| Model code | MT27 |
|---|---|
| Wood | BirchWhat this meansSofter than maple and more forgiving of mis-hits; hardens with use. A good choice for a first wood bat and for younger players. |
| 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. |
| Barrel | Long, Large, 2.46"What this meansThe middle of the range (about 2.45 to 2.55 in). Most pro turn models live here. Tip: A safe default when you are not sure. |
| Handle | Thin, 0.92"What this meansA handle under about 0.93 in. It whips through the zone and feels fast, but it stings more on mis-hits and, in wood, breaks more easily. Common on pro models. Tip: Thin handles and young hands do not mix well in cold weather; expect sting. |
| Knob | Other |
| Balance | End loadedWhat this meansExtra weight toward the end of the barrel, so the bat swings heavier than its number. For some players it gives a better feel for where the barrel is; whether it suits yours depends on how consistently they deliver the barrel. End load is not barrel size: some skinny-barrel bats are end-loaded. Tip: An end-loaded bat that feels heavy is the most common sizing mistake we see. |
| Lengths | 31, 32, 32.5, 33, 33.5, 34 in |
| Ink dot | YesWhat this meansAn ink dot on the handle shows the maker tested the grain slope. It is required for maple and birch bats used in pro ball and is a good sign of wood selection on any bat. |
| Finishes | Matte Navy; Clear Handle/Matte Navy Barrel |
| Certification | Ink-dot certified (MLB Approved) |
| Warranty | 45-day warranty included |
