I don't think this player is eligible for FA either due to being under 23 and not having a contract with MLB organization.
"International free agents under age 23 who have not signed a contract with a major league franchise as of July 1st of the previous year are NOT eligible for the regular free agent period. These international free agents will be part of the international free agency period beginning in July. International players over age 23 who do not have a contract with an MLB organization are regular free agents. While a major league contract automatically trumps a minor league contract regardless of value, no minor leaguer under the age of 23 may be offered a major league contract."
