### Variables Affecting Trajectory and Distance

Let’s begin by examining each of the variables which determine the trajectory and distance a hit ball travels:

- Offset
- Centerline Angle.
- Pitch Trajectory (Descent Angle).
**Attack Angle**(click for how to measure attack angle).**Launch Angle**(click for how to measure launch angle).**Ball Exit Velocity**(click for how to measure ball exit speed).- Timing.
- Backspin.
- Horizontal Plane (Swing Direction).

__Offset, Centerline, and Descent Angles__

** **

**Offset** is the vertical distance between the centers of the ball and bat at contact.** **

**The centerline angle** is the line connecting the centers of the ball and bat at contact. “Squared-up” collisions are those where the attack angle is just under the centerline angle (image above). Near-optimal energy transfer from bat to ball, with some backspin, maximizes ball travel distance.

**Attack angle** higher (more upward) than **descent angle** is typical of power hitters. This is a home run with a 75+ mph (baseball) or 65+ mph (fastpitch softball) ball exit velocity.

__Attack and Launch Angles__

Launch angle is a vital topic for experienced baseball and fastpitch softball hitters. Yet, many coaches, parents, and players remain skeptical of the term, relating it to popping up or flying out. Others think launch angle is only relevant for home run hitters striving to hit for maximum distance.

But there are other definitions of “optimum” launch angle besides maximum distance. For example, the chart of MLB hitters (below) highlights the tradeoffs between adjusting launch angle to maximize batting average vs. slugging power.

#### Ball Exit Velocity (EV)

The most productive launch angle for each hitter is highly dependent on their ball exit speed. Therefore, the coaching concept is not to prescribe the exact attack and launch angles for all athletes. Instead, specify ranges based on exit velocity.

Experienced hitters need a basic understanding of launch angle and exit velocity metrics and how they relate individually. For example, let’s look at balls hit with launch angles in the range of 20 to 30 degrees as a function of exit velocity. At low speed, we have bloop singles, at high speed, home runs, and in between, an easy flyball out.

__Horizontal Plane (Swing Direction)__

There is more to the swing plane than vertical angles. The barrel’s direction through the horizontal plane is also central to ball travel distance and productivity. When the bat collides with the ball, the horizontal bat path is either in-to-out, out-to-in, or somewhere in between. When the hitter puts sidespin on the hit, causing the ball to curve and lose distance, the barrel has struck a “glancing” blow. To maximize ball exit velocity, the swing and extension path is through the pitch’s location.

Hitters should develop the skills and habits to work through the zone in-to-out and drive the ball towards the middle of the field.

### Optimize Launch Angle Concepts

*“There has been a shift in philosophy so dramatic it can safely be called a revolution, with more hitters, armed with better and more extensive data than ever, reaching the conclusion that not only are fly balls on average, better than grounders but that the latter are to be avoided at all costs.”** (These days in baseball, every batter is trying to find an angle, 2017)*

*“There is room for plenty of old school philosophies in baseball, but it is time we quit teaching “swing level” and “put the ball on the ground and make them throw you out.” Players do not get scouted and drafted based on their ability to ground out and move runners the hard way; they get to “the next level” by showing that they can hit for, not only average but also for power.”** (Guthrie, 2019)*

Here are key concepts and intentions for optimizing attack and launch angles to *fit the player*:

- There is a tradeoff between more consistent contact and slugging.

- Each hitter’s optimal launch angle for maximum productivity is wholly determined by how hard they hit the ball.

- After Little League, virtually all pitches, including movement pitches, enter the hitting zone between -3 and -21 degrees. By no coincidence, the attack angles of most baseball and fastpitch softball hitters typically fall within this +3 to +21.

- Over 90% of developing hitters fall outside of the typical +3 to +21 attack angle range err on the negative side.

- The average attack angle of MLB hitters is positive (upward) at 9-degrees.

- A fastpitch softball hitter can hit a ball with 63 mph ball exit speed at a 31-degree launch angle, and it just barely clears a four-foot-high 200-foot fence. However, hit the same ball at 63 mph ball exit speed with a 3-degree launch angle, and the ball travels 85 feet in the air and may not get out of the infield.

