Raising Aces: Walker on the Wild Side

1

Doug Thorburn

Issues with pitch usage and command have led to a rough start for Taijuan Walker.

Anticipation was high for Taijuan Walker's first start of the 2015 season, following an injury-riddled 2014 campaign and an absolutely dominant spring. His line from spring training included just two earned runs allowed across a ridiculous 27 innings of work (seven games). He struck out 26 batters and walked only five, with just 10 hits allowed and a pair of solo homers accounting for the only runs. His raw stuff includes velocity in the mid-90s, a cutter and a hard changeup that both register in the high 80s to low 90s, and the occasional curveball that drops down to the mid-70s on the velo scale. His mechanics have received solid ratings from yours truly in the past, including an overall grade of B- in the 2015 SP Guide, which combined with the hard stuff to raise the optimism surrounding his first start.

Raising Aces: Mechanical Notes from Opening Week

7

Doug Thorburn

A look at how some intriguing arms were throwing this week and some mechanical issues or trends to keep an eye out the rest of the way.

Baseball is finally here, and I couldn't be happier. A winter of hibernation can now give way to a summer of over-analysis, and the Opening Week of the 2015 baseball season has laid the groundwork with a great deal of intrigue on the mound. Let's take a look at some of the pitching highlights of the season's first turn through the rotation.

Raising Aces: Pitching Trident: Downers

0

Doug Thorburn

The author goes through a list of arms he's lower on than most and explains why.

In last week's episode of Raising Aces, we singled out the pitchers that I had ranked higher than the consensus, on the basis of my three-year fantasy rankings here at Baseball Prospectus compared to the Average Draft Position (ADP) at the time that those rankings were formed (late February). This week, we flip the coin to study the downside (there's two sides to every Schwartz), evaluating the hurlers that I had ranked far below their ADPs to see whether there is any rhyme, reason, or merit to my theoretical pessimism.

Raising Aces: Pitching Trident: Uppers

8

Doug Thorburn

The author takes a look at pitchers he has ranked higher than their average draft position.

I like to take a three-pronged approach to pitcher evaluation, following the process-outcome train through stations of mechanics, stuff, and stats. The numbers steal the focus during fantasy draft season, but my personal rankings are heavily influenced by the other two prongs of the trident. Mechanics will sway me (big surprise), but a pitcher's delivery typically needs to be paired with great stuff to cause a real boost in the ranks, and sometimes a pitcher is one small piece away from making that next leap in performance.

Raising Aces: Auditing the Mechanics Report Card

2

Doug Thorburn

Our resident pitching mechanics' expert takes a look at whether he has any tendencies when handing out grades.

An underlying tenet of sabermetrics—hell, of all science—is to continually ask questions, to follow-up on previous research, and to continue to update the analytic paradigm. Accountability is paramount, and though showing proof of one's work can present a humbling burden that forces the confrontation of potential holes in the system, here at Raising Aces we make it a point to have a transparent process that ups the communicative value of pitching evaluation.

Raising Aces: Over the Radar 3.0

4

Doug Thorburn

A look at the arms who have had a velocity jump over the last couple years.

We looked at the players who have been skiing down the slopes of velocity last week, and this time we turn 180 degrees to the pitchers who are fighting the gravity of age with increased velocity.

Raising Aces: Under the Gun 3.0

11

Doug Thorburn

A look at the pitchers who have seen a downtick in velocity over the last few years.

It's that time of year again, where we look back at the pitcher velocity trends of yesteryear to see if we can glean anything about the upcoming season. I'm a bad-news-first kinda guy, so we'll kick off the series by looking at those pitchers who are on the downslope of velocity over the last few years before heading over to the sunnier side of the hill. I also admit to having a side agenda in the form of a theory regarding velocity decline and pitchers who engage extra spine-tilt, an element that has been considered in each of the previous renditions of Under the Gun and which will make another appearance before we are done here today.

Raising Aces: The Eyes of March

14

Doug Thorburn

Which pitchers to watch and what to look for this spring.

Much digital ink has been spilled over the beauty behind the four words that ignite the spring for a Baseballholic: pitchers and catchers report. But it's a tease, because after pitchers and catchers report to spring training we are left with two weeks worth of recycled stories about players who are or aren't in the best shape of their lives. The spring doesn't begin in earnest until ballgames are being played in March, with the first slate on tap to begin next week.

Raising Aces: Trailblazers of Funk

10

Doug Thorburn

After breaking down some of the funkier deliveries in baseball history, we now take a look back at those who were the original bringers of funk.

In the previous edition of Raising Aces, we attempted to establish a grading system for pitcher funk, and this week we look at how some of that funk has translated across time and cultures. A key ingredient to funk is novelty, but what might seem novel to the modern observer might actually have been commonplace 60 years ago, and the techniques that are common in specific areas across the globe might be considered uncommon here in the States. So let's dive into some of the specific forms of funk that have appeared multiple times in the major leagues, and see if we can attach a grade that teases out some of the contextual factors.
