No huge changes to the rating process this year, though I did make two fairly significant changes: better matchup data & a better representation of the average batter\/pitcher. I rated a total of 219 batters and 196 pitchers.<\/p>\n
<\/p>\n
Instead of relying on the MLB figures, I counted up all the PAs from last year’s TV games (both sides) and classified them according to match up. I included a separate category for switch hitters. Totals:<\/p>\n
\r\n LHP RHP\r\n --- ---\r\nLHB 282 752 \r\nRHB 434 790\r\nSHB 182 416\r\n<\/pre>\n(Total gives an average of 39.7 PAs per game per team.)<\/p>\n
How these translate to the ranking parameters for batters:<\/p>\n
\r\n$freq{'R'}{vR} = 0.645;\t\t# freq of R arms seen by R batter\r\n$freq{'R'}{vL} = 0.355;\t\t# freq of L arms seen by R batter\r\n\r\n$freq{'L'}{vR} = 0.727;\t\t# freq of R arms seen by L batter\r\n$freq{'L'}{vL} = 0.273;\t\t# freq of L arms seen by L batter\r\n\r\n$freq{'B'}{vR} = 0.696;\t\t# freq of R arms seen by B batter\r\n$freq{'B'}{vL} = 0.304;\t\t# freq of L arms seen by B batter\r\n<\/pre>\n…and for pitchers:<\/p>\n
\r\n$freq{'R'}{vR} = 0.403;\t\t# freq of R bats seen by R pitcher\r\n$freq{'R'}{vL} = 0.597;\t\t# freq of L bats seen by R pitcher\r\n\r\n$freq{'L'}{vR} = 0.686;\t\t# freq of R bats seen by L pitcher\r\n$freq{'L'}{vL} = 0.314;\t\t# freq of L bats seen by L pitcher\r\n<\/pre>\nLots of lefty bats in this sample. In 2007 MLB, righty pitchers saw 47% lefties. In the 2009 TV ABL games it was 60%.<\/p>\n
The second change was to use only the better players for the applied averages. Last year I used all<\/strong> the rated players to form the average. This year I took a guess at an ABL regular cut-off. I selected about the top 132 batters (12 per team). That put the cut off at Ryan Church. (He’s an approximation of the worst guy expected to get regular playing time.) I took the top 44 starters (4 per team), which cuts off at Kip Wells. Same for shorts, which cuts off at Chad Durbin. Allowed the top 11 closers, which is a cut-off at Chad Qualls. Didn’t have a good answer for weighting starters & relievers, so I threw them all together. As expected, the averages had a marked effect of lowering the ratings of everyone.<\/p>\n","protected":false},"excerpt":{"rendered":"
