That depends on both how he values a win, and how much that win is worth.
There has been a lot of agreement the past few years that a theoretical win in the marketplace can be valued in terms of actual dollars, and that the value is right around $9 million. (For anyone who is interested, you can find numerous articles on the cost of a win in free agency at Fangraphs.) So if Harris agrees with this concept, he might conclude that a player projected to get five wins in a year could be worth as much as $45 million for the year. Of course it’s doubtful that after this season anyone will offer Correa a 1/45, since the market is almost certainly not there yet. But this is an example of how Harris might look at Correa’s 5.4 WAR of this season and conclude that the Twins got their $35 million worth.
