Perhaps next time the Twins have a first ballot hall of Famer in their system, he'll make it up before age 20. Also, keep in mind, that Kiriloff missed a full season. With another 600 plate appearances under his belt, he might already be on the big club. You may not personally like service time manipulation, but it's part of the CBA. It's negotiated. If you're in contention, and think a guy can help, you might risk burning that extra year of control. If you're not in contention, then getting that 7th season in the middle of a player's prime is the responsible thing to do.
