From premier prospect to Pittsburgh Pirate: Examining Craig Hansen’s struggles through Pitchf/x

August 12, 2008 – 11:22 am

Craig Hansen looks like a dominant reliever. A hulking 6-6, 240 pound righthander with excellent arm strength and a slider that can make grown men weep on occasion, Hansen was ticketed for near-immediate success following his selection in the first round of the 2005 amateur draft. The Boston Red Sox popped Hansen with the 26th overall pick, dishing out a $4.4M major league contract on the premise that the St. John’s star would be ready to shoulder a high-leverage role in the bullpen in short order.

Suffice it to say, Hansen has not lived up to those expectations in his professional career. Hansen missed a good deal of bats in the minors (8.28 K/9) and posted a superficially impressive 2.62 ERA, but his inability to throw consistent strikes led to inflated walk totals (4.32 BB/9). In 76.1 career major league innings, Hansen has struck out just 6.84 batters per 9 innings, a tepid number for a reliever thought to possess dominant stuff, while dishing out 5.3 walks/9. The Red Sox, not exactly teeming with quality bullpen arms, were nonetheless willing to ship out Hansen as part of a much larger deal that netted Pittsburgh’s Jason Bay.

Now in Pittsburgh, Hansen’s chances to play a significant part in the ‘pen have increased exponentially. With Matt Capps (shoulder) on the rehab trail and Damaso Marte now pitching in the Bronx, the esrtwhile top prospect can work his way into a prominent role, should Hansen’s performance merit a chance at late-inning heroics.

What, exactly, has led to the discord between Hansen’s scouting reports (high-90’s gas, wicked slider) and his performance (1.29 K/BB, 76 ERA+)? To find out, I am going to delve into Hansen’s Pitchf/x data, searching for a reason why the man ticketed to become Boston’s closer is instead pitching mop-up innings for Pittsburgh.

A few general points

August 9, 2008 – 4:42 am

Sorry I haven’t gotten too much–I mean anything–posted so far guys, I’ve been experiencing some technological differences (if you haven’t seen the movie Idiocracy, go rent it you will be a better person) on a couple more fun articles in the pipeline, but I’ll couple things that have been bugging me. As posted by Kyle regarding the complete cheddar Zumaya throws:

Don’t let the 100 mph fastball fool you; Zumaya is high-risk.

The line of thinking Kyle is referring to here which I have seen quite a bit is backwards. Completely aside from Zumaya’s scary arm action or anyone’s mechanics period, simply the fact that he does throw 100+ makes him higher risk. I’m baffled as to how something this intuitive has gotten lost in the shuffle, but I’ll explain it anyway inside the link…

Injury Report: Joba Chamberlain

August 9, 2008 – 12:05 am

Joba hits the 15-Day DL with stiffness in his throwing shoulder...

Joba Chamberlain hits the 15-day DL with “stiffness in his throwing shoulder.” He saw Dr. James Andrews, but fortunately didn’t need surgery and reportedly will not miss major time. Like I said before, his timing at footstrike is worrisome, and his followthrough is abrupt. Problems with his shoulder do not surprise me in the least.

In other news, I am in Cleveland, OH right now for my reception for my family here. Again, sorry for the lack of updates (it’s becoming a theme, one that will stop soon), but I’ve been very busy, as have the other writers. We are completing the move to the SB Nation network soon, and I thought I’d share our new logo with the public:

New logo for Driveline Mechanics!

Let me know what you think!

A look at Chris Carpenter’s return to the big leagues

August 7, 2008 – 11:29 am

When the Brewers traded for CC Sabathia and the Cubs traded for Rich Harden people were waiting for the Cardinals to make a move to answer.  That move never came, but the front office explained that the returns of Mark Mulder and Chris Carpenter would be like their mid season trade and bolster their staff.  After Mulder went down again when Carpenter came back after only a little more than a year after Tommy John surgery people were obviously sceptical but Carpenter has pitched well in his first two starts despite being a little erratic with his control.  The real question is does Carpenter have the stuff that made him a Cy Young pitcher or has the surgery sapped him of some of stuff?  Here is a look at his movement on his pitches.

Injury Report: Joel Zumaya

July 27, 2008 – 6:01 pm

Tigers’ reliever Joel Zumaya left the game with “tightness in his tricep.” Tightness in the upper arm (tricep and bicep muscles) are indicative of torn or damaged elbow ligaments. As I pointed out in a previous post, Zumaya’s arm is still horizontal when his shoulders turn (possibly as a result of his W-arm positioning), thus increasing the load on his Ulnar Collateral Ligament due to unnecessarily violent external rotation about the shoulder.

