OIP: Overall Injury Probability

Overall Injury Probability is a scouting evaluation tool in the use of grading pitching mechanics in an objectively, subjective manner. The main movements involved in a pitcher's delivery (leg extension, hip rotation, and follow through) are numerically rated to establish a baseline. Other problems in the delivery (i.e., short arming, poor balance, throwing against the body, etc.) are then factored in if present.
An injury probability percentage is easier to read and understand when presented quantitatively for evaluating amateur, free agents, and potential trades.

Texas Rangers' Newly Acquired RHP Matt Garza

Well, as the old saying goes, there's good news and there's bad news. The good news is that he still has a fairly live arm and the Rangers have a shot at resigning him, but the bad news is that he he has some mechanical issues that causes him to fatigue and lose arm strength before he reaches a 100 pitches in his starts.
In the evaluation of his big three of pitching mechanics...leg extension, hip rotation, and follow through. Matt shows a minus 25 hip rotation which means he's using his arm almost exclusively in his delivery when he steps open after his leg extension and throws before there's any hip rotation at all. Pitchers with this flaw usually develop scar tissue in the rotator group of their throwing shoulder which in turn reduces their velocity. You can add an inconsistent follow through to his mechanical woes, as well...though not as severe as his lack of hip rotation. He only loses 5 points in this category. To sum it up, Matt will have a 30% probability of injury this season with a year or two left in his arm before scar tissue catches up with him.

OIP (Overall Injury Probability): 30%

Cuban RHP Miguel Alfredo Gonzalez

The Cuban defector is currently pitching in the Mexican League, but has dreams of signing a contract with a MLB team next week. He has desires of a big offer and is said to be seeking a six year deal in the range of $60 million.

It'll be interesting to see which MLB organization signs him, if any, for the amount he wants since he's a project pitcher with the mechanic problems (OIP grades in parenthesis) and habits that he has with leg extension (-10), hip rotation (-25), and follow through (-10). Gonzalez graded out with an OIP (Overall Injury Probability) of 45%.

His fastball is in the mid 90s which may make some organization willing to take a chance on him anyway. 

UPDATE: The Phillies have fallen for the hype and just beat out the Red Sox and their offer for Gonzalez. 

That's a quite a contract for a project pitcher with the mechanic problems he has with leg extension (-10), hip rotation (-25), and follow through (-10)
Gonzalez graded out with an OIP of 45%. May the Phillies' player development have success in transforming him before this pitcher develops velocity killing scar tissue in his rotator group.
