Steve Sommer of Gashouse Graphs interviewed Cubs F/X mastermind Harry Pavlidis last week. Harry's a bright guy -- and the absolute best man to answer pitching questions. Here's a sample of the interview:
[Starlin Castro's] error total is a big concern. Sailing throws well over the or around the first baseman has become a habit. He’s also made some ill-advised throws to other bases. He can hit, the power will come. He can run well enough, not a big part of his game. He has excellent range at short, and his arm strength is fine. If he can get over this Steve Sax thing quickly he’ll be fine. Quickly, as he’s not in a very patient environment.I hope he's right.
