Who is the “most valuable third baseman in baseball”? Wins Above Replacement can be one tool to help answer that sort of question, but using a single season’s WAR number can sometimes leave us subject to random fluctuations in single-season performance that may not fully reflect a player’s real, long-term value. For that reason, I like to use a longer-term test of true WAR-generating results, say for example, over a three-year period. Let’s try a three-year test over the history of the third base position and see what we come up with as a running measure of who has been the “most valuable third baseman in baseball”.
One note on method first. Over the past three seasons (actually more like two and four-fifths seasons), 2010 through 2012, Miguel Cabrera has accumulated more total WAR than any other major leaguer at any position. Cabrera is also playing third base this year. So arguably he is the most valuable third baseman in baseball. But before this year, he hadn’t played any third base since 2008 and had not been a regular at that position since 2007. So it’s a little odd to say he’s been the top third baseman in baseball over the past three years. For purposes of this exercise, I’ve only included as eligible to be the “most valuable third baseman over a three-year period” those players who, over the three-year period being measured, played third base more than they played any other position. That test knocks Cabrera out of the running for the third base title for 2010-2012 (although it does make him the most valuable first baseman over the past three years).
So who is actually the third baseman with the most WAR over the 2010-2012 period? According to baseball-reference’s numbers, Adrian Beltre has opened up a meaningful lead, at 17.4 WAR for 2010-2012, over Evan Longoria at 15.8, as of today. Longoria has struggled since getting back from the injury that cost him a good portion of the season, but he is still within range of catching Beltre if he gets hot and Beltre tails off — either one could still end up as the third baseman with the most WAR over the full 2010-2012 period.
Longoria is looking to hold on to the “top three-year-WAR” title among third basemen that he held after both 2010 and 2011. Here’s a list of all the “top three-year-WAR” title holders among major league third basemen, going back to the beginning of the 20th century. As you read the list, keep in mind that when it says that Longoria held the title for 2010 through 2011, that means he had the most WAR (baseball-reference version) in the majors among third basemen for the three-year period 2008 through 2010 and then also for the three-year period 2009 through 2011.

A couple of points regarding this list:
— The number of WAR required to be the third base leader over a three-year period varies enormously from one three-year period to another. So for example, over the three-year period ending with 1967, Ron Santo totaled 25.6 WAR, the most over a three-year period by any major leaguer whose primary position was third base. Contrast that with, for example, the total of 7.4 WAR accumulated by Pinky Higgins over the three years ending in 1934. Although that 7.4 WAR three-year total would have been merely the fourth-best one year WAR in Santo’s career, it was nevertheless the best three-year total by a third baseman in the majors over that 1932-1934 period.
–Because there is such a wide variation in the number of WAR needed to get on this list, some guys with high WAR numbers will fall short if they those high numbers come in the wrong three-year period. After the 1979 season, George Brett had a three-year WAR total of 20.9, which was the second-highest three-year total by any hitter at any position over those three years, 1977-1979. That level of three-year WAR would usually be plenty good enough to be the top third baseman in the majors over a three-year period. But Brett doesn’t appear on this list for 1979, because Mike Schmidt’s WAR total over 1977-1979 was even higher than Brett’s. That happened to Brett quite a bit — one of the greatest third basmen ever to play the game, but not the greatest third baseman of his generation.
–You may notice that in a few instances, two guys are designated on the list for the same year. That’s because there was a tie for the lead for that particular three-year period — in those cases, I’ve listed both guys.
