In Matheny's years as manager he's benefited tremendously from the groundwork laid before him, but he is an awful on field manager. His apparent obstinance in the face of common sense is Dusty-esque. I thoroughly enjoyed him repeatedly going to lefties to face Rizzo in the playoffs last year in the face of every statistical indicator that it was a stupid idea. I'd still rather have him face a lefty if I were the opposition. The problem is that Siegrist is pretty terrible vs. lefties
