LOL, tehteh literally wrote, “Altuve is a reasonable comp for Albies“. So yes, the usual suspect used Altuve as an example of why Albies will be a 6 win player.
And yes, if someone says something stupid, I’m going to toss out an argument.
If you are going to extrapolate a player’s full season production based largely on his work in September on a terrible team...you’re doing something wrong.
Albies could very well hit his Top 5% outcome and post 6 wins, but nobody with any knowledge about baseball is projecting that for him.
Am I doing something wrong? Let's test it. I looked at the past 50 years of MLB and searched for 20 year old rookies, who, like Albies, came up later in the season (your garbage time argument), amassed at least 200 PAs, and had a positive WAR. Not surprisingly, there were only 4 such players, all of whom, like Albies, were on teams who weren't in contention. The four players are Jeff Burroughs, Garry Templeton, Terry Puhl, and Carl Crawford. I extrapolated their age 20 WARs to 650 PAs and compared that to their peak WAR years and their career WARs.
For each ballplayer I listed Actual age 20 WAR, age 20 WAR extrapolated over 650 PAs, (Three highest WAR seasons) and career WAR.
Burroughs: 0.4, 1.3, (4.0, 3.6, 4.6) 17.6
Templeton: 0.9, 2.6 (3.6, 4.3, 4.5) 27.6
Puhl: 1.2, 2.9 (6.2, 3.6, 3.5) 28.3. Sidenote: Puhl missed large chunks of several seasons due to injuries.
Crawford: 1.0, 2.3 (7.0, 5.0, 4.9) 38.9
Now lets look at Ozzie: His age 20 actual WAR was 1.4, the highest of the comps. His extrapolated age 20 WAR was 3.7, the highest of the comps.
All of the comps had seasons with WARs higher, and in some cases significantly higher than their extrapolated age 20 comps. The peak WAR seasons for the comps averaged 2.6 times their extrapolated WAR, ranging from 1,73 times their extrapolated WAR (Templeton) to 3.53 (Burroughs). Their career WARs averaged 12.71 times their extrapolated age 20 WARs, ranging from 9.79 (Puhl) to 16.91 (Crawford) .
Plugging those ratios into Ozzie's extrapolated age 20 WAR of 3.7, if he matches the lowest peak WAR ratio of the 4, he will have a peak WAR season of 6.4. If he matches the average peak WAR ratio of the 4 he will hit a peak season of 9.62. If he matches the highest peak ratio of the 4, he would have a peak WAR season of 13.1 (not happening).
If he matches the lowest career WAR ratio of the comps, Ozzie would have a career WAR of 36.22 and if he matches the average, his career WAR will reach 47.0. If he matches the highest, he would post a career WAR of 62.6.
NOTE: None of these numbers are predictions, they are simply illustrations.
But again, I ask, looking at the historical data, is it so unreasonable to see Ozzie having seasons in the 6 WAR range?
