Our eyes told us that the 2017 St. Louis Cardinals were not a particularly strong team defensively. Now we have a consolidated metrics-based view of player performance in the field – a measure that is important, as it is 25 percent of the annual Gold Glove Award scoring – the SABR Defensive Index, or SDI.
Yadier Molina’s eight-year reign as the top defensive catcher in the National League ended a year ago when Buster Posey unseated the Cardinals legend as the Senior Circuit’s Gold Glove Award recipient. A new winner at the position was crowned this week in Cincinnati’s Tucker Barnhart.
As Molina continued to demonstrate impressive durability in 2017, leading NL catchers in games played and innings caught, some Cardinals fans feel the 35-year old should have reclaimed the defensive award.
The measurements suggest otherwise, however. According to the SDI, Molina ranked fifth at his position in the NL this season, just ahead of Posey. The top-ranked NL backstop in SDI, San Diego’s Austin Hedges, was not among the top three overall scorers, pre-announced as “finalists,” with Gold Glove winner Barnhart second in SDI.
No measure is the be-all, end all, which is why actual voting by managers and coaches still make up the lion’s share of the Gold Glove scoring, 75 percent. But the SDI has a solid foundation, based on not one, but a group of defensive metrics. Though some discount any single-season’s worth of fielding results, those behind the SDI originally created and refined many of the measurements and devised the Index as a blended measure of multiple stats. (SDI background can be viewed here.)
Overall, the SDIs did not seem to swing the final results hard, with only four of the nine Gold Glove winners having the top SDI at their respective positions.
With that background in mind, let’s look at how several St. Louis Cardinals fared in the final update of the SDI for the 2017 season. (Because of its importance in the Gold Glove Award results, the full-year SDI is not published until after the winners were announced.)
Here are the Cardinals’ individual scores with the league leaders by position listed alongside.
|NL pitchers||Gold Glove||SDI ranking||SDI||Top SDIs||Rk||SDI||Winner|
|Mike Leake||non-finalist||9th of 36||2.8||R.A. Dickey||1||5.1|
|Michael Wacha||non-finalist||21st of 36||0.2||Zach Greinke||8||2.9||GG|

|NL catchers||Gold Glove||SDI ranking||SDI||Top SDIs||Rk||SDI||Winner|
|Yadier Molina||finalist||5th of 14||7.1||Austin Hedges||1||10.7|
|NL first basemen||Gold Glove||SDI ranking||SDI||Top SDIs||Rk||SDI||Winner|

|Tommy Pham||non-finalist||2nd of 11||4.2||Marcell Ozuna||1||6.5||GG|

|NL center fielders||Gold Glove||SDI ranking||SDI||Top SDIs||Rk||SDI||Winner|
|Dexter Fowler||non-finalist||11th of 13||-7.8||Michael Taylor||1||7.9|
|NL right fielders||Gold Glove||SDI ranking||SDI||Top SDIs||Rk||SDI||Winner|
|Stephen Piscotty||NR||Jason Heyward||1||12.8||GG|
These rankings are especially enlightening, since the Gold Glove Award announcements only include the top three vote-getters, the so-called “finalists”.
As it turned out, Molina was neither the top scoring, nor top-ranked Cardinal on defense. Those honors go to Jedd Gyorko and Tommy Pham, respectively.
Gyorko continues to score well in the annual SDI metrics, coming in a very strong third among NL defenders at the hot corner, with the highest Cardinal SDI of 8.9. In left field, Pham finished second overall to Miami’s Marcell Ozuna, the highest individual placement by a Cardinal in 2017.
As a team, St. Louis was shut out of the nine NL Gold Glove Awards for the second consecutive year. Molina was the only “finalist,” indicating Gyorko and Pham did not receive balloting support to the level their SDIs placed them.
At the other end of the spectrum was Carlos Martinez, with the lowest SDI of the 36 NL pitchers ranked. The team’s ace also had a negative SDI in 2016. Newcomer Dexter Fowler came in with the lowest negative score among Cardinals at -7.8. Last year, shortstop Aledmys Diaz had that dubious distinction.
Only three of the 12 Cardinals players listed compiled a negative SDI, however, with Kolten Wong joining the aforementioned two. Still, Wong was still in the middle of the pack of NL second baseman, eighth of 16.
Of the four St. Louis pitchers among the 36 ranked in the NL, now ex-Cardinal Mike Leake was the only one to register in the top half. Michael Wacha and Lance Lynn were in the middle of the pack.
Other St. Louis defenders with positive SDIs for the 2017 season are Paul DeJong, Randal Grichuk and Matt Carpenter. Adam Wainwright and Stephen Piscotty are among the Cardinals not receiving a 2017 SDI score.
