A Loathsome Semantic Point Regarding Spring Stats
It has been noted by people smarter than the present author — and also by Jeff Sullivan — that it’s best to approach spring numbers with a great deal of caution so far as drawing conclusions is concerned regarding what they might suggest about a player’s true-talent level. While research from last March by Mike Podhorzer and Matt Swartz reveals that, in certain cases, spring numbers actually do possess some predictive value, this is likely an instance of exceptions proving rules.

Still, to say that spring numbers are “meaningless” because they lack predictive value for the upcoming season is likely not quite right, either. As Dave Cameron recently noted in a February piece on the relevance of WAR, every stat “is simply the answer to a question.” A question that the present author has some interest in answering is “Which players are performing the best this spring?” — not necessarily with a view to how it might inform their regular-season production (although I’m willing to become irrationally exuberant with little provocation), but merely in and of itself. Any numbers that answer that question have “meaning” to that end.

Of course, some metrics are still unpalatable in small samples. Clayton Kershaw‘s 9.00 ERA in 8.0 spring innings probably tells us less about his performance so far than the 12:1 strikeout-to-walk ratio he’s posted against 42 batters (for a strikeout and walk rate of 28.6% and 2.4%, respectively). Likewise, knowing what we do about certain metrics and the rates at which they become reliable, it’s also manifestly the case that Royals third baseman Mike Moustakas will not continue to bat .545 (on the strength of a BABIP nearing .600). Walks and strikeouts, though — and home runs for batters — are all readily available, become stable rather quickly, and account a great deal for a player’s ability either to produce or prevent runs.

All of which concludes the author’s lengthy and unnecessary justification for publishing below the SCOUT leaderboards for spring.

SCOUT Leaderboards: Spring Training
SCOUT Leaderboard: Spring Hitters
Below is the current SCOUT batting leaderboard for spring training. SCOUT+ is calculated using regressed home-run, walk, and strikeout rates, where 100 is league average (in this case, for all spring hitters) and above 100 is above average. xHR%, xBB%, and xK% stand for expected home run, walk, and strikeout rate, respectively.


Player Team Pos PA xHR% xBB% xK% SCOUT+
Ryan Raburn CLE 2B 20 3.8% 9.0% 16.9% 116
Nolan Arenado COL 3B 17 3.9% 8.2% 16.6% 115
Domonic Brown PHI RF 29 3.4% 10.6% 17.8% 114
Jason Bay SEA LF 12 3.2% 10.4% 17.2% 113
Miguel Cabrera DET 3B 22 3.5% 8.4% 16.0% 112
Allen Craig STL 1B 15 2.9% 10.8% 16.2% 111
Shane Robinson STL CF 21 3.2% 9.5% 16.1% 111
Steve Pearce BAL 1B 12 3.6% 8.9% 17.9% 111
Craig Gentry TEX CF 18 2.9% 10.1% 15.8% 110
Prince Fielder DET 1B 21 3.2% 10.0% 17.4% 110

SCOUT Leaderboard: Spring Pitchers
Below is the current SCOUT pitching leaderboard for spring training. SCOUT- is calculated using regressed strikeout and walk rates where 100 is average and below 100 is above average. xK% and xBB% stand for expected strikeout and walk rate, respectively.


Player Team IP TBF xK% xBB% SCOUT-
Michael Wacha STL 7.2 28 21.4% 8.4% 90
Brandon McCarthy ARI 5.0 19 21.1% 8.3% 90
Vidal Nuno NYY 5.0 19 21.1% 8.7% 91
Donnie Joseph KC 3.0 10 20.8% 8.5% 91
Clayton Kershaw LAD 8.0 42 20.5% 8.1% 91
Rick Porcello DET 8.0 31 20.4% 8.1% 91
Matt Magill LAD 4.0 16 20.8% 8.5% 91
Ryan Mattheus WSH 4.0 13 20.5% 8.4% 92
Simon Castro CWS 5.0 18 20.6% 8.5% 92
Michael Olmsted MIL 4.0 17 20.7% 8.9% 93

    It is a shame there is no PitchF/X data for spring games as that data might actually enable us to see a change of approach at the plate for hitters and could actually prove useful in predicting performance in the upcoming season.

