First, here are the definitions of the stats used from the StatCorner Glossary:
xIP: Derived from xOuts, "xOuts stands for the expected number of outs a pitcher has generated based on his defense and park neutral outcomes." This is how much they pitched.
tRA: "tRA involves assigning run and out values to all events under a pitcher's control and coming up with an expected number of runs allowed and outs generated in a defense and park neutral environment. tRA is on a R/9 scale and does not involve any regression of the rates so while it should be more useful at determining a pitcher's true talent level, the best method for pitching projection is to use tRA*, the regressed version of tRA." This is how well they pitched.
pRAA: "Stands for pitching runs above average. Using tRA as the benchmark, the formula is (lgTRA * xOuts / 27) - xRuns." This is how much 'value' they added (or cost) their team based on the quality and quantity of their pitching.
Notes: StatCorner only covers down to full-season A ball, so no Hudson Valley, Princeton, DSL or VSL players. Data doesn't include innings pitched as a reliever, only as a starter. Age is as of today. Spot starters aren't included. Pitchers are listed by level, so for example Hellickson and Price appear on multiple lists.
Tampa Bay Rays (MLB):
Sonnanstine was nearly as valuable as Shields and yet there are those who want to trade Sonnanstine and keep Jackson. When Price is added to the rotation next year Jackson clearly needs to be the one to go, either to the pen or in a trade. Garza and a (hopefully) healthy Kazmir will round out the best rotation in the majors.
Durham Bulls (AAA):
Similar to Sonnanstine vs. Jackson, in the debate between Talbot and Niemann, the wrong one (Talbot) usually loses. I know Niemann was a higher pick and is a huge, projectable guy, but Talbot was much better in 2008. If we have to trade one, I'm hoping it's Niemann. Davis will get a full season of AAA next year, barring a callup. Cummings and Hendrickson are just filler.
Montgomery Biscuits (AA):
|De los Santos, Richard||24.4||AA||70.6||4.91||-0.8|
Davis was better in AAA. Hellickson and Rollins should start the year in AA, Houser in AAA. McGee will miss most of the year, and De los Santos is a free agent.
Vero Beach Devil Rays (A+):
Hellickson and Price just dominated, and Rollins was solid. Walker has a make or break year coming up following the suspension. Mann and Morse are filler.
Columbus Catfish (A):
This is why I'm not as high on Cobb as most people. He is young, but he'll need to improve at Charlotte next year to convince me he's one of our top pitching prospects. Darcy did well after beginning the year in the pen, but because of age he needs to move quickly. Ragan was released. Hall and Flores are filler, actually Flores may have a future out of the pen as a LOOGY. Gibson was so bad he lost his spot in the rotation, was even worse out of the pen (8.07 tRA), and was demoted to Hudson Valley. As I wrote in early September, forget 2008 happened and start over in Bowling Green in 2009.
To summarize, with the addition of Price we will have the best starting rotation in baseball to begin 2009. But, as the need arises, we have plenty more talent on the way. The problem will be finding room on the big league roster, but what a great problem to have. As injuries occur and players are lost to free agency, spots will open up. And not all of our prospects will make it because of injuries, trades, or just hitting their ceiling in the minors. With any kind of offense, the Rays will be a formidable foe for years to come in the AL East.
