FanGraphs is proud to be a sponsoring partner of the third Saber Seminar, a great event held each year in Boston. The two-day gathering will be held on August 17th and 18th on the campus of Boston University, and the list of 2013 speakers is pretty amazing. Along with a former Major League pitcher, current executives, scouts, and a wide range of insightful people from various industries associated with the sport, Bill Petti, Dave Allen, and myself will represent FanGraphs at the event, and you will probably find a few other FG personalities hanging around as well.

I attended the event last year, and it was one of the highlights of the year for me. There were some really great research presentations — one of the people presenting this year as a member of the Royals front office presented last year as a grad student, so I think you can guess that his presentation was pretty neat — and a lot of fascinating discussion with many of the brightest people in and around the sport. If you’re going to be in the Boston area that weekend, I highly recommend attending, and it’s probably worth traveling to Boston that weekend to take part even if you’re not a local.

“Stabilization” plate appearance levels of different statistics have been popular around these parts in recent years, thanks to the great work of “Pizza Cutter,” a.k.a. Russell Carleton.  Each stat is given a PA cutoff, each of which is supposed to be a guideline for the minimum number PAs a player needs before you can start to take their results in that stat seriously.  Today I’ll be looking at the issue of stabilization from a few different angles.  At the heart of the issue are mathy concepts like separating out a player’s “true skill level” from variation due to randomness.  I’ll do my best to keep the math as easily digestible as I can.

As I’ve mentioned previously, top prospects tend to be a rare breed at the Triple-A level. Triple-A players tend to be guys about which we have a pretty good idea, and if they’re really good prospects, they probably aren’t long for the level. So when a night features two top prospects on the mound, it’s a good idea to go. This time meant seeing Adam Morgan from the Phillies organization and Daniel Corcino of the Reds organization.

In a Friday matinee, the sensational Matt Harvey will take the mound for the Mets against the Cubs in Chicago. Though the Cubs are hardly to be considered a daunting opponent, Harvey’s right-handed, and the Cubs hitters to be worth a damn so far are the left-handed Anthony Rizzo, the left-handed Luis Valbuena, the left-handed Nate Schierholtz, and the left-handed David DeJesus. At a glance, you might figure this could be a tougher matchup for Harvey than it seems.

And it might well play out that way, because, baseball. The other day, after Dave Cameron ripped the Mariners for starting Raul Ibanez against CC Sabathia, Ibanez singled and homered. Hilarious! There’s absolutely not a single way to know how a given player is going to perform on a given day. Harvey might be aces, Harvey might be awful, or he might be somewhere in between. But if we’re going to think about the probability, we shouldn’t be worried about Harvey facing the Cubs’ lefties. Because to this point in his career, Harvey’s been doing something unusual.

This is a slightly different type of article. I will look at how a single franchise has filled a single spot on the diamond. The Braves have had a pretty good track record with center fielders, developing three of the top fifty center fielders of all time, Wally Berger (#46), Dale Murphy (#37), and Andruw Jones (#9).

But when they didn’t happen to draft or sign a historically good CFer, their approach became much more patchwork. Center field is one of the most important positions on the field, and one of the most difficult to fill. Here’s how the Braves did it.

There are a few different ways I could begin this post, and I can’t settle upon a best one, so you’re going to get them all. Prepare for a blitz of introductions. Jason Grilli was the fourth overall pick in the 1997 draft, and he was sent from the Giants to the Marlins in a trade for Livan Hernandez. He made his big-league debut for Florida in 2000, when he was 23 years old, and as a starter he worked 6.2 innings. In that one debut start, Grilli allowed more baserunners than he’s allowed so far in 2013 as the Pirates’ closer. As of Wednesday, he’s up to 16 saves.

Moving on. Every year, a handful of pitchers try to come back from existing completely off the radar. Most of them try to return and fail, but sometimes they succeed and make for improbable stories. A few years ago there was Ryan Vogelsong, and now there’s Scott Kazmir, who everyone previously assumed was never to be heard from again. Another guy trying to come back is Jeremy Bonderman, with the Mariners organization. He’s presently in Triple-A, and while he might not make it back to the majors, at least he knows a part of him is alive and well at the highest level. Because it was Bonderman who gave Jason Grilli some invaluable advice on developing and harnessing a slider.

Apparently, a memo went out to every major media organization that covers Major League Baseball, telling them that they should write about the ever increasing rise of strikeouts in the sport. Back in March, Tyler Kepner wrote this article for the New York Times. Last Thursday, Scott Miller did a piece on the topic for CBS Sports. On Monday, Joe Lemire tackled it at Sports Illustrated. On Tuesday, Anthony Castrovince weighed in at MLB.com. Pretty much all of them hit on the same general points, with a continuing focus being on the change in approach among hitters. Each writer notes that the rise of statistical analysis has taken some of the stigma away from the strikeout, to the point that a hitter who strikes out 150 or 200 times per year is no longer considered to be an offensive black hole.

There’s almost certainly something to that idea, as we even published an article yesterday explaining why the Braves historic strikeout pace hasn’t really hurt their offensive production. It’s hard to argue that the move towards more analytical approaches to team building haven’t decreased the emphasis on strikeouts as a measure of offensive contribution, and it’s likely that the modern front offices care much less about strikeout totals for their hitters than those of the previous generation.

With J.J. Putz’s elbow hurting, the Diamondbacks have turned to Heath Bell in the closer’s role. Tuesday night against Atlanta, Heath Bell converted his fifth save in six last-inning save opportunities in impressive fashion: after the first baserunner reached on an error, Bell struck out Evan Gattis and Dan Uggla swinging before retiring Chris Johnson on a fly ball to center. Wednesday afternoon, Bell added another, as he worked another hitless and walkless inning, including a strikeout of Justin Upton.

Bell’s debut outing with Arizona looked like the beginning to another ugly season, as he allowed three runs on four hits (including two home runs) and managed just one out. Since then, Bell has been brilliant: over 18 appearances (17.2 innings), Bell hasn’t allowed a home run and has recorded 22 strikeouts against just two walks, good for a 3.06 ERA and a stunning 0.87 FIP. These two saves against Atlanta featured the drivers behind Bell’s success: impeccable fastball control, and the willing to go to it whenever he needs a strike.

The Astros have the worst team strikeout rate in the history of baseball. It’s not even particularly close, as these things go. The Astros have struck out in 26.8% of their plate appearances. The 2010 Diamondbacks struck out in 24.7% of their plate appearances. That’s a gap of more than two percentage points, in a rate that usually fluctuates between 15-25% or so. That’s terrible, and the only consolation is that the Astros were projected to be terrible so no one really cares.

Then right behind the 2010 Diamondbacks are this year’s Braves, at 24.5%. So, this year’s Braves have the third-worst team strikeout rate in the history of baseball. Between third and fourth there’s a gap of another 1.6 percentage points. The Braves, obviously, have the second-worst team strikeout rate this season. Just glancing at their current box score, they’ve struck out six times in four innings against Ian Kennedy on Wednesday. They’re going to strike out more before this game is through. Probably. I guess I can’t be certain.
