Last Season’s Most Underrated Rookie

I got to participate in the voting for last season’s American League Rookie of the Year award. Like almost everyone else, I agonized over whether to go with Gary Sanchez or Michael Fulmer, before ultimately settling on the latter. Tyler Naquin rounded out my ballot. It was the most common ballot — there were a dozen, out of 30, that read like mine.

If I had a fourth-place slot, I would’ve found room for Christopher Devenski. As is, Devenski showed up on five ballots, finishing third on four and second on one. There were many rookies last year who were pretty good. Devenski, somehow, has seemingly flown under the radar. He was so good!

If I wanted, I could leave it at this — there were 142 different pitchers in all of baseball who threw at least 100 innings. Here are the best of them, by ERA-:

  1. Clayton Kershaw, 43
  2. Kyle Hendricks, 51
  3. Chris Devenski, 52

But you could look at the fact that Devenski allowed just four homers and conclude he got lucky. He probably did. Doesn’t mean he didn’t get better and better. It’s Devenski’s second half that really stands out. After the All-Star break, he threw 49.2 innings. Here are some percentile rankings out of everyone who cleared 25 post-ASB frames.

Down the stretch, Devenski threw strikes like Max Scherzer, and he missed bats like…well, also Max Scherzer. He compelled hitters to constantly chase out of the zone, in part a testament to his outstanding changeup. But you shouldn’t come away believing Devenski was some kind of soft-tosser; by September he was throwing his average fastball around 94 miles per hour.

Devenski was underrated because he wasn’t really a starting pitcher. He did start a few times, but he predominantly relieved, without closing. As you know, statistically speaking, relievers have it easier. Yet Devenski wasn’t a reliever of the conventional sort. The last bar in the plot above reads PA/GR. That’s out of a different sample pool — all relievers with at least 10 appearances in the second half. The category itself refers to average plate appearances per relief appearance. Devenski was close to the top. He wasn’t a matchup guy, or a one-inning guy. He was more of a multi-inning swingman, which makes his numbers all the more remarkable. He was that good, for dozens of pitches at a time.

Borrowing from Texas Leaguers, Devenski made a midseason change that could’ve driven his greater success.

As the season wore on, Devenski all but abandoned his curveball, replacing it with a sharper slider. He showed excellent command of the pitch, and opponents missed it nearly half of the time they swung. Here’s Devenski using the slider to get back in the count:

The slider gave Devenski a consistent third pitch. In the second half, he threw it 22% of the time. He threw his fastball 40% of the time. And he threw his changeup — this changeup — 32% of the time.

Lefties would see all three pitches. Righties would see all three pitches. And Devenski’s over-the-top delivery presumably added some measure of deception. His fastball comes with a good amount of rise, and the changeup plays off of it perfectly. The slider is why the Astros are still thinking about Devenski as potentially becoming a starter. He might work well for five or six innings at a time. It’s already clear he can work well for two or three.

Devenski is going to be a key part of the Astros’ enviable pitching depth, no matter his role. Whether he’s rotation insurance or a steady presence in the bullpen, he’ll provide something every manager wants. As he showed over last season’s final three months, he can pitch as well as almost anyone else, and this from someone who was a completely unheralded prospect. A 25th-round draft pick who was included as a PTBNL for Brett Myers. You can give the White Sox some credit for identifying and developing Jose Quintana. In a similar but opposite way, I guess Devenski was an oversight.

Podcast Results: The Over/Under Game with Dave Cameron

Last week, the author of this post played the inaugural Over/Under Prospect Game on FanGraphs Audio with lead prospect analyst Eric Longenhagen, the results of which contest were subsequently recorded for posterity at this site. Now, just this very minute, the same author has published an audio record of a similar game — in this case with managing editor Dave Cameron.

The rules of this particular version:

  • Contestant A introduces a specific metric for 2017.
  • Contestant A proposes a precise figure for that metric.
  • Contestant B chooses the over or under.

So, for example: in this edition of the game, Cameron proposes a wager concerning Adam Eaton’s UZR figure in center field for the Nats this season. He sets the over/under mark at +8.0 runs. The author of this post chooses the under. Bet made.

Each Cameron and the host submit five over/under proposals in this episode, for a total of 10 overall. The results of all 10 wagers appear below.

Wager No. 1
Contestant A: Cistulli
Metric: Games entered by Andrew Miller in 7th inning or earlier.
Over/Under: 22
Contestant B: Cameron
Chooses: Under

The Least Intimidating Hitter in Baseball

You can learn a lot about a hitter by the way he gets pitched to. Granted, you can also learn a lot about a hitter by the way that he hits, but when you look at the approach, you learn something about perception. You learn how opponents see the hitter. Two useful measures: fastball rate, and zone rate. You could of course go deeper than this, but fastball rate tells you something about fear. The same goes for zone rate. If someone keeps getting fastballs in the zone, the pitchers probably aren’t afraid. If someone rarely sees fastballs or pitches in the zone, well, something else is going on.

