Annex wood bat Model 13 is similar to the AM11. The difference is that we have designed a power hitting model for players that like to hit for average. By slimming the barrel a fraction and shifting the center mass towards the handle to create a less barrel heavy feeling. The AM13 wood bat is cut from our most dense maple wood. The more dense the wood is the stronger and better the wood bat will preform. We have compacted this model into a flawless design, giving it wicked strength, delivering power to every style of hitter. Try the AM13 out today!
