On Thursday the Minnesota Twins and catcher Drew Butera avoided arbitration and agreed to a one-year, $700,000 contract, an almost assured sign that Butera will be on the roster as the team's third backstop.
Why, you ask, might the Twins invest almost a million dollars in a player who is completely expendable as the epitome of a replacement level player?
Consider this: Over the past three years Butera's OPS (.497 OPS) has been the worst in the American League and the second worst in all of baseball. Only the Giants' Emmanuel Burriss has had an OPS lower than Butera. This, for all intents and purposes, should be the definition of replaceable.
Almost all of the rational for his retention revolves around his defensive prowess. In fact, Googling "Drew Butera" and "Defensive Prowess" pings back numerous articles using that phrase to describe him. Much like focusing on someone's "good personality" to conceal other glaring flaws (i.e. nasty body odor, operates a baseball blog, etc), "defensive prowess" feels like a similar smokescreen to avoid stating the obvious about his bat.
But how "prow" is his defense?
This question is harder to answer as there is no definite measurement or widely available statistic that accurately portrays a catcher's value based on things like game-calling, framing and/or controlling the run game. One can look at a stat like caught stealing but that tells as much of a story of a catcher's skill has fielding percentage does a shortstop or outfield assists speak towards a right fielder.
In 2011, pitch f/x guru Mike Fast – now an analyst for the Houston Astros – showed the baseball world just how much value could be placed on a catcher's framing ability. By his methods, having a catcher who can coax out a borderline strike could save 15-20 runs per season – the equivalent of one or two wins. Conversely, a bad catcher could cost their team the same amount of runs. Of course, while this data is fascinating, it is something that has not been automated by any sites to make this information publicly available so we do not know if Butera's technique save or cost the Twins runs.
One thing we do know is that Butera has a strong track record of throwing runners out. In 2011, possibly because of Carl Pavano's disregard for the run game, the Twins paired him with Butera who has show a propensity to cutting down base-runners in his minor league career. According to his Baseball-Reference.com stats, between 2005 and 2011, he nabbed 42% of all would-be thieves. This past year, his caught stealing rate plummeted and he managed to throw out just four on the bases.
In George Will's Men At Work -- an examination of some of the game's finer points through the eyes of the best players at the time -- teams will track a catcher's catch-and-release time which is dubbed "pop-to-pop" time. Pop-to-pop time is a measurement used by coaches to separate good catcher arms from bad ones. This means they are stopwatching from the moment the ball hits the catcher's glove until it smacks the middle infielder's mitt. In the book, an unnamed coach rattles off pop-to-pop times.
1.94 seconds: Good.
2.12: That base is good as gone.
2.04: M'eh.
1.85: Nailed 'em.
Overall, the difference between being ninety feet closer to scoring a run or gaining an out is approximately one-hundredth of a second. Naturally, the ability to throw runners out is tied to the pitcher keeping the runner from breaking early.
This brings me to the Twins' trio of backstops. While theft is a shared liability with the battery mate, having a pitching staff that has total disregard for the running game reduces the effectiveness of a defensive catcher. The 2012 Twins were labeled as one of the worst at base-runner attentiveness. That said, Butera's ability to catch and release provided this staff with the best odds of thwarting larceny.

In an inexact study, a stopwatch has shown that over the course of five throws to second, Butera's "pop-to-pop" time averages out to be the best:

So Butera has a better arm or better footwork or a quicker release than the other two, at least in this small sample. Observationally, Butera was able to make these quick throws while handling sliders down and away on at least two of those five examples. This should not go ignored.
Over the entire season, Baseball Info Solution has assigned a value on a catcher's ability to subdue the run game. Of the Twins' three, Butera (0) outperforms both Mauer (-3) and Doumit (-1). So, strictly speaking controlling the run game, Butera's effect on the overall team's performances is slightly better than Mauer and Doumit's but minimal according to BIS. This begs the question, is being able to control the run game worth paying nearly a million for a third catcher?
Someday we may have the tools to be better equipped to answer that question. For now, the Twins are committed to bringing him back – for better or worse.