Some 2016 numbers, for reference:

Fastball and Zone Rates
Split Fastball% Zone%
Pitchers 71% 55%
Non-Pitchers 56% 48%
Top 25 ISO 53% 45%
Bottom 25 ISO 59% 49%

You can see how aggressively pitchers are attacked by other pitchers. The fastball rate skyrockets, and you get five out of nine pitches in the strike zone. More powerful hitters see fewer fastballs, and fewer strikes. Less powerful hitters see more fastballs, and more strikes. This is all easy and intuitive, and although there are other variables to consider, we’ve touched on the big stuff.

Using these statistics, we can attempt to quantify a hitter’s intimidation. No, it’s not perfect, but I’ve still run the math, calculating z-scores for both of the rates. The last step is just adding the two z-scores together. In this table, the least intimidating hitters in baseball in 2016, given a minimum of 200 plate appearances.

Least Intimidating Hitters, 2016
Player Season Fastball%, z Zone%, z Combined
Ben Revere 2016 3.5 1.9 5.3
Nori Aoki 2016 1.8 2.6 4.4
J.B. Shuck 2016 1.9 2.1 4.0
Billy Burns 2016 1.2 2.7 3.9
Shawn O’Malley 2016 1.9 1.9 3.8
J.J. Hardy 2016 1.5 2.2 3.7
Angel Pagan 2016 2.6 0.9 3.5
DJ LeMahieu 2016 2.3 1.0 3.3
Darwin Barney 2016 1.3 1.9 3.2
Derek Norris 2016 1.6 1.6 3.2

It’s Ben Revere! And it’s Ben Revere by a mile. Revere just saw 70% fastballs, and he saw 52% of all pitches in the strike zone. That’s not quite where pitchers wound up, collectively, but Revere was nearly pitched like a pitcher, and that certainly sends a message. No one was afraid of him, and not coincidentally, Revere finished with a 47 wRC+. He did, though, smack a couple of dingers.

For some context, I calculated numbers for individual hitter-seasons throughout the PITCHf/x era, stretching back to 2008. Where did Revere’s season rank in terms of its unintimidatingness?

Least Intimidating Hitters, 2008 – 2016
Player Season Fastball%, z Zone%, z Combined
David Eckstein 2009 3.1 2.7 5.8
David Eckstein 2010 3.1 2.5 5.6
Marco Scutaro 2013 2.6 2.9 5.5
Nick Punto 2013 2.8 2.7 5.5
Ben Revere 2016 3.5 1.9 5.3
Jason Kendall 2010 2.8 2.5 5.3
David Eckstein 2008 2.8 2.2 5.1
Denard Span 2011 2.0 3.0 5.0
Ryan Hanigan 2015 1.9 3.0 4.9
A.J. Ellis 2015 3.0 1.9 4.9

Not a bad showing — fifth place, out of 3,148 hitter-seasons. David Eckstein occupies the top two spots, and, sure, of course he does. Because I’m sure you’d wonder, the lowest combined score is -6.7, belonging to 2012 Josh Hamilton. Pitchers definitely didn’t want to throw him any fastballs, and they didn’t want to risk anything he’d find particularly hittable.

Back to Revere. There was an article on Nationals.com after the home run embedded above, which was Revere’s first of the season. Said Dusty Baker, unironically, or maybe ironically, how should I know:

“I’m just hoping he doesn’t get that dreadful disease of home run-itis,” Baker said.

Said Revere, referring to same:

“If I try to hit it in the air, I’ll probably be at .250 or a Mendoza-line .200 hitter. But if I hit the ball on the ground or line drives, I’ll be .300 for a long time.”

Revere ran the same ground-ball rate he had as a regular in 2015, when he hit .306. He finished the year batting .217.


The Reinvention of Franklin Gutierrez, Baseball Miracle

The Dodgers signed Franklin Gutierrez over the weekend. Now, I didn’t realize the Dodgers still had room on their major-league roster, but they probably know better than I do. Here is a list of problems that have sent Franklin Gutierrez to the disabled list over the past several years:

  • stomach gastritis
  • strained left oblique
  • torn right pectoral
  • concussion
  • strained right hamstring
  • strained right hamstring

Related to the above, here are Gutierrez’s year-to-year plate-appearance totals after getting traded to the Mariners:

  • 2009: 629
  • 2010: 629
  • 2011: 344
  • 2012: 163
  • 2013: 151
  • 2014: 0

That zero stands out. Gutierrez missed all of 2014, making the personal decision to sit out so he could focus on treatment. Treatment for what? Treatment for ankylosing spondylitis! Young athletes are not often diagnosed with ankylosing spondylitis, but Gutierrez was, and there isn’t a cure. It’s a condition he’ll deal with for the rest of his life, and it costs him flexibility and mobility. It’s cruel and unrelenting, and when Gutierrez elected to not play, he couldn’t have known whether he’d ever be able to return.

