12-10-2010: Revised projection for Adrian Gonzalez

Alright, I’ll admit that the first projection I put up was a little too conservative. It’s because I was using a flat adjustment for the NL to AL transition. Works well for average players, doesn’t work so well for superstar players. I’ve adjusted my methodology to a component-correlated one, and used it as a basis to regress towards 50%. Using this new method, here’s what I get for Gonzalez in Fenway:
| Age | AB | H | 2B | 3B | HR | R | RBI | BB | SO | SB | Avg | OBP | SLG | OPS | wOBA | wRAA |
| 29 | 606 | 175 | 39 | 1 | 30 | 98 | 105 | 81 | 121 | 2 | 0.289 | 0.378 | 0.505 | 0.883 | 0.392 | 46.2 |
| 30 | 615 | 176 | 38 | 1 | 30 | 98 | 106 | 80 | 122 | 2 | 0.287 | 0.375 | 0.501 | 0.876 | 0.389 | 44.6 |
| 31 | 617 | 175 | 37 | 1 | 30 | 97 | 106 | 78 | 121 | 2 | 0.284 | 0.370 | 0.495 | 0.864 | 0.384 | 41.2 |
| 32 | 612 | 172 | 35 | 1 | 29 | 95 | 103 | 74 | 118 | 2 | 0.281 | 0.363 | 0.485 | 0.848 | 0.377 | 36.0 |
| 33 | 600 | 166 | 33 | 1 | 28 | 91 | 99 | 68 | 114 | 2 | 0.276 | 0.355 | 0.473 | 0.828 | 0.369 | 29.5 |
| 34 | 580 | 157 | 30 | 1 | 25 | 85 | 93 | 61 | 109 | 2 | 0.271 | 0.346 | 0.459 | 0.805 | 0.359 | 21.9 |
| 35 | 552 | 147 | 27 | 1 | 23 | 78 | 85 | 53 | 103 | 1 | 0.266 | 0.335 | 0.443 | 0.778 | 0.347 | 13.7 |
| 36 | 517 | 134 | 24 | 1 | 20 | 71 | 76 | 45 | 95 | 1 | 0.259 | 0.323 | 0.425 | 0.748 | 0.335 | 5.5 |
I feel much better about this projection. One interesting thing I found was that even top sluggers who go from the NL to the AL lose a lot in terms of home run rate, and vice versa, for whatever reason. There’s a big difference once you change leagues, whether you’re Manny Ramirez or Matt Holliday or Mark Teixeira. That’s reflected here in Gonzalez losing 5 HR compared to his NL projection. I hope Adrian bucks that trend and hits 40, but it looks like the over/under number for 2011 is about 30.