- There is a correlation between an increase in attack angle and swing and miss rate. In other words, there is a point of diminishing productivity when increasing attack angle, even for hitters with great exit speed.

- If the hitter has a high exit velocity but an attack angle of +5, balls hit above a 25-degree launch angle have a high spin. Contact so far below the centerline loses a lot of potential exit velocity, reducing travel distance. For experienced hitters with above-average exit velocity, a +5 attack angle is an inefficient and unproductive use of the hitter’s power.

- Since, on average, only 5% of batted balls are “barrels” (offset of .5” or less), being a successful hitter is, in large part, determined by how well athletes can optimize their mishits
*.*Purposefully adjusting a hitter’s attack angle to achieve their ideal*average*launch angle improves productivity.

- The ideal attack angle changes over time as the hitter matures and increases ball exit speed.

- Regardless of age, the hitter swings as hard as they can within their mechanics.

### Optimizing Launch Angle for Experience and Type of Hitter

When assessing hitters, learn their bat and ball exit velocity (EV), average attack angle, and average launch angle, and then build a program to bring them into sync with the type of hitter they are or want to be (click for our article **Establish a Hitters Assessment Process**). Finding their optimal swing plane should be on the radar of every hitter high school and above.

The following recommendations for the optimal Attack Angle and Launch Angle are based on typical EV at various ages**.** No need for case studies as it is a matter of physics. Regardless of whether the hitter is MLB or middle school, exit velocity determines how high the hitter can hit the ball and have the best chance of getting a double or better. Prove this out on the field. Ask your hitters to try and hit the ball as far as possible in the air. The slower the EV the less the AA and LA for maximum distance.

__Elementary School Hitters (Baseball and Fastpitch Softball)____ __

The optimum attack angle, as pertains to youth baseball and fastpitch softball, is problematic.

- On the one hand, the highest frequency of contact results when the swing’s upward angle matches the pitched ball’s downward trajectory.

- On the other hand, because the ball is dropping over the plate at -30 degrees or more of a downward angle, a giant uppercut (+30 degrees attack angle) would be required to swing in the plane of the pitch. When bat speeds are lower, extreme upper-cutting produces flyouts. Moreover, striving to swing in-plane with hugely dropping pitches creates the habit of hitching and dipping. These habits can be troublesome to correct later.

Therefore, *Building Rome Series* recommends beginning hitters not worry so much about angles. Instead, concentrate on building sound fundamentals, have the intent to swing hard in games, and go from there.

__Middle School Hitters (Baseball and Fastpitch Softball)__

So, what about the preferred attack angle for our developing hitter? Here is one opinion:

* “If you’re 10 years old and your coach says to get on top of the ball tell them no. Because in the big leagues, these things that they call groundballs are outs. They don’t pay you for groundballs. They pay you for doubles. They pay you for homers.”** (These days in baseball, every batter is trying to find an angle, 2017)*

Are ground balls always unproductive? Not necessarily. The harder the hitter drives the ball (ball exit velocity), the more chance they will get on base no matter their attack angle. But as the hitter advances past 12U and the infielders don’t make as many errors, arms get stronger and more reliable, cover more area, and field conditions improve, negative launch angles are more often gobbled up.

A downward, or for that matter, even a zero-attack angle swing (level to the ground) dramatically reduces the rate of contact (margin of error) when the pitch is consistently arriving at a downward angle of 15 degrees or more. Conversely, an attack angle level to the pitch (+15) leads to a high rate of squared-up contact, but due to the moderate ball exit speeds at this age, these are fly ball outs. So, what attack and launch angles should the developing hitter strive for? A compromise is best:

*For the developing hitter averaging between 40 to 55 mph exit velocity, adjust the attack angle to about +8 degrees and the average launch angle to +13 degrees. The launch angle generated by this attack angle is most productive, leading to line drives landing in the outfield while at the same time constructing a swing path to dominate at higher levels of competition.*

One further note:* Building Rome Series* believes a roadblock to the hitter’s progress occurs when developing hitters try to hit ground balls to get on base. Becoming a ground ball hitter does little for their future. Don’t cut corners for expediency, only to have to reprogram the hitter later. Instead*,* introduce launch angles during the fundamental teaching phase of training. Using launch angle markers in your practice area (click on **Measure Launch Angle in Your Cage**) helps your hitters visualize the eventual goal and begin to adjust their intentions.

