Ask Rotoman: Zack Greinke or Mark Melancon?

Rotoman:

Only 4 pitching categories in my keeper league. Wins+Saves is one category…Greinke or Melancon?

“Volatile”

Dear V:

My 5×5 projections for both Greinke and Melancon are worth $17 this year, so I thought this would be an easy one to answer. Combine the value of the Wins and Saves for the pitchers, divide in half, and replace the values of Wins and Saves with that number and bingo. Or voila! Or eureka!

Instead, I’m not sure. I used the Razzball, FanGraphs and Patton $ Online value calculators on whatever projections they used (Grey Albright, Steamer, Rotoman) and found that though the numbers they spit out were different, all favored Greinke. In order: $10.4/$8.2, $7.6/$1.9, $10.1/$7.55.

Fangraphs clearly punishes relievers more for their lack of strikeouts, but I’m sure a closer look would show they’re rewarded more for their low ERA and Ratio. Razzball and Patton were close enough to declare a winner, but I was nagged by the question of population. You see, pricing systems are based on the performance of some group of players. In the regular 5×5 world this means one thing, but when you make guys who get saves more valuable, as you do when you combine saves and wins, the population changes. That changes the value of an earned run, it alters WHIP, it means a strikeout is worth something different.

So, I ran the numbers on last year’s stats using my own pricing calculator.

Last year, in 5×5, my pricer says Greinke earned $21 and Melancon earned $19, Combine Wins and Saves into one category for all ML pitchers, re-sort, and their prices change to $21 and $20.

Which means, if you agree with me that they’re each worth $17 this year, that Melancon gains a little edge in value over Greinke using your rules.  But prices didn’t change as much at the high end as I expected they would.

Of course, value is only part of the equation. Keeper questions start there, but always come back to what the guy is going to go for in your league. You want to keep the one you think is going to cost more. That’s a question only you can figure out.

Sincerely,
