KATOH on the Cape: Projecting Cape Cod League Pitchers

Last Tuesday, I published a post examining the hitters in this year’s Cape Cod summer league through the lens of my KATOH projection system. Today, I’m back to look at the pitchers. As I did with minor-league players and college players, I deployed a series of probit regressions to see what stuck when it came to forecasting major-league performance for Cape League players. I used those results to generate an expected WAR total — in this case, through age 28. These projections are far from gospel: scouting the stat line is always dangerous, and it’s even more dangerous than usual at the college level, where the samples are small, the players are raw, and the quality of opposing pitching runs the gamut. Nonetheless, statistical performance is an often overlooked component of prospect evaluation, and the performers often go on to exceed expectations.

A couple of caveats. Due to the poor quality of publicly available historical summer-league data, these projections do not directly account for pitchers’ home-run rates, which is obviously less than ideal. Secondly, these projections take into account only what these players have done this summer. Ideally, they’d account for college stats and summer-league stats. I do plan to link these two data sets at some point, but, unfortunately, it’s easier said than done.

Below, you’ll find a few notes on performances whom I deemed noteworthy. Below that, you’ll find a giant table for all hitters who recorded at least 75 batters faced (BFs) in the Cape Cod League this year. The two rightmost columns refers to each prospect’s ranking on Baseball America’s Cape Cod top-30 list and Frankie Piliere’s top-150 list from D1 Baseball.

The Remarkable First Year of Corey Seager

While the 2016 season has a month left to go, over the weekend, Corey Seager completed his first full year in the big leagues. He was called up to the majors on September 3rd of 2015, so he’s now spent a little more than 365 days as a Major League player, and has played almost exactly one full big league season. And it is hard to imagine how it could have gone much better.

Corey Seager’s First Year
G PA BA OBP SLG wRC+ UZR BSR WAR
160 697 0.319 0.385 0.539 151 8.8 2.3 8.5

Since the day he got to the big leagues, Seager has performed like an upper-tier superstar. Over the last calendar year, his +8.4 WAR ranks third-best in baseball, behind only Mike Trout (+10.1) and Kris Bryant (+9.0), and as he’s played at an MVP-level since arriving in Los Angeles. He might not be as elite an athlete as Trout or even more-heralded young shortstops like Carlos Correa, but he’s shown the kinds of bat-to-ball skills that make for pretty special hitters.

The Case for Jose Altuve for American League MVP

This week, we’re going to run a series of posts laying out the case for the most compelling candidates for the American League’s Most Valuable Player Award. These posts are designed to make an affirmative argument for their subject and are not intended to serve as comprehensive looks at every candidate on their own. The authors tasked with writing these posts may not even believe their subject actually deserves to win, but they were brave enough to make the case anyway. The goal of these posts is to lay out the potential reasons for voters to consider a variety of candidates and to allow the readers to decide which argument is most persuasive.

Other cases: Mike Trout for AL MVP.

Mike Trout leads the American League in every major calculation of WAR: Baseball Prospectus’ version, Baseball-Reference’s version and our very own version right here at good ol’ FanGraphs. This unsurprising fact is true because the guy is so damn good at every aspect of baseball. He gets on base. He hits for power. He’s a shockingly productive base-runner. The only area in which he lags a bit is in defensive value, but his offense puts him so far above the competition that no one can surpass Mike Trout’s overall production on the field right now.

That said, let me tell you why Mike Trout isn’t the Most Valuable Player in the American League.

It’s not an easy argument to make. Sure, numbers can be manipulated but not to a degree that allows a straight-up objective argument for any American League player being better than Trout. Comparable? Perhaps. But better? That argument doesn’t exist. We’re here at FanGraphs because we like numbers and objective truths — and all of those indicators point to Mike Trout as the best player in the American League this season. But… I can’t believe I’m about to write these words in this cliché order… let’s talk about the meaning of the word valuable. I think there’s a remarkably valid interpretation of that word which makes this year’s most deserving AL Most Valuable Player candidate a diminutive second baseman from Houston.

How Brian Dozier Put Together a Season for the Ages

Yes, it’s true that this is the year of the second baseman. As a group, second basemen are putting up better offensive numbers than they have in nearly a century, and are outhitting their defensively challenged counterparts in left field for the first time in the history of the live-ball era, dating back to 1920. And yes, it’s true that power across the sport is nearly at an all-time high. The league’s power output has returned to peak steroid-era levels, with this year’s isolated slugging percentage and home runs per plate appearance trailing only the year 2000 as the most power-laden season in the game’s history.

Those trends are real, and they should help shape the way we evaluate hitter’s performances in 2016. But don’t let those trends fool you: Brian Dozier is truly having a season for the ages.

The Minnesota Twins’ second baseman clubbed three home runs against Kansas City on Monday afternoon, bringing his season total to 38. Only Mark Trumbo has hit more homers than Dozier for the season; only David Ortiz has a higher ISO. Dozier’s homered eight times in the last week and has been baseball’s most valuable player in the second half according to WAR. His .298 ISO is the highest unadjusted figure in the expansion era (1961-present) for a second baseman and the highest by any second baseman not named Rogers Hornsby in baseball history.

