Runner forced off of legally attained base

[PandaBear]

Or a mistake was made. It was officially scored "E1 - advanced to second on a throwing error by p, failed pickoff attempt." It was a failed pickoff attempt, but F3 caught the ball, and had it in his glove until he tossed it back to F1. It was not called or scored a balk (that happened in another inning, at another base), and a balk is not scored an error.
