Launch Quality in hitting refers to how well and, in particular how quickly, a hitter gets the barrel up to speed once they decide to swing at a pitch. High Launch Quality is important because it enables a hitter to start their swing as late as possible.

Leaky Hands is an example of a flaw that reduces Launch Quality in hitting.

Launch Quality

Ronald Acuna struggled, when he first played at the MLB level, because of a Launch Quality problem.

Rather than exhibiting a Sudden Start, Acuna instead demonstrated Leaky Hands.

Impresssively, and as I discuss at length in my analysis of Ronald Acuna's swing, Acuna fixed this flaw over the 2018 All Star Break.

Launch Quality is related to the topics of...

• Hitch in the Swing
• Short to the Ball
• Leaky Hands
• Sudden Start
