A team can non-tender a player for any reason, but it usually occurs when a team feels as if a player will make more through the arbitration process than they are worth.
Teams could have attempted to trade these players until last night's midnight deadline. It appears, though, when a player is non-tendered, a team could not get a fair enough package in return to complete a trade.
Holland, in particular, is an interesting case. The Royals did not own his rights past the 2016 season, which he will miss due to Tommy John surgery. By non-tendering him, they are not required to pay any salary to Holland next season and could re-sign him to a multi-year contract in free agency. This way, they would be able to have Holland on their roster when he returns from injury.
