I very rarely write about the Indians since I almost never get a chance to watch their games out here on the west coast. But last week ESPN’s Buster Olney blogged about whether modern attitudes toward blocking the plate have changed in light of injuries like the one suffered by Santana in Boston. I thought it was an interesting question. (I’ll link to the post here, but unless you have ESPN Insider, it won’t do you any good.)
For those of you who can’t or don’t want to read Olney’s post, the essence of it is that the GMs he spoke to in both leagues mostly agreed that it’s not worth it anymore. At least, not in the case of a guy like Santana, who’s your everyday catcher, arguably a franchise player, and someone whose bat you need every game.
However, I’ve also heard other people argue that this incident speaks to a larger problem—that Santana was behind the dish to begin with. Since the injury, multiple analysts (of admittedly varying caliber) have suggested that when he comes back next year, Santana should be moved to either first base or DH.
This raises a very simple question: how good a defensive catcher is Santana? I’m all for protecting a potential franchise player, but if part of the reason he’s a potential franchise player is that he’s a good or great defender, moving him out of his natural position (and possibly out of the field entirely) seems like a bone-head solution.
Keeping in mind that we’re talking about a total of only 40 games—in his rookie year, as well—I’ve compiled some relevant defensive stats for Santana below. Before looking at that, though, here’s a description of what these statistics mean:
Fielding %: A simple stat calculated by dividing the number of cleanly fielded opportunities by total opportunities for a putout.
Rdrs: Defensive Runs Saved Above Average. An aggregate stat meant to provide an overall defensive rating. In short, how many total runs does the opponent NOT score thanks to your player’s defensive prowess that they would score against an average player at the same position?
Rdrs / yr: Defensive Runs Saved Above Average per 1,200 Innings (~135 games). A version of the previous stat improved by standardizing for the number of innings played. To relate to basketball terms, Rdrs / yr is equivalent in a way to “per 36 minute” stats. In other words, if everyone played the same number of innings, how would they rate? In this stat, a back-up defensive specialist would rate better than a poor-fielding everyday player, even though the everyday player might look better in unadjusted Rdrs simply because he plays so many more innings than the back-up.
Rf/9: Range Factor per 9 Innings. Calculated as 9 * (Putouts + assists) / innings played. A more informed alternative to Fielding % developed by sabermetrics godfather Bill James. The idea here is that by calculating the total number of outs in which a player participates, you get a much better picture of how much ground the defensive player covers per 9 innings.
For instance, say you have a 350 lb catcher. He fields every ball cleanly, but only if the ball stops rolling within 6 inches of the plate. He only makes one play all year. His Fielding % is 1.000. On the other hand, a catcher with superhero agility gets to everything within 50 ft of home plate. He gets to 100 balls in a season, but makes two errors. His Fielding % is .980. Is the 350 lb catcher really a better defender? No, but only Range Factor would tell you that.
CS%: “Caught Stealing” percentage. A simple stat calculated by dividing the number of base-runners thrown out by the total number of steals attempted against a given catcher.
OK, with the mini-glossary out of the way, let’s see how our man Santana was doing in these categories during his 40 games. The number to the right of the vertical bar is the league average for catchers.
CARLOS SANTANA VS. LEAGUE AVERAGE - 2010 DEFENSIVE STATS
Fielding %: .989 | .991
Rdrs : 1 | N/A
Rdrs/yr: 4 | N/A
Rf/9: 7.07 | 7.40
Rf/G: 6.68 | 7.31
CS%: .353 | N/A
Since we don’t have league averages for half the stats we want to examine, let’s look at how Santana rates against last year’s AL Gold Glove catcher. I’ve included the 2009 league average stats where applicable:
JOE MAUER VS. LEAGUE AVERAGE - 2009 DEFENSIVE STATS
Fielding %: .996 | .992
Rdrs : 3
Rdrs/yr: 4
Rf/9: 7.24 | 7.48
Rf/G: 6.93 | 7.39
CS%: .260
What does this tell us? Well, for one thing, that the AL Gold Glove probably went to the wrong catcher last year. Mauer’s Fielding % was above average, but that’s about the only elite level qualification he had defensively—and even there we have to move to the third decimal place to see a difference. A 26% caught stealing rate isn’t scaring too many base-runners either, though I suppose CS% may not factor into Gold Glove consideration.
That said, while both 2009 Mauer and 2010 Santana were below average in Rf/9 and Rf/G for catchers, Santana was further below average in both categories (-.09 further below league average in Rf/9 and -.17 further below league average in Rf/G). However, Santana threw out a much higher percentage (+9%) of would-be base-thieves and was on pace to match Mauer in Rdrs / yr.
But considering the reality of Mauer’s numbers, we should compare Santana to 2009’s league leaders in each category if we want to get a more accurate picture of his skill level:
2010 SANTANA VS. 2009 A.L. LEADERS - DEFENSIVE STATS
Fielding %: .989 | .997 - Gerald Laird (DET)
Rdrs : N/A (Baseball Reference doesn’t break out league leaders for this)
Rdrs/yr: N/A (ditto)
Rf/9: 7.07 | 8.70 - Jason Varitek (BOS)
Rf/G: 6.68 | 8.27 - Jason Varitek (BOS)
CS%: .353 |.537 - Kenji Johjima (SEA)
Based on the above, there’s not a strong statistical argument for keeping Santana behind the plate next year. He was inferior to last year’s AL leaders in every category for which I can find a rating, and noticeably below this season’s league average in half of the them.
That said, we should keep in mind that we’re dealing with a rookie who caught for 25% of a full season. Projecting Santana’s entire career behind the plate based on this sampling is ludicrous. The most important thing is that in order for us all to know for sure, he should quit sticking his leg into the base path to save one run in a meaningless game in August. Especially since the comparison of his defensive numbers to Joe Mauer’s suggests that Santana could be an MVP candidate if his bat comes through (in a major way) for the Tribe. Whether or not it would be deserved is a question to consider in another post. Hopefully we have a good reason to write it in a year or two.
