Can someone explain to me exactly the meaning of grades for fielding range?
The grades range from A+ to D-. Logically, a grade of C would be the overall average for that position. C+ to A+ would be above average, C- to D- would be below average. Am I correct?
In the past week, I have had 2 A+ and 1 A range fielders make poor plays. 1976 George Brett (C/A) made a poor play. 2009 Albert Pujols (B-/A+) through the first 30 games had more poor plays (1) than good plays (0). 1970 Bobby Murcer (A/A+) had 2 errors and 1 poor play in the same game! And 1904 Nap Lajoie (C/C+) just completed a season with 1 good play and 5 poor plays. (That tells me C+ is well below average...unless 1+/5- is considered better than average?)
How can any fielder playing at 100% in his primary position with an A or A+ range rating EVER make a poor play? I would think that A+ rangers would have no poor plays even if they have a lot of good plays.
Also, other than creating more or fewer chances to make plays, do the salary cap, ballpark, or pitcher have any effect on range?
Thank you for your answers.
Fielding grades are simply graduations along the contium that is relative range factor (rrf). The higher the rrf the higher chance of a "+" play on any would be hit and the lower chance of a "-" play on any would be out. If you consider "average" as a balance between + and - plays, what is average obviously would depend on pitching, ballpark and the opposing hitters. As a rough estimate average in an OL is c+ to b- at most positions. An average CF is probably b+ to a- and at corner outfield spots average is about c-. RRF makes no practical difference at C.
Keep in mind performance is subject to luck. Just like a .330 hitter may out hit a .370 hitter, an a- fielder may outperform an a+ guy. The longer your guys play the more likely they will regress to their mean performance. Still outliers to happen.
Lastly keep in mind that fielding grades are only a guide. It would be a good idea to look at rrfs as well as fielding. You should also know the range of a+ rrfs is huge. When these players are employed optimally they are extremely effective at preventing runs.
