When you think of 2019 baseball, there’s probably a definite picture in your mind. Contact is rare but dangerous. Home runs fly out of the park at record levels on fly balls, and line drives are smashed left and right. Strikeouts are abundant, baserunners scarce. And when those runners do get on, they don’t steal very frequently, leading to a station-to-station game.
That’s a great aggregate — but who do you picture when you picture 2019 baseball? Maybe you see Mike Trout or Christian Yelich in your mind’s eye, but that’s not really right. They might be the best of 2019, but they’re certainly not the embodiment of 2019. Yelich and Trout don’t have strikeout problems that sap their on-base percentage. They hit for average and for power; heck, Yelich ended his season batting .329, and it’s not out of the question that he’ll win the batting title. That’s about as far from typical 2019 as it gets.
Not only that, but they’re both fast boys, even if Trout doesn’t steal as much as he used to. Yelich was on pace for a 50/30 season before his season-ending injury, and the fact that it would be the first such season in history should tell you that he’s not anything approaching average. Trout and Yelich are the face of baseball in 2019, but they’re not a fair representation of it.
If it’s not the game’s stars, could it be some kind of boom-or-bust slugger, a watered-down version of Nelson Cruz who sends balls out of the park often enough to offset a cover-your-eyes strikeout rate? Oakland’s Khris Davis, the .247 batting average king, is having too down of an offensive year to qualify, but what about Justin Smoak, another true-outcome-centric batter who would just as soon take a walk as swing at a pitch? He’s not really representative either! He walks 16.3% of the time, double the league average — that’s clearly no good.
To answer this specifically and arbitrarily posed question, I settled on some rules. I chose average, on-base percentage, slugging percentage, walk rate, strikeout rate, home run rate, and stolen bases per plate appearance as the statistics that I’ll use to define average. You could make an argument that including all triple-slash stats is focusing too much on batting lines, or that some batted ball data should be folded in, but for me, those don’t stand up.
