Average League Lines & Ages

Matt Eddy at BaseballAmerica published a very informative piece today dealing with the average slash lines, stats, and ages of each league in 2009. This stuff is very helpful when comparing players across leagues, so I really encourage you to read the whole piece, but here are the slash lines for each Rays-relevent league, along with the average age for each level:
Level - League                  BA    OBP   SLG   OPS     Age
AAA - International League .262 .328 .395 .723 26.9
AA - Southern League .255 .332 .380 .712 24.3
High-A - Florida State League .252 .322 .363 .685 22.8
Low-A - South Atlantic League .254 .324 .368 .692 21.6
SS-A - New York-Penn League .245 .320 .351 .671 20.8
Rk - Appalachian League .257 .328 .384 .712 20.8
Rk - Gulf Coast League .238 .316 .335 .651 20.5
A few quick observations: In regards to the Gulf Coast League, the average GCL/AZL pitcher was more than a year older than the average hitter(weighted for playing time). The FSL's average OBP was the lowest of any full-season league at .322, and the Stone Crabs had the league leader in Shawn O'Malley, who got on base at a .388 clip. He also played the season roughly a year younger than the average hitter's age. He hit for virtually no power at all -- a well-below average .311 SLG -- but he's really worth keeping an eye on in the Arizona Fall League in a few weeks.

This information is really nice to have, and I hope I can play around with it some more. If you click the link to the actual BaseballAmerica piece, there's also information like walk and strikeout rates, so it's worth checking out.
