2010 Performance Evaluations – Southern League Pitchers

Teheran’s SOL Performance may be enough to vault him to the top of the pitching prospect lists

Moving over to the pitchers of the Southern League, we continue our annual examination of Performance for each of eighteen Minor Leagues that have affiliations with MLB organizations. Over the next two weeks we will finish posting the Performance analysis for approximately three leagues each week until we have run through them all. The Braves dominated this list, placing three pitchers in the top seven and four in the top twelve, but none was better than teen sensation Julio Teheran. Teheran fanned 38 in his 40 innings of work, and easily out-distanced the Mariners’ Michael Pineada and teammate Randall Delgado. And if you haven’t heard much about the fourth place finisher on the list, Rubby De La Rosa—you will. De La Rosa hit 100MPH multiple times in his SOL work.

A couple of things to remember about our Performance evaluations: 1) these are not necessarily prospect lists. While it is fair to assume that the best prospects will put up the best performances, these lists focus only on a player’s offensive performance while they were in the league during the 2010 season. They do not consider things like defensive ability, offense vs. required offense for a given position, or projectability. Prospect evaluation is a combination of art and science and this is the science part of that equation. Later in the fall, we will breakdown each team’s ‘prospects’ and rank them in ‘prospect value’ order. 2) What it is, is a comparative statistical look at each players performance, placed in context of their age, their home park, and the league. We rate each player in the five categories that we have found most significant in predicting future Major League performance. The players that rate the highest, have assembled the best ‘Performance’ in these areas. For a more detailed look at the statistics involved you can refer to previous articles on the site (http://baseballnumbers-diamondfutures.blogspot.com/2009/09/do-it-yourself-quantitative-examination.html).

A quick note about the rankings…The TOTAL is the weighted numerical value of the combined statistics that we use. It is scaled for the level of play. Typically, a player with a positive score will rank in the top 1% - 2% of all Minor League players. After the total we list the sub-scores in 4 areas of significance. These scores are presented, for ease of understanding, in a typical 20-80 scouting format. They represent how the individual player performed in those areas in relation to THE LEAGUE in question. A score of 50 represents league average. Players listed as ‘DNQ’ did not qualify for the rankings because of their limited playing time, but we felt their scores were worth noting.
