2010 Performance Evaluations – Northwest League Pitchers

Padres’ RHP Keyvius Sampson made huge strides this season

We close out the Northwest League with a look at the pitchers, as we continue our annual examination of Performance for each of eighteen Minor Leagues that have affiliations with MLB organizations. Over the next four weeks we will post the Performance analysis for approximately three leagues each week until we have run through them all. Padres’ RHP led a solid group of NWL pitching talent that included the likes of teammate Adys Portillo and left-handers Edwin Escobar of the Giants and Miguel De Los Santos of the Rangers.

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.

2010 Performance Evaluations – Northwest League Hitters

Rangers’ teen sensation Jurickson Profar turned heads with his play in the NWL

Moving up to the Northwest League, we continue our annual examination of Performance for each of eighteen Minor Leagues that have affiliations with MLB organizations. Over the next four weeks we will post the Performance analysis for approximately three leagues each week until we have run through them all. The NWL was loaded with position player talent this season led by the Rangers’ shortstop prospect Jurickson Profar and Athletics’ first round pick Michael Choice.

2010 Performance Evaluations – Pioneer League Pitchers

The White Sox saw a Mark Buehrle like upside when they selected Holmberg in the second round in 2009

We wrap up the Pioneer League today, as we continue our annual examination of Performance for each of eighteen Minor Leagues that have affiliations with MLB organizations. Over the next five weeks we will post the Performance analysis for approximately three leagues each week until we have run through them all. The Pioneer League has some nice prospects scattered throughout the pitching list, but none of them turned in eye-popping performances this year, as the secondary stuff of David Holmberg garned the top spot. That being said, Kyle Lotzkar’s return from Tommy John surgery did turn some heads as he clearly over-matched PIO hitters in four starts.

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.

2010 Performance Evaluations – Pioneer League Hitters

There is a lot of projection remaining in the speedy Ortega who posted a .926 OPS in 2010

The Pioneer League is next up, as we continue our annual examination of Performance for each of eighteen Minor Leagues that have affiliations with MLB organizations. Over the next five weeks will post the Performance analysis for approximately three leagues each week until we have run through them all. Today we examine the Pioneer League hitters where the Rockies’ Rafael Ortega edged the Reds’ Yorman Rodriguez for the top spot.

2010 Performance Evaluations – Appalachian League Pitchers

The Twins signed the very slight Garcia as a 16yo out of the Dominican Republic in 2007

Moving over to the pitchers in the Appalachian League, we continue our annual examination of Performance for each of eighteen Minor Leagues that have affiliations with MLB organizations. Over the next five weeks will post the Performance analysis for approximately three leagues each week until we have run through them all. While pitching was down a bit in the APY this season, the Twins’ Matire Garcia edged out the Rays’ Enny Romero in what was likely the closest top score in any league this season.

A couple of things to remember about our Performance evaluations: 1) these are not necessarily prospect lists.

2010 Performance Evaluations – Appalachian League Hitters

In a league loaded with position prospects Oscar Taveras stood out

Moving up to the Appalachian League, we analyze the hitters with a look at our annual examination of Performance for each of eighteen Minor Leagues that have affiliations with MLB organizations. Over the next five weeks will post the Performance analysis for approximately three leagues each week until we have run through them all.

2010 Performance Evaluations – Gulf Coast League Pitchers

Maybe Jose Perdomo can parlay his GCL performance into a season like last year’s leader Adrian Salcedo put together in 2010

We finish up the Gulf Coast League today with a look at the pitchers in our annual examination of Performance for each of eighteen Minor Leagues that have affiliations with MLB organizations. Over the next five weeks will post the Performance analysis for approximately three leagues each week until we have run through them all. The pitching was a bit thin in the GCL this year, with few standout prospects.

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.