__Power Hitters (Baseball and Fastpitch Softball) – High School and Above__

For high school and above power hitters, with an *average* ball exit speed of 75+ mph (baseball) or 65+ mph (softball), the highest home run probability requires swinging with a +15 to +20 attack angle and a 25 to 30-degree launch angle. But there is a penalty for the larger attack angle utilized by homerun-type hitters. When the attack angle is high, the batter is no longer swinging level with the pitch’s trajectory. Because the swing path is more of an upward angle than the ball’s descent angle, when timing or aim is slightly off, a swing and miss, a high fly out, or topped ground ball results – the margin of error is reduced. As a result, the rate of hard-hit balls declines, and strikeouts increase. The high school power hitter must be committed to their homerun strategy.

__Gap Hitters (Baseball and Fastpitch Softball) – High School and Above __

The following objectives **maximize **productivity by increasing the rate of hard-hit balls and extra-base hits:

- Average ball exit speed of 60+ (softball) and 70+ (baseball).
- +10 to +15-degree attack angle.
- 15 to 20-degree launch angle.
- Gap hitting.
- Optimal swing path to each pitch location.

The hitter still hits home runs when their aim is slightly under the ball.

__Contact Hitters (Baseball and Fastpitch Softball) – High School and Above.__

The level to the ball, in-plane swing, is one where the attack angle coincides with the descent angle of the ball (click on our article **Swing in the Plane of the Pitch**).

- The average baseball fastball at high school and above crosses the plate between 7 to 12 degrees of a downward angle. The baseball hitter needs an attack angle of about 10 degrees to most consistently hit a line drive.

- The average fastpitch softball crosses the plate between 4 to 7 degrees of a downward angle at high school and above. Therefore, the fastpitch softball hitter needs an attack angle of about 5 degrees to hit a line drive consistently.

Such a swing is very forgiving of errors in timing. If making solid contact at the highest rate is the primary goal, minimizing strikeouts, then swinging level with the pitch plane is the best strategy. When the hitter “barrels up” the ball, low trajectory singles are the typical result. When their aim is a little off, doubles the fence (contact a bit more towards the bottom of the ball) or hard ground balls (contact a little more towards the top of the ball). Depending on exit velocity, home runs are typically rare. Striking the ball so far below the centerline (large offset), necessary to produce the higher launch angle to carry over the fence, loses a lot of energy during bat-ball contact. For most hitters, a low attack angle and high launch angle usually result in a flyout.

*A contact strategy maximizes hard-hit balls (HHB%) and minimizes strikeouts but does not maximize extra-base hits. For more powerful hitters, a contact strategy does not maximize their potential productivity.*

Hit the ball THROUGH the fence. Low and hard. The homeruns will come.

How did you come up with the optimal EV, AA, and LA for high school hitters? I know we can find all the data on these metrics and see the probability of achieving a hit for MLB hitters (i.e. Baseball Savant’s Statcast Exit Velocity & Launch Angle Breakdown website), but that has to be different for high school. Are there case studies available?

Thanks for your comment.

The optimal AA and LA are based on typical EV at various ages.No need for case studies as it is a matter of physics. Regardless of whether the hitter is MLB or middle school, exit velocity determines how high the hitter can hit the ball and have the best chance of getting a double or better. Prove this out on the field. Ask your hitters to try and hit the ball as far as possible in the air. The slower the EV the less the AA and LA for maximum distance. But again, as I say in my article, getting on the plane with the ball also needs to be considered for maximizing the rate of Hard Hit balls. Youth pitchers throw a slower dropping pitch indicating contact will be more frequent if AA is greater. Hope this all makes sense. Your question is a good one and I would be interested to hear your thoughts.
