Why we’re high on Mookie Betts’ trade value

Here at BTV, we sometimes find ourselves going against the grain when it comes to popular opinion. We seemed to be the only ones who thought Corey Kluber [2.7] , Nomar Mazara [0] , and Omar Narvaez [6.0] wouldn’t fetch much in trade, and we were right.

But sometimes we’re on the opposite side of the fence. Popular opinion (at least, if you go by what media pundits have been saying) seems to be that Mookie Betts [50.7] wouldn’t return a whole lot either. We disagree. Most of these pundits cite two things: Betts has only one year of control, and he’s predicted by MLBTR to make $27.7M. That’s already a lot of salary for one year, right? Yes, it is. Which means there’s not much surplus value, right?

Wrong. We think there’s still a lot of surplus.

Mookie Betts is not your average Arb3 player. He is elite, second only to Mike Trout [137.9] when it comes to production. Over the last five years, Betts has put up a whopping 35.4 WAR (exactly the same as measured by both fWAR and BWARP), including a remarkable 10.4 fWAR in 2018. Steamer projects him for 6.6 fWAR for 2020, and that may be conservative.

Using our weighted average approach to WAR systems, which also includes key peripherals, we estimate him for 7.8 WAR for 2020. This is partly due to the fact that he’s still young — he’s coming into his age-27 year, which is typically the first year of peak performance. That’s right: we haven’t even seen Peak Mookie yet.

Further, he carries little injury risk, since he’s proven to be quite healthy and durable. At age 27, our injury-risk discount for position players is only 16%, which means our adjusted WAR projection is 6.6. Translating that to dollar value, that comes to $62.7M in AFV. Against a salary of $27.7M, that leaves us with a surplus of $35M.

But that’s not all. If Mookie is traded this offseason, the acquiring team will also get the additional hidden value of the draft pick, after Betts is offered (and most assuredly would decline) the qualifying offer after the 2020 season (note that this only applies if he’s traded now, because to get the QO, a team has to carry that player for the full year; therefore that value wouldn’t exist if Betts is traded at the deadline). We estimate that at $9M (note that this varies due to a number of factors, so it’s a rough average). So now we’re up to $44M in surplus.

Additionally, Mookie, being a superstar, comes with great marketability — any team that acquires him figures to sell more tickets and merchandise with his name on it. And as with most elite players, we expect him to go towards the higher end of his range, not the middle. Conservatively, we’ve added only $6M to account for both of these factors, which is why we end up at $50M as the median.

Further, we may be underrating him due to position. Betts has been putting up those WAR numbers playing mostly in RF, which comes with less of a positional benefit than if he were playing CF (as Trout does) or SS (as Francisco Lindor [63.4] does). If a team traded for him to play center, he’d likely produce even more because of that adjustment. 

We also shouldn’t forget Betts is coming into his walk year — when players typically turn it up a notch to improve their chances for a rich contract in free agency.

Lastly, Betts is the type of player who can move the needle — for a team like the Dodgers, who are desperate to get over the hump and finally win that elusive World Series; or a team looking to make a splash and finally get into the playoffs after multiple losing years (like the Padres or Reds). There is marginal-win value to those teams, and they shouldn’t be afraid to pay the price for him in trade as a result.

So for those who think one (not-cheap) year of Betts won’t return much to the Red Sox in trade, we think otherwise.

    I wish you could do a value adjustment based on team. For instance, the value of Betts to the Dodgers should be higher than that of, for instance, the Athletics due to their ability to resign him. Also, based on positional need where Clevinger to the Angels would be a higher value than to the Nationals do to need in that area.

      We get this comment a lot. We’re considering that type of thing as a future enhancement. However, it’s very tricky as it could potentially involve a lot of complex game theory to get it right. For now, we simply supply a low/median/high, and set expectations that some teams will overpay and some will underpay relative to that median based on their needs and budgets (and let users comment on how that might work for their specific teams). In any case, yes, that’s something we’d like to enhance going forward.