But he tried in 2015. He tried, and he succeeded, having settled on a treatment plan that left him feeling somewhat okay. Gutierrez batted almost 200 times with the 2015 Mariners, and then he batted almost 300 times with the 2016 Mariners. And the player that Gutierrez turned himself into was and is dramatically different from the player he’d been before.

Franklin Gutierrez vs. Franklin Gutierrez
Years PA Def/600 BB% K% wRC+ ISO HR/FB% Hard% Zone% WAR/600
2007 – 2010 1999 18.3 7% 21% 94 0.143 9% 32% 53% 3.6
2015 – 2016 472 -10.3 9% 29% 135 0.255 30% 44% 45% 3.7

That’s a comparison of recent Gutierrez to what’s basically peak, healthy Gutierrez. Earlier in his career, Gutierrez was as smooth an outfield defender as anyone had ever seen. He was one of the best defensive players in baseball, and at the plate, he showed some promising pop. Now look at the last two years. Gutierrez has become a negative defensive asset, because he simply doesn’t move so well anymore. For the same reason, he’s seldom aggressive on the bases. So much of that old athleticism is gone, and it’ll never return. But Gutierrez has found a way to compensate. He’s gotten bigger, and he’s made a conscious effort to try to just beat the living crap out of the ball.

Some percentile rankings from the last two years:

  • HR/FB%: 100th
  • ISO: 96th
  • Hard%: 99th
  • wFA/C: 99th
  • Exit Velo: 96th
  • Contact: 7th
  • K%: 5th
  • Fastball%: 4th
  • Def/600: 19th

No hitter in baseball has managed a higher rate of home runs per fly ball. Gutierrez has some of the best hard-contact measures around, having sacrificed contact to get there. At this point, he has a lot of power and a lot of swing-and-miss, and so pitchers increasingly treat Gutierrez like a terrifying threat, avoiding fastballs and avoiding the zone. As far as other things go, Gutierrez can still play the outfield, but he isn’t very good at it. And there will be days he’ll wake up and he simply won’t be able to play. On those days, his condition won’t let him.

The reality is, Gutierrez isn’t getting healthier. And teams are reluctant to sign a player whose availability is unpredictable. From time to time, the Dodgers might end up frustrated, playing games with a short bench. But they know what they’re getting into, and they know what Gutierrez has been able to do since his return. Having lost a lot of his ability to move around, Gutierrez has focused on more light jogs and fewer hard sprints. He remains active with his 34th birthday coming next week, and given where he’s been, that’s almost impossible to believe.

Where Chris Archer and Max Scherzer Were Opposites

Late last week, I published an article about Kevin Kiermaier, calling him further underrated because he’s faced an abnormally tough schedule of opposing pitchers. On the other side of things, Jorge Soler is coming off a year in which he faced one of the easiest opposing slates in recent history. This doesn’t lead to anything conclusively — worse pitchers can throw great pitches, and great pitchers can make mistakes. But what’s suggested is that Kiermaier’s true talent is higher than his numbers, while Soler probably had his 2016 stats inflated. This is an adjustment we so infrequently discuss.

If I’m going to point to hitters and their strengths of schedule, it only makes sense to look at pitchers, too. So I did that for a number of pitchers in 2016, guided by this Baseball Prospectus list. I didn’t calculate numbers for every pitcher, but I examined many pitchers at either end of the BP list. All I did was calculate the average 2016 wRC+ posted by the pitchers’ opponents. The higher the number, the tougher the average opponent. The league-average wRC+ last season, with pitchers included, was 97.

Pitchers with easier schedules

For the most part, I just wanted to look at pitchers who threw at least 100 innings. But for some smaller-sample fun, J.P. Howell’s average opponent managed just an 84 wRC+, while Matt Harvey wound up at 85. That makes Harvey’s season look only worse, although he had a pretty good reason for that.

Pitchers with tougher schedules

The gaps might not seem that big to you, I don’t really know. But for whatever it’s worth, Todd Frazier just had a 102 wRC+, and Adonis Garcia finished at 90. Steamer projects Mike Napoli for a 103 wRC+, with Kevin Pillar at 90. Imagine the difference between a full season facing lineups of Napolis and lineups of Pillars. Mathematically, it would work out to double-digit runs, so just remember this the next time you’re, say, recalling some pitching numbers from the 2016 American League East. Not every schedule is created the same, and you better believe certain pitchers can feel it.