As always, we’ll monitor the situation at Driveline Mechanics. There’s a lot to like about Zumaya (specifically his straight-forward stride), but there’s a lot of mechanical flaws. Don’t let the 100 mph fastball fool you; Zumaya is high-risk.

Transaction Analysis: Indians convert spare parts into prospects

July 27, 2008 – 3:35 pm

Cleveland Indians

Acquired Minor League C Carlos Santana and Minor League RHP Jonathan Meloan from the Dodgers in exchange for INF Casey Blake and cash considerations; acquired RHP Anthony Reyes from the St. Louis Cardinals in exchange for RHP Luis Perdomo

The Tribe do the July 31st dance as well as any organization in baseball. Be it a grandoise pilfering, such as acquiring Cliff Lee, Grady Sizemore and Brandon Phillips from the Expos for Bartolo Colon, or something less glamorous yet eminently prosperous, such as converting a lukewarm Broussard/Perez DH platoon into Asdrubal Cabrera and Shin-Soo Choo (Thanks, Seattle!), Cleveland’s front office just gets it.  Having effectively waived the white flag following the unloading of C.C. Sabathia, the Indians managed to convert a 34 year-old, league average bat into two interesting prospects, while also flipping a reliever for a a righthanded starter who retains a fair amount of promise.

Injury Report: Phillipe Aumont

July 27, 2008 – 1:39 am

Greetings from beautiful San Diego! I’m in Coronado right now, enjoying the island and the wonderful weather. I’ll head off to a Padres game this week, where they host the Diamondbacks, but otherwise haven’t paid much attention to baseball (much to the excitement of my new wife).

That being said, it has come to my attention that Mariners’ prospect RHP Phillipe Aumont has been on the DL since June 10th with a sore elbow. Looking back, I said that his late arm positioning at footstrike would cause this to be a problem, and it looks to be true so far. Scouts and front office types said that he was going to be shut down for two weeks anyway due to workload concerns, but it’s been well over a month now.

I have a great article I want to post on about followthrough and why the Marshall-trained pitchers look like they have a terrible deceleration phase, but why the reality is much different. More on that next week, hopefully after the SB Nation merger.

Player Profile: Max Scherzer

July 25, 2008 – 8:38 am

Introduction

Scherzer’s Repertoire

Max Scherzer is a three pitch pitcher; four seamed fastball, slider, and change up.  Here is a look at the movement of those three pitches.

Let’s take a look at these pitches one at a time starting with Scherzer’s fastball.  While Scherzer throws a four seamed fastball his 3/4 arm angle gives his fastball more horizontal but less vertical movement than league average.  Scherzer also will drop down even further than that on occasion and unload a fastball that has huge horizontal movement in towards a right handed batter.  You can see how his arm angle directly changes the movement on this pitch as his arm angle lowers.  Most pitchers who throw from a lower arm angle like Scherzer don’t have quite the same giddy up on their fastballs trading some velocity for increased movement.  Velocity though isn’t a problem for Scherzer who is average 94.5 MPH with his fastballs this year.  That combination of extra horizontal movement and plus speed is uncommon and really makes things hard for right handed batters.  Because Scherzer threw both in the rotation and in the pen this year we can check his wear pattern to see how that transition affected his fastball…

Is Tony Pena Jr. the next Rafael Betancourt?

July 22, 2008 – 7:14 am

Upon checking the box scores this morning, I came across the following line during a 19-4 Detroit drubbing of the Royals:

Pena  1.0 IP 0H 0R 0ER 0BB 1K

Expecting to see the usual hilarity that ensues when a position player takes the mound (a la Jamie Burke), I queued up Pena’s inning on MLB.TV.

Wow. Instead of poorly-placed, low-80’s junk, Pena was bringing it. The offensively- challenged shortstop hit the low-90’s on several occasions, and even mixed in a few curveballs. Intrigued by Pena’s performance, I decided to take a look at his Pitch F/X data for the outing.

News: Period of Absence

July 18, 2008 – 2:17 am

Well, everyone, I am writing from my home computer for the last time in this apartment, as nearly everything else (except clothes) are packed for my move cross-town from Lake City to Ballard. My birthday is today (I’m 25), my bachelor party spans this weekend, and then I’m getting married on Thursday. Internet won’t be set up in my house until next Friday, during which time I will be in San Diego for my honeymoon, watching the Padres and Diamondbacks in addition to touring the San Diego Zoo and relaxing on the beach.

So, in other words, don’t expect any substantive updates from me in the near future! Hopefully the new writers will hold down the fort before we transition to the SB Nation network.
