Why is the quality of american pitching so poor?

Jim asked and added:

"This is evident by the fact that tanaka, a guy who hasn't thrown a pitch here is expected to be handed an enormous contract. Teams are desperate for quality pitchers. We develop so few."

my response:

Without sounding like I'm brown nosing, you've actually brought up a valid point. When 50% of starting pitchers are injured during the season, that sends up a red flag to people that are having to pay the bill...so to speak. The Orioles are to be commended for being the first organization trying to decrease the number of injuries to pitchers in their organization. From the bottom to the top levels, each pitcher is now filmed and analyzed with bio-mechanical software to correct and polish deliveries to reduce injuries and lengthen careers. I have to point out that the new software being used has come a long way since Tom House's. As an alternative to bio-mechanical software, a few organizations are using the OIP Pitching Mechanics Evaluation tool to determine injury probability. I won't name names because I don't want to jeopardize a person's career, but Tanaka had a 47% OIP. That is considered very risky for a long term investment. Top pitchers with very sound mechanics like Kershaw, Verlander, and Cliff Lee have an OIP of 10%...just because injuries happen in baseball...sometimes from playing flip or slipping on a step in the dugout and not just from a throwing wear and tear related injury.