(Still) The Most Volatile Hitter in Baseball History

Last week, on Twitter, Mike Petriello reminded me that, in January of 2016, I wrote a post entitled The Most Volatile Hitter in Baseball History. The headline was sexy and interesting, because I didn’t know any other way to convince you to read a post about Ryan Raburn. The gist: I looked at all four-year season stretches dating back to 1900, with at least 200 plate appearances in each season. Raburn, over his four-year span beginning in 2012, had seen his wRC+ bounce around the most. He went from being one of the worst hitters to being one of the best hitters to being one of the worst hitters to being one of the best hitters. I don’t know what it meant. It just instantly became the most interesting thing about Ryan Raburn.

Okay! So, since 1900, there have been more than 8,300 cases where a player was a “qualified” hitter in consecutive years. Who had the biggest year-to-year drop in wRC+? You might be able to guess this one — it’s Bryce Harper, who just saw his wRC+ drop by 85 points. Though he wasn’t bad by any means in the most recent year, he wasn’t the destroyer of worlds he’d been the summer before. Rumors continue to swirl that Harper was playing through significant pain.

Bryce Harper’s wRC+ just lost 85 points. A massive, historic drop. If you look at the last two years and reduce the playing-time minimum, the guy with the second-biggest drop, at 81 points, is Ryan Raburn.

The pattern, therefore, continues.

The first time around, I looked at four-year stretches, with a minimum of 200 plate appearances in each. Raburn has batted at least that many times every year since 2009, but since he’s often been close to 200, I opted to lower the minimum to 150 plate appearances. Now to look at five-year stretches. I had a pool of 12,044 five-year stretches to consider. Here are the stretches with the biggest wRC+ standard deviations:

Hitter Volatility, wRC+
Player First Year Last Year Y1 Y2 Y3 Y4 Y5 Standard Deviation
Ryan Raburn 2012 2016 28 149 50 154 73 57.7
Ryan Raburn 2011 2015 94 28 149 50 154 56.8
Ryan Raburn 2010 2014 120 94 28 149 50 49.6
Dusty Rhodes 1953 1957 89 181 125 83 55 48.5
Danny Valencia 2012 2016 26 140 85 136 118 47.2
Ryan Raburn 2009 2013 129 120 94 28 149 46.9
Danny Valencia 2011 2015 83 26 140 85 136 46.7
Travis Hafner 2004 2008 158 166 176 121 64 45.8
Travis Hafner 2005 2009 166 176 121 64 115 44.9
Bernard Gilkey 1996 2000 152 102 74 117 34 44.6

It’s Ryan Raburn! In second place, overlapping Ryan Raburn. In third place, overlapping Ryan Raburn. And then a somewhat distant Dusty Rhodes. But one thing about standard deviations is that they don’t really consider sequencing. Going 100 – 100 – 50 would look the same as going 100 – 50 – 100. The second example looks more volatile, so to capture that, I’ve looked at the total wRC+ change. I took the absolute values of the changes between each year and then added them together. The leaders:

Hitter Volatility, wRC+
Player First Year Last Year Y1 Y2 Y3 Y4 Y5 Total Change
Ryan Raburn 2012 2016 28 149 50 154 73 405
Ryan Raburn 2011 2015 94 28 149 50 154 390
Ryan Raburn 2010 2014 120 94 28 149 50 312
Danny Valencia 2011 2015 83 26 140 85 136 277
Danny Valencia 2010 2014 117 83 26 140 85 260
Clyde Barnhart 1923 1927 151 91 114 31 116 251
Joel Youngblood 1980 1984 102 164 75 138 101 251
Roy Campanella 1952 1956 120 154 75 150 89 249
Rafael Furcal 2007 2011 82 171 93 126 83 243
Lou Piniella 1972 1976 136 76 114 38 106 242

It’s not even close. Over the last five years, Raburn’s wRC+ has changed by an average of about 101 points a season. The nearest non-Raburn name is 2011 – 2015 Danny Valencia, at an average of about 69 points a season. Raburn established a historic pattern, and then continued it. I wasn’t expecting that, even though, you know.

Basic pattern recognition would suggest Raburn is now due for another offensive breakout. He happens to be a free agent, and the last time he was linked on MLB Trade Rumors was last March 29. Every team in baseball would tell you, no, that conclusion is stupid, that’s not how this works. But I think we can all agree that baseball probably doesn’t quite understand how Ryan Raburn works. How could it?
