Sean Smith has gone a step ahead of all the defensive projections we’ve seen out there by including minor leaguers. He’s been providing minorleaguesplits.com with total zone numbers. Here’s an article on how these numbers are translated. I’m sure they are projected similarly to how others are done, with weighting several years of data.

Here’s the numbers for the Cardinals’ minor leaguers.

Name POS Runs
DeJesus, Antonio OF 11
Jay, Jonathan OF 10
Robinson, Shane OF 9
Jones, Daryl OF 4
Henley, Tyler OF 2
Rapoport, James CF 1
Luna, Aaron OF 1
Freese, David 3B 0
Craig, Allen OF 0
Mather, Joe OF -1
Gotay, Ruben 3B -2
Shorey, Mark OF -2
Hamilton, Mark 1B -3
Buckman, Brandon 1B -3
Arburr, Matthew 1B -3
Stavinoha, Nick OF -3
Solano, Donovan 3B -4
Kozma, Peter SS -4
Brown, Andrew 1B -5
Descalso, Daniel 2B -5
Greene, Tyler SS -5
Folli, Mike 3B -6
Pagnozzi, Matt C -6
Cruz, Tony C -7
Derba, Nick C -7
Sedbrook, Colt 2B -10
Rowlett, Casey 2B -10
Hoffpauir, Jarrett 2B -11
Anderson, Bryan C -12
Hill, Steven C -14

Rally also has his own method for evaluating catcher defense, which is just gravy. The usual caveats apply when looking at these numbers, remember – when in doubt, ask a scout.

Bryan Anderson projects to be terrible. We knew he was bad, but now we have at least one projection on how bad he’d actually be. Zounds. Pagnozzi’s defensive reputation: overrated.

On the positive, Jon Jay, Shane Robinson and David DeJesus come out looking quite good. All of them could hold their own at center field if need be. Jon Jay’s best tool is his bat, or so we’ve long been told, but he has some excellent range. I really like his chances to catch on with the big club this year.  Unfortunately Robinson and DeJesus don’t have the offensive capability to be a lot better than replacement level at this point, unlike Jay, who should be a solid 4th OF.

Bad news for Tyler Henley. His bat profiles much, much better in center, but he projects a bit to be just a little better than average defensively at the corner spots.

Allen Craig and David Freese both project at 0. This is good news for Craig. On the other hand, Freese has put together some solid #’s in total zone, but apparently the translations for infielders are a bit tough. I’ve seen scouting reports that say he’s good, and I’ve also heard he’s average at worst, so this very well could be an accurate projection.

It’s easy to see why the club let Jarrett Hoffpauir go.

Colt Sedbrook won BA’s equivalent of a Gold Glove at 2B. Looks like minor league managers and coaches are as good at handing out these awards as their major league counterparts.

    Craig is a better defensive OFer than Mather? Jay better than S. Robinson? Makes one question this defensive metric.

  2. CRay says:

    Also, no infielders show up above zero – only outfielders – and all catchers and 2Bs are at the bottom of the list. Could be a quirk of our system but does make one take this system with a large grain of salt.

  3. easy says:

    As I remember Jay projected even better last year. I’m hoping he’s one of those rare guys (remember Ken Oberkfell?) who hit better in the majors than minnors.
    I know I’m a Freese apologist but this projection is a small sample and he was coming back from injury and a long layoff.
    Question, does total zone take double plays into account for middle infielders?

    You’re looking at a handful of prospects to question an entire system. Anecdotal opinions shouldn’t outweigh a respectable projection algorithm. This is such a small snapshot of the Cardinals players and of Rally’s overall projection that it’s silly to quibble over individual rankings.

  5. jjray says:

    arzu, don’t get your panties in a bunch. Passing comment about odd results coming out of this metric.

    • azruavatar says:

      Troy Tulowitzki had a higher wOBA than Lance Berkman last year. Does that make the metric wrong? That’s an exceptionally self-indulgent way to question a metric.

      This isn’t a scenario where some single counter-example disproves inductive logic. It’s a probabilistic projection of defense meant to be used as a tool in combination with scouting.
