 draft, the first southpaw off the board. Needless to say, such a high selection comes with considerable fanfare and attendant expectations. Soon after being drafted, most Red Sox prospect lists included Ball somewhere in the top 10 (in a stacked organization), and he even snuck into the back end of a few overall top 100s. He did sign for under slot, and as a lanky, projectable high-school arm, he wasn’t exactly expected to move quickly, but still, Ball has spent his career at least largely under the microscope.

Now under a month from his 21st birthday, though, Ball has done little to inspire significant praise since his selection. In 175.2 career innings, he has struck out 115, walked 75, allowed 18 home runs, and posted a 4.41 ERA. He ranked just 15th on Kiley’s offseason Red Sox prospect list, and that wasn’t far off his typical placement. Nobody’s written Ball off as a bust, but nobody has thrown future ace plaudits at him as a pro, either. Oddly, he seems to be almost flying under the radar, as others in Boston’s system have attracted more attention at various points in the past two seasons.

Ball nevertheless remains an important figure in the Boston system, and he’s at the point in his career where it’s time to start examining the present and future of his development. I caught his start on May 29, and it definitely gave a better sense of why Ball hasn’t taken the minors by storm yet, as well as how he projects going forward.

On late Saturday night, the Diamondbacks and Braves made a trade, but while players were sent in both directions, this was really more of just a sale. Sure, the Braves did give up a player — replacement-level utility guy Phil Gosselin, currently on the DL — in the swap, but they traded Gosselin for a legitimate prospect and a Major League pitcher, which only makes sense when you add in the financial aspects of the deal. In taking on the remainder of Bronson Arroyo’s salary — roughly $10 million, including the buy-out of his 2016 option — the Braves essentially bought pitching prospect Touki Toussaint from the Diamondbacks for that $10 million figure.

While this isn’t an entirely new type of trade — the Dodgers essentially did this same thing a few months ago when they bought a draft pick from the Orioles by taking Ryan Webb off their hands — it’s still a little unusual to see a team make a trade that can so clearly be broken down as a legitimate asset for just straight cash. And in this case, it’s made even more unusual because the team selling the prospect is in rebuilding mode, so we have an organization focused on the future selling an asset with future value in exchange for short-term financial relief.

But it shouldn’t be a big surprise that the team doing the unexpected is the Diamondbacks, who have been marching to the beat of their own drum ever since Tony La Russa and Dave Stewart took over. The D’Backs don’t operate like the other 29 franchises do, and they don’t see things like everyone else, so they make moves that cause a lot of heads to be scratched. This move is no different, with the trade drawing near total criticism from Arizona’s perspective. At its heart, though, this is simply a question of how to value an A-ball pitching prospect, so let’s break this down and see if the D’Backs really did get fleeced on this deal.

On Friday, Ken Rosenthal of Fox Sports wrote an article titled “Red Sox need to dump Sandoval, Ramirez, like, now.” He states, in essence, that the Red Sox need to dump Pablo Sandoval and Hanley Ramirez, like, now. He states that they’re bad fits for Boston and that the Red Sox should have known that and the only way forward for Boston is to send both elsewhere and pay whatever it costs to do so. Suppose the Red Sox did trade Sandoval and Ramirez. Suppose they followed Rosenthal’s plan and got rid of both. What would happen then? Would Boston be better off? Let’s find out!

Kershaw (93.0 IP, 57 xFIP-) vs. Wada (29.1 IP, 94 xFIP-)
In his collection of aphorisms The Trouble with Being Born, the spiritually embattled and now also dead Romanian philosopher Emil Cioran writes “The more gifted a man is, the less progress he makes on the spiritual level. Talent is an obstacle to the inner life.” Granting, for a moment, the truth of Cioran’s utterance, one is compelled to reason that left-hander Clayton Kershaw lacks much in the way of said inner life — owing, that is, to the flagrancy of his talents. This season, for example, he’s produced thus far both the highest swinging-strike and also overall strikeout rate of his career. Also, somehow, his average fastball velocity remains largely identical to the figures he recorded over each of the past seven years — this, despite the fact that pitchers as a population tend to lose about 0.3 to 0.5 mph each year. Empty, is what he must be on the inside. Empty and hollow. Like a big human kettledrum.

For the introductory, less math-y post that explains more about what this project is, click here.

The concept of reliability comes from the classical test theory designed for psychological, research, and educational tests. The classical test theory uses the model of a true score, error (or noise) and observed score. [2]

To adapt this to baseball, the true “score” would be the true talent level we are seeking to find, and observed “score” is the actual production of a player. Unfortunately, the true talent level can’t be directly measured. There are several methods to estimate true talent by accounting for different factors. This is, to an extent, what projection systems try to do. For our purposes we are defining the true talent level as the actual talent level and not the value the player provides adjusted to park, competition, etc. The observed score is easy to measure, of course — it’s the recorded outcomes from the games the player in question has played. It’s the stat you see on our leaderboards.

The error term contains everything that can affect cause a discrepancy between the true score and the observed score. It contains almost everything that affects the observed outcome in the stat: weather, pitcher, defenses, park factors, injuries, and so on. This analysis isn’t interested in accounting for those factors but rather measuring the noise those factors in aggregate impart to our observed stat.

INTRODUCTION

“Small sample size” is a phrase often used throughout the baseball season when analysts and fans alike discuss player’s statistics. Every fan, to some extent, has an idea of what a small sample size is, even if they don’t know it by name: a player who goes 2-for-4 in a game is not a .500 hitter; a reliever who hasn’t allowed a run by April 10 is not a zero-ERA pitcher. Knowing what small sample size means is easy. The question is, though, when do samples stop becoming small and start becoming useful and meaningful?

Research by the Washington Post’s Christopher Ingraham — summarized in the graph below — reveals that Google searches for the term “hangover cure” are most frequent on Sundays.

Insofar as today is Sunday, it follows that a certain percentage of this site’s readers are experiencing la gueule de bois. While this afternoon’s encounter between the Tigers and Yankees doesn’t represent an actual hangover cure, it ought to serve — more than any other of the day’s games, according to the haphazard methodology utilized by the author — as a reasonable means of passing the time.
