In GTA IV, the Baseball Bat can be purchased at the back-alley gun shops for $5. It cannot be purchased from Little Jacob. This is a pretty good weapon for attacking people at point-blank range, but the knife is better. This is about a 3 or 4 hit kill and can break windows also. In The Lost and Damned, the bat is used to hit other racers in bike races. If you time your attack right and keep a distance while confronting someone, you can swing a lethal direct hit to the head which can knock out, or even kill, the person you're fighting. In GTA IV, The Lost and Damned and The Ballad of Gay Tony, if timed properly, when the player swings the baseball bat (the swinging move that's done when someone isn't targeted), sometimes the gun of a person can be knocked out of their hands. This is a similar move to disarming, but with guns. Players should be cautious that if they were to do this, they must be in front of the person aiming the gun and this can cause injury to the player. The chance off knocking a gun out of a person's hands is bigger with pistols and submachine guns, because of their lightness. The Baseball Bat can also be used for a one-hit kill counter-attack, by dodging an attack with the Bat equipped, and pressing the attack button.
In Chinatown Wars, the baseball bat is a wooden one and unlike the nightstick, it knocks people to the floor, which leaves some time to kill them while in the ground.
In an early version of GTA IV, a wooden baseball bat appeared, as well as GTA SA. In the first mission in GTA SA, the bat that Big Smoke is holding appears to be wooden, instead of the aluminum one available in-game. Also, in the mission Running Dog, Big Smoke is again seen using a wooden bat to knock out a Vagos gang member. It clearly produces a wooden sound when Big Smoke drops the bat.
In an artwork for Grand Theft Auto V, Franklin is seen with a dog, using a chain as a leash. He is also seen holding a bat. This one is wooden like in GTA III, GTA: Vice City, GTA Advance, and GTA Chinatown Wars.
