Why yes: performance. If you want to argue that Carlos Correa is already baseball’s best shortstop, you can simply point to his performance, and to the performances of the other shortstops. What could be easier? Correa, of course, hasn’t played a full 2015 season, but he has batted a couple hundred times, so let’s look at the numbers and keep them all above a common, 600-plate-appearance denominator. Do that and Correa comes out as a top-10 position player. The closest shortstop, by WAR, is Brandon Crawford, who trails by just about two wins. Whatever you think of the error bars in WAR, two wins per 600 plate appearances is a big margin. The argument, in other words, has decent support.
Why no: projections. Statistics reflect talent, but they can also mislead. It can be better to refer to the projections, as they can be a decent proxy for current estimated true talent. Projections don’t suffer from recency bias. They don’t suffer from hype, and they don’t suffer from any sort of overreactions. Looking at the shortstop depth-chart projections, and putting WAR over 600 plate appearances, Correa is basically tied with Crawford and Jhonny Peralta, a win behind Troy Tulowitzki. Some months ago, Tulowitzki was the unquestioned best shortstop in baseball. How much should we really reconsider, after part of one season?
If you choose to believe Tulowitzki remains the best shortstop, that’s fine. It’s totally justifiable, and Correa still doesn’t have an extended track record. Could have a slump just ahead of him. Could be a bad one. But as absurd as it might sound, Correa really does have an argument of his own. He’s been that good to date, and if you don’t believe he’s better than Tulowitzki yet, it seems only a matter of time until the trend lines intersect. One of them turns 31 in two months. One of them can finally buy his own drink in a month and a half.
