Slowpitch Senior Softball leagues like SSUSA use a 1.21 Bat Performance Factor, which is simply the increase in the liveliness of a ball hitting a bat compared to throwing the ball against a solid wall. Approved bats must have the SSUSA/NTS logo or have a BPF of 1.21 or less.
At Closeout Bats we stock what we sell! We have a huge warehouse and are NOT drop shipping bats like many web sites. We update inventory and availability on the Web site several times a day as inventory positions change shipping hundreds and hundeds of bats. We also sell bats out of our physical store, so sometimes things sell out before we can get them off the Web site.
Limited quantities available. Prices subject to change without notice. Like we say, if it's on the site, it's in the warehouse -- just SOMETIMES it might have some other player's name on it! If you snooze, you lose, so ORDER YOURS NOW!
