To keep him long term. You aren't going to be able to low ball players like that anymore. Look at the contract Freeman got. It's exactly like this what I proposed for Minor. To get any sort of real discount on a players free agency years you will need to sign them a year or two after they have been in the majors like we did with Julio and Simmons.
And if you let him go year to year then there is virtually no way to keep him long term without paying then current market value which will likely be higher.
Freeman imo projects to be 1 WAR per year better than Minor. So if you want to use Freeman as a baseline (and I actually think we should require a bigger discount from Minor but lets set that aside) you need to scale down Freeman's free agency years salary down by about 6M per year to get comparable value with Minor. In addition, the numbers you propose in Minor's last arb year just looks to high relative to his open market value.
