Keen readers of this blog–both of you–will have noticed one glaring omission among all of my calculations. I have thus far decided not to include a certain 19-year-old catcher-turned-outfielder who last saw limited playing time at AA Harrisburg.
In a recent column, the Washington Post’s Jason Reid suggested that Bryce Harper needs to grow up. Given that this is the same Jason Reid whose journalistic insight into the Redskins’ quarterback situation early in the 2011 season gave Washington sports fans–and journalism as a whole– the biggest “Doh!” moment since the night Dewey beat Truman, I was moved to tweet:
Well, if Harper does make the Opening Day roster, how good does he have to be to do no harm to a squad already projected for 86 wins?
Let’s assume Harper is an everyday player. There’s no indication so far that he can play center field. The Nats don’t have anyone available with a positive UZR as a center fielder except Werth. So let’s put Harper in right field. Here’s the most dangerous assumption of them all: assume Harper is a totally average defender.
Assuming a Healthy LaRoche
Let’s also assume that Adam LaRoche is healthy and ready to be his usual self at first base. That rounds out the outfield as Morse, Werth, and Harper.
Someone needs to get bumped off the bench. Given that the Nats went out and got DeRosa and Ankiel, that leaves Roger “The Shark” Bernadina the odd man out, so we need to assume that The Shark doesn’t break camp with the Nats.
Assuming everybody’s an every-day type player, we’ll need to cut down DeRosa’s plate appearances, to reflect his status as a real bench player and not half of a platoon. Let’s give him 250 plate appearances. Same with Ankiel.
As constructed and run through my model, this Harper-less squad is good for 83 wins. Were he to join the Nats as the opening-day right fielder, Harper would need to have a wRC of 25–that is “create” 25 runs over 162 games.
What does 25 wRC look like? It looks like an outfielder not much worse than Aaron Rowand of the Giants, who posted 27 wRC in 2011. Rowand batted .233/.274/.347 with 30 extra-base hits (including 4 home runs) in 2011. That’s a pretty low bar to clear.
But What If LaRoche Isn’t on the Team?
The situation becomes more complicated if LaRoche is not healthy. Morse has to move to first base. Werth slides to center, Harper moves into right. Left field sees a Bernadina/DeRosa platoon. Cameron and Ankiel come along for the ride as bench players. What does this look like now? Not too good, I’m afraid: 73 wins.
To do no harm to the team in this situation, Harper would need to be worth 90 wRC. What does a 90 wRC outfielder look like? Consider Matt Holliday of the Cardinals, who posted exactly 90 wRC in 2011. In 2011, Holliday batted .296/.388/.525 with 36 extra-base hits (including 22 home runs). That’s a much taller order.
To put the sheer magnitude of that task into perspective consider this: in 147 plate appearances with AA Harrisburg, Bryce Harper posted a wRC of 18. Normalizing that to the 600 plate appearances one might expect to see out of an every-day player, that would have given Harper an expected wRC of 83.72. Harper would have to hit major-league pitching better than he hit AA pitching to even have a chance of doing no harm to the team in this situation.
Fangraphs’ RotoChamp projection sees Harper with 259 plate appearances in 2012, projecting a wRC of 36 from those plate appearances. Even if we normalize this to 600 plate appearances, that only gets us to 83.39 wRC–not quite good enough for our purposes.
That’s how good Bryce Harper has to be. The real question is: how good is Bryce Harper? Only he can show us if he’s as good as he has to be. For the sake of Nats fans everywhere, I hope he shows us he’s much better than even that.
