Projecting the 2013 Nationals, Part 2: Pitching and Defense

In Part 1, we announced the starting line-up. Let’s see how many runs the pitching allows in 2013. My model conservatively estimates that in 2013, Nats pitching will account for 609 runs scored against the Nats, but defense will “save” 18 runs. Thus, the model conservatively predicts that 591 runs will be scored against the 2013 Nationals.

Here’s the table for pitching:

Pitcher Name Projected IP 4-Yr Moving Avg xFIP Projected Runs Allowed TOTAL RUNS ALLOWED
Stephen Strasburg 180 2.56 51.20
Gio Gonzalez 190 3.81 80.43
Jordan Zimmermann 190 3.71 78.32
Ross Detwiler 180 4.44 88.80
Dan Haren 190 3.37 71.14
Rafael Soriano 70 3.6 28.00
Drew Storen 70 3.46 26.91
Tyler Clippard 70 3.54 27.53
Ryan Mattheus 70 4.48 34.84
Craig Stammen 110 3.96 48.40
Zach Duke 90 4.34 43.40
Bill Bray 65 4.19 30.26 609.25

You will notice that my initial guesses for innings pitched for starting pitchers are quite low. We’ll tweak those later, but for now, I’m going to assume that these are good enough to go by.

A similar table of the defensive statistics would be tedious to recount, so let me sum it up with a few general notes:

  • According to these projections, the three biggest defensive assets on the 2013 Nationals are Ryan Zimmerman, Denard Span, and Danny Espinosa.
  • Ryan Zimmerman should save 7.6 runs–best on the team. The high number of defensive runs saved here underscores just how important it is for the Nats to keep him healthy.
  • Danny Espinosa has been the target of a lot of fan frustration lately, especially given his struggles at the plate. His defense, however, is outstanding. The model projects that he will save 5.2 runs.
  • The newest addition to the Nats defense, center fielder (and noted icthyophobe)┬áDenard Span, is projected to save 4.6 runs. Bryce Harper had a UZR of 9.7 as a center fielder last year, so just looking at that, you might think that Span is a lousy center fielder compared to Harper. You’d be wrong. UZR is notoriously unstable–we need at least 3 years of data to get a good sample. Span actually posted a UZR of 9.0 as a center fielder for the Twins in 2011; likewise, as Twins CF in 2012, he posted a UZR of 8.5. As you can see, the projection for Span seems very conservative–but it takes into account some bad defensive years for Span (2008 and 2009). I would expect Span actually to outperform this projection.

Right, that wraps up the top of the inning. Tune in to Part 3, where we’ll discuss how the offense looks.
