Introducing ATB Diamond Vision

Diamond Vision is a graphical depiction of the overall value of each player. It is based upon the percentile the player falls into for a specific category. For example, the person with the best OBP is in the 100th percentile. Diamond Vision is calculated using four groupings of statistics - On Base, Power (in the form of ISO), Base Running (in the form of DMB ratings for Steal, Jump, and Running) and Defense (in the form of DMB range rating).

The idea for Diamond Vision was pirated from two sources - Mike S, owner of the Lusitania Death Speakers and the good folks at
Beyond the Box Score . Mike provided the general idea when trying to the same for his rec Hockey League and BtBS provided much of the methodology speceific to baseball. Thanks!

Each week we'll feature a new player, but to start I'll cherry pick a few of the more interesting ones.

Best Overall Skills
Mickey Mantle is currently the best all around player in the game today. On offense, hee has a well above on base percentage of .380 and hits for plus power. His base running is among the best in the game with Ex scores in Steal Success and Running, while only hampered by his relatively low steal attempt rate. His defense in Center Field is also Vg.


Best Batter
Lou Gehrig currently leads the league in OPS and ATB Value. However, without great base running kills and 'only' average defense, his Diamond Vision chart is heavily skewed to the right



All Power
Mark McGwire is currently 3rd in the league in Home Runs but is a poor base runner and average defender. I thought Jim Thome was a good version Big Mac light too.



Best On Base

Gotta love John McGraw. Awesome on the base baths and getting on base, but absolutely no power to speak of whatsoever. He leads the league with a .465 OBP but has just 6 extra base hits all season long. Gehrig has 59.


All Speed
How about John Ward. Great on the basepaths - 33 SB, decent on base at .359, but not a lick of power to be seen.



All Defense
Luis Gonzalez has made 482 plate appearances for John McDonald, and defense must be the reason. He is an Ex defender but batting just .247 / .313 / .400.


Not Much Going on Here
Hey, as much as we love defense in ATB, does a Vg defender who is batting .265 / .310 / .319 really deserve 430 plate apperances?
