What is the Approximate Torque on a Baseball Bat Held Horizontally?

[disque]

Homework Statement

A baseball player holds a bat at the end of the handle. If the bat is held horizontally, what is the approximate torque due to the force of gravity on the bat, with a pivot point at the batter's hands? Assume that the the bat is uniform. Use L for length of the bat, m for mass and g for acceleration due to gravity.

Homework Equations

t=d(lever arm)F

The Attempt at a Solution

I thought it was just lmg and that was wrong so I tried lm-g and that was wrong as well so I don't know what I'm doing wrong. Any help would be appreciated!
