| Model code | BO11 |
|---|---|
| Wood | MapleWhat this meansDense and hard, the most common pro wood. Hits hard and holds up when the player squares the ball up; breaks rather than flakes when mis-hit. Quality varies a lot by maker. Tip: Maple from a good maker is the best wood bat money can buy; maple from a cheap one is the worst. |
| Drop | −3What this meansDrop is length minus weight: a 30 in, 20 oz bat is a -10. A bigger drop number means a lighter bat for its length. Younger players use -10 to -13; USSSA 13U is usually capped at -5; high school and college are -3. Tip: Check the drop your league allows before you look at anything else. |
| Handle | slightly flared handle |
| Knob | FlaredWhat this meansThe handle widens into the knob like the bell of a trumpet. Players who choke up or want leverage like it; it also keeps the bottom hand from sliding off. Popular from high school up. |
| Balance | Slight end load |
| Lengths | 31, 32, 32.5, 33, 33.5, 34 in |
| Barrel end | Cupped |
| Warranty | 45 days |
| Lead time | 5-8 business days |
