Balk??

[spots101]

About a month or so ago I posted a situation/question about the pitcher throwing to a player (F6) who was not close to the bag in an attempt to retire a runner. The responses basically said that it was not a balk unless it happened at first base.

Here is my new and related question. Right-handed pitcher in stretch position. Bases loaded and the runner on second has a sizeable lead, in close proximity of F6. The pitcher steps directly to 3B and throws to F6 in an attempt to tag the runner. Obviously the pitcher must step towards the base he is throwing but what about throwing to a fielder? Could this be considered a balk?