      I don’t think I buy that, I remember back in 2000, the newly remade Mariners showed up in spring training and Edgar Martinez and John Olerud both started spring by taking absurd numbers of pitches to “re-learn” the strike zone. I used to try to do something similar though I never really played in games that you could safely say didn’t count in order to be safe in doing it. Some batters do drastically different things when they’re attempting to get comfortable than they normally do. If you know you’ve got a job locked up for the season, why not essentially watch pitches for a game or two, get used to seeing the ball without worrying about chasing anything, instead of chasing that curveball in the dirt, learn what it looked like, prevent yourself from developing bad habits early when it doesn’t matter. Rookies and minor leaguers (and some old guys) obviously don’t have that luxury, they’re trying to impress the big league squad and make the team, but if your job is locked up I could see taking an abnormal approach at the plate in an effort to get comfortable before the season starts.

    It’s interesting to see Porcello on that leaderboard given that his lack of strikeouts is why I’ve always avoided him. One thing I wonder about is how the WBC affects these results, as pitchers not involved with it will presumably be facing even weaker lineups than normal.

      I find that interesting too. Having not seen any of the Tiger’s Spring Training games, can anyone who has comment on whether or not he’s actively trying to strike people out?

      Maybe it’s a change in approach from an organizational level to strike out more guys & put less pressure on his infield to field ground balls. .344 BABIP is pretty unlucky…

      Avoiding him because of strikeout rates isn’t a very neighborly thing to do — you could at least say hi once in a while, or stop pretending not to be home when he comes by to borrow a cup of sugar…

    Analyze spring traing?? I can’t even bear to watch it, the difference between the haves and have nots (a job) is remarkable.

  5. MLB Rainmaker says:

    My theory is that Spring stats only matter for guys without a job — its not a matter of the stats, its a matter if the guy is motivated to care about his stats.

    For example, Clayton Kershaw just won the Cy Young, he doesn’t care about his Spring stats, neither does Don Mattingly or Ned Colleti, etc….no matter what he’s the Doyers opening day starter. He’s just trying to get stretched out and work on a few things.

    Michael Wacha on the other hand cares very much about his Spring numbers; he’s got a month-long audition for Matheny and Mozeliak to show he can pitch to MLB quality hitters, in hopes of a shot at the 5th spot in the STL rotation or at least first shot at mid-season call-up.

    From that perspective, I’m excited by what I’ve seen from Wacha, Teheran, Gyorko, Arenado and Gerrit Cole, and on the flip side disappointed by Randall Delgado, Kolten Wong, and Bruce Rondon. For guys like these, a big spring forces their way on the big club and shows they have it in them to compete, a bad spring means a trip back to the minors. I’d be willing to wager any three from the good list have more WAR value than the three on the bad list by the end of the season.

    • rusty says:

      While I think your explanation could be valid in many cases, I don’t agree that the conclusion follows. The amount of instructional time (with the MLB coaching staff) is an important part of spring training, so a prospect that has difficulty spotting curveballs, or hitting to all fields, or cleaning up delivery from the stretch, etc may be asked to work on and display that particular skill. In that case, ability to make adjustments / be coached would seem to be what the bosses are looking for, rather than a straight stat line.

      I couldn’t decide whether to +1 this comment or -1 the very idea. It’s funny how you have to infer from the list above that Seattle has a second Jason Bay, one who can hit, in their system.

    Its not unlucky if youve got an extreme ground ball pitcher in front of a very weak infield defense.

  8. Pft says:

    Stats are simply a measure of what has been done. As with any small sample, they do not usually represent a players true talent level. Does not mean we should not compile them.

    I am more inclined to notice awful numbers as these can sometimes be suggestive the player is not healthy, but not always.

    I suspect teams rely more on what they see than the numbers.

    My lesson was learned when Chris Carter hit 10 Hr one ST and then struggled in AAA.