The Case for Mike Trout for American League MVP

This week, we’re going to run a series of posts laying out the case for the most compelling candidates for the American League’s Most Valuable Player Award. These posts are designed to make an affirmative argument for their subject and are not intended to serve as comprehensive looks at every candidate on their own. The authors tasked with writing these posts may not even believe their subject actually deserves to win, but they were brave enough to make the case anyway. The goal of these posts is to lay out the potential reasons for voters to consider a variety of candidates and to allow the readers to decide which argument is most persuasive.

Two-and-a-half months from now, after the World Series is over and clubs are in full offseason mode, the BBWAA will announce its end-of-season awards winners live on MLB Network. Given the way the public conversation is going and the way voters have traditionally cast their ballots, it appears likely that someone other than Mike Trout will win the American League’s Most Valuable Player honors.

The MVP award traditionally goes to the best hitter on a playoff team. It’s not a hard-and-fast rule, but it’s been 13 years since a player won the AL MVP award without making the playoffs, and only one pitcher has won since the strike. Not every BBWAA writer believes in this particular definition of MVP, but enough of the population does to ensure its continued observance. National League voters have been a little more forgiving about making the playoffs, but Trout doesn’t play in the NL.

The Angels are not going to make the playoffs even if they win all of their remaining games, so Trout’s odds of actually winning the award are minimal. Unless the group of writers chosen to vote for AL MVP this year is particularly unrepresentative of the BBWAA as a whole, someone like Josh Donaldson or Mookie Betts will win. Donaldson and Betts have had excellent seasons and should be recognized for their performance, but if you apply any reasonable criteria beyond team performance, Mike Trout should be the AL MVP.

Building a Top-50 Priority List for MLB.TV Game Changer

Last week, Ben Lindbergh wrote a piece titled “Baseball Has a ‘RedZone’ Channel” over at The Ringer. It was all about a script that Dan Hirsch wrote at The Baseball Gauge called MLB.TV Game Changer. Basically, if you’re watching MLB.TV in a web browser, this script will allow you to program your MLB.TV experience to skip to the action that you most want to see, and you can customize it in many different ways. Put succinctly, this blew my mind. So I spent the better part of a night playing with the script’s priority list.

NERD Game Scores for Monday, September 05, 2016

Devised originally in response to a challenge issued by sabermetric nobleman Rob Neyer, and expanded at the request of nobody, NERD scores represent an attempt to summarize in one number (and on a scale of 0-10) the likely aesthetic appeal or watchability, for the learned fan, of a player or team or game. Read more about the components of and formulae for NERD scores here.

Most Highly Rated Game
Toronto at New York AL | 20:10 ET
Dickey (160.1 IP, 112 xFIP-) vs. Tanaka (173.0 IP, 82 xFIP-)
By whatever method one uses to determine such a thing, the result seems largely the same: the Toronto Blue Jays possess roughly a 50% probability of winning the AL East and something slightly less than that of qualifying for an AL wild-card spot and something less than either of those first two figures of failing to reach the postseason in any form, at all. But even that last figure is probably greater than 10% — which, events that are 10% likely to occur, they occur with some frequency. Like that someone would write these banal words, for example. And like that someone would consent to read them.

NERD Game Scores: Jose De Leon Debut Event

Most Highly Rated Game
San Diego at Los Angeles NL | 16:10 ET
Friedrich (100.1 IP, 120 xFIP-) vs. De Leon (MLB Debut)
The author has abused his role as the custodian of this daily post to assign — at his awful discretion — a NERD score of 15 to Dodgers pitcher Jose De Leon, thus rendering the game score one of the day’s highest. The reason: today’s start represents De Leon’s first as a major leaguer. And also the reason: basically no minor-league pitcher has matched De Leon’s success over the past few years. Consider, by way of example: at no point since Rookie ball in 2013 has De Leon recorded a strikeout rate below 30%, even while working almost exclusively as a starter. Nor does the success appear to be a product of mere deception or polish. Basically all public accounts report that the right-hander’s fastball sits at 92-94 mph. By comparison, the average four-seam fastball velocity among major-league starters this year has been 92.0 mph.

Here is not De Leon’s fastball, but rather his changeup, earning a swing and miss from Jake Lamb during spring training:

Sunday Notes: Richie Martin, Miller’s HRs, Gordon, Twins, more

Richie Martin grew up in Tampa and plays in the Oakland A’s organization, but he has a lot of Detroit in him. The 21-year-old shortstop prospect was born in the Motor City and still has family there. There are baseball connections. Martin’s 74-year-old father was a high school teammate of Tigers legend Willie Horton — the two remain friends — and the youngster considers Chet Lemon a huge influence and “almost a second dad.”

Martin — the 20th-overall pick in the 2015 draft —played youth baseball for Lemon beginning when he was 12 years old. Not surprisingly, he’s friendly with the former centerfielder’s son, Marcus Lemon, who plays in the White Sox system. The two share more in common that athletic talent. Both are creative.
