Very Tough Call

Just how much surplus value these players might be worth is still a matter for scouts, yet even scouts differ on the outlooks of these players.

Baseball America, for example, ranks Riley #22 overall.  MLB Pipeline puts him #38.  ESPN’s Keith Law (insider subscription required) puts him #87.

BA also has Ian Anderson as the #2 prospect for Atlanta, right behind Riley at #24 overall (subscription required for full report).  Anderson is #30 on Law’s list, and #32 in the Pipeline.

Using this year-old chart, here’s the expected value of both players:

  • Anderson:  6.5 Wins Above Replacement, $32.2 million of surplus value.
  • Riley…
    • if higher ranked:  7.5 WAR (the more conservative figure was taken across the boundary) and $37.6 million of surplus value
    • if lower ranked:  4.2 WAR, $20.2 million
  • It’s reasonable to suggest that if the Marlins are more-or-less equating these players, they are opting for the higher Riley ranking internally; I’ll assume that going forward.

In addition, there is a ‘bust’ chance given on this chart:

  • Anderson:  42.2% chance of less than 3 WAR; 23.3% chance of 0.0 or less.
  • Riley:  50.5% chance of producing under 3 WAR; 32.1% chance of 0.0 or less.

We already have a track record for Realmuto:

  • 2015:  1.9
  • 2016:  3.7
  • 2017:  3.8
  • 2018:  4.8

Total:  14.3 fWAR.  There’s a lot of value there… proven value.

Now you can look at those numbers and suggest ‘Realmuto for 2 more years should beat those prospect estimates’.

That’s true:  he’s nearly 28, in his prime, and should be expected to throw 4+ WAR each of the next 2 seasons.  Ergo, the Braves should offer either prospect and more, right?

Well…. maybe…
