The Towel Drill: A great drill for killing rotational power
I almost included the towel drill in my list of least favorite pitching drills, but decided this one needed it’s own separate article. The most common version of the towel drill involves performing your motion with a towel in your throwing hand with the intention of hitting a target that somebody holds out in front of your landing foot. The idea is in order to consistently hit the target, you need to demonstrate good extension, balance and posture. Unfortunately, it can also lead to some very bad habits if you’re not careful.
In my opinion, the towel drill, at best, can be a useful tool for teaching proper sequencing in your delivery… at worst, it can create awful mechanics that actually rob you of power and velocity. If not taught or practiced properly, it trains the pitcher to “reach out” or stride farther, which tends to cause them to open early and lose rotational velocity (hip and trunk rotation are two of the biggest contributors to velocity). As I discussed in a previous article, a long stride does you no good if you open early with your hips. If you want to maximize power and velocity, you need rotational power.
Focusing on hitting a target out in front of your foot doesn’t make much sense when you consider a pitcher’s actual release point!
Despite lumping the towel drill in the “drills I don’t like” category, I do see some value to working with a towel. Developing a powerful pitching delivery that you can repeat consistently takes work – it can take over 1,000 repetitions to really ingrain new movement patterns. Throwing drills and pitching off the mound should make up a good part of that work, but sometimes it’s helpful to work on your pitching mechanics without a ball.
Working without a ball saves wear and tear on your arm, and also makes it easier to focus on your mechanics since you’re not worried about where the ball is going. Using the towel can be helpful because sometimes when you perform full speed reps with nothing in your hand it can feel like your arm’s going to fly off.
So I’m not against working with the towel, it’s really just the intention of the drill I have an issue with. Here is a great video of major league pitcher George Kontos (fellow Northwestern grad, incidentally) using the towel to work on his delivery. You’ll see there is nobody standing in front of him holding out a target for him to smack.
Notice his late trunk rotation! He is basically just working on his mechanics with a towel in his hand. When I was in the minors, a lot of guys would use a towel to work on their mechanics before the game. But the goal was always performing quality reps of their motion, not smacking a target in front of their foot. Bottom line, I’m not a big fan of it, but if you’re going to do the towel drill at all, do it this way.
