The changeup is a deadly weapon at the major league level: Entire careers are made (Jamie Moyer) or destroyed (countless starters who couldn’t master one) as a result of the pitch. Change-ups are typically 10-15% slower than a pitcher’s best four-seam fastball he’ll use in a game and will have both arm-side run and sink to it. The result is a pitch that changes both speeds and locations while having a similar trajectory to a four-seam fastball. It’s best used to mitigate platoon advantage (and in some cases, completely neutralize it – see also Shaun Marcum’s three-year reverse splits) so starting pitchers can get opposite-handed batters out.

It’s common knowledge that batters who face opposite-handed pitchers (right-handed batter vs. left-handed pitcher, for example) have an advantage compared to facing a same-handed pitcher. The changeup helps swing that advantage back in the pitcher’s favor by giving the hurler a pitch that moves away from the batter, since their breaking ball will typically move towards an opposite-handed hitter.

Coaches rush to teach the changeup to youth pitchers because they believe it’s safer on the elbow and that it’s a great pitch to master early. It’s true that changeup kinetics are lower than breaking balls and fastballs in a typical pitching delivery, so the safety argument probably holds some water. However, there are three major problems with teaching a changeup to youth pitchers, and they are:

Youth Hitters Aren’t Like College and Pro Hitters

Young baseball hitters – even ones in high school and even college – don’t have efficient hitting mechanics like most professional hitters do. How many times have you gone to a high school or Little League game and saw hitters completely swing through fastballs for strike three? This simply does not happen at the professional level. In 2010, the “whiff rate” (swing and miss) of the top 25 pitches were all breaking balls and off-speed pitches. The best whiff rate was Cole Hamels’ changeup at 48%, while the best fastball whiff rate was Takashi Saito’s at 37.4%. (source: Beyond the Box Score)

You might be wondering how using Hamels’ outstanding changeup is proof that the changeup has problems at the youth level. The reason is as I stated before: Hitters get good fastballs blown by them extremely often at the youth level. This is primarily due to the fact that most youth hitters have inefficient hitting mechanics and improper loading sequences that causes them to be late to most fastballs. Many young hitters have a severe case of “bat drag,” where the elbows lead the handle of the bat into the hitting zone, causing a very long, looping swing.

When you throw hitters like this a changeup, you are doing them a favor! You speed up their bat, allowing them to make solid contact. Pitchers in the big leagues throw off-speed pitches and breaking balls after they’ve set up their fastball command. There’s a reason that scouts primarily want to see good fastball velocity and good fastball command – these two factors matter the most as you move up the levels in pro ball!

The Changeup Cannibalizes Fastball Velocity

Paul Nyman made this observation many years ago, and I agree with him wholeheartedly. Youth pitchers who rely on a changeup and throw it often in their bullpen sessions will often change their throwing mechanics to get better sink and velocity separation off their fastball. As a result, their pitching mechanics become highly linear and their arm speed decreases due to poor use of rotational force, and this loss of velocity creeps into all of their pitches, including their fastball.

This argument dovetails nicely with our motto at Driveline Baseball, which is that pitchers must throw often and not necessarily pitch often. The two skills have a lot of overlap, but as Paul said a long time ago, you can throw a ball without pitching it, but you can’t pitch a ball without throwing it. Pitchers must master solid throwing mechanics as they develop over the years, and by focusing too hard on things like throwing strikes and developing off-speed pitches, they will never develop the elite velocities they need to pitch against post-high school competition.

Improper Focus on Getting Hitters Out

Mastering a reverse breaking ball (which a changeup more or less is) is a great way to help yourself get opposite-side hitters out. There are two major problems with this at the youth level:

  1. If you’re a right-handed pitcher, you will face a staggeringly large percentage of right-handed hitters
  2. If you’re a left-handed pitcher, your uniqueness is usually good enough to neutralize the platoon advantage

So if you’re a right-handed pitcher and you spend your time developing a pitch to get lefties out, you aren’t even focusing on what is most important to get the majority of hitters out that you’ll face in your high school career! Fastball velocity/command are the most important, followed up by breaking ball quality/command. Your off-speed pitch comes much, much later down the line.

Left-handed pitchers tend to focus too much on deception (varied arm angles, a possible injury indicator) or craftiness (throwing change-ups or other off-speed pitches) to get right-handed batters out, rather than simply developing two fastball variants (two-seam and four-seam) and the ability to locate hard fastballs to both sides of the plate and in three vertical locations – up, middle, and down.

Pitch Tracking

So, is the Changeup Bad?

No! Of course it isn’t. However, it’s not the end-all be-all of pitches that youth pitchers should learn to throw. Contrary to what most people will tell you, fastball velocity is still king, while fastball command is the prince. Colleges and pro organizations want to see big fastballs out of solid-bodied pitchers, and they want to know that you can command it to multiple locations to set up your other pitches. Remember, the better your fastball is, the better your other pitches become automatically!

A good training program will take all of these factors into consideration and develop a comprehensive pitching (and throwing) program for progressing athletes regardless of their level of competition.
