Introduction to Swing on Plane

In this article, we describe how to get on plane with the baseball or softball. The ability to swing the bat at the same level as the trajectory of the incoming pitch improves ball exit velocity (click for how to measure EV) and the frequency of hard-hit balls:

Here are two concepts:

But, there is a drawback to swinging the bat on the same level as the ball:

While swinging on the same plane as the pitch crosses the plate increases the percentage of hard-hit balls, it is important to understand that this skill does not necessarily optimize the hitter’s productivity.

For many hitters, swinging slightly more up than the level of the incoming pitch increases the distance of the hit ball resulting in a higher frequency of doubles, triples, and home runs.

Who Should Swing on Plane?

The Attack Angle required to swing precisely in the pitch plane produces Launch Angles with lower trajectories than ideal for most older and stronger hitters.

Swinging on plane is not optimized for extra-base hits.

Swinging on plane may be a productive strategy for:

 

The History of Swinging Up

 

(Williams T. , Science of Hitting, 1970)

The optimum swing plane for hard-hit balls has not been a hidden secret, which we are just now discovering (thanks to the advent of bat sensors and swing analyzers). For example, Ted Williams (the last Major League Baseball player to bat over .400 for a season) in his historical book, “The Science of Hitting,” published in 1970, advocated swinging with a slight uppercut to match the trajectory of the incoming pitch (image above). This idea was in stark contrast to the prevailing wisdom (hands short and linearly A to B to the ball) of the day.

 

Swing on Plane Defined

The baseball and softball hitter swings the bat in the same plane as the ball travels to maximize the number of hard-hit balls. The barrel moves on a slightly upward angle (baseball 7 to 12 degrees; fastpitch 4 to 7 degrees), exactly coinciding with the fastball’s downward trajectory as it reaches the plate. The hitter must avoid dipping under the ball or upper-cutting too much.

“Getting on plane with the pitch is not to drop the barrel below hands too much or too early and then follow thru high — it is not that.” (Williams T. , Science of Hitting, 1970)

The hitter begins by accelerating the barrel on a downward path behind the rear shoulder. The direction of the bat then bottoms out and arcs a few degrees upward to contact. The shape of the swing path is in the form of the Nike logo.

“This is one of the many faulty idioms taught by hitting coaches, that you must swing down on the ball either to create backspin and loft or to hit more groundballs, depending on whom you talk to and what their philosophy is. In fact, the hands do come down, but they do more so behind the body, only to come slightly up as they approach contact. This makes sense if you think about it; the ball is coming in at a slight downward angle from the pitcher’s mound.  This is partially due to release height, but more importantly, because of gravity.  Gravity makes everything fall, and baseballs are no exception.” (Farnsworth, Breaking Down the Swing: Best Hitters of 2012, 2013)

 

Timing of Swinging on Plane

To swing on plane requires the barrel to travel a longer distance with a longer “loop.” However, a longer in distance swing isn’t always necessarily bad. The batter simply syncs movements a little earlier in the pitcher’s motions or ball travel.

Furthermore, while the swing is longer in distance, the hands connect to core and shoulder rotation much earlier. As a result, the barrel moves faster earlier in the swing as compared to a short to the ball linear (hands to ball) hand path. Both power and overall quickness to the ball are improved. The time for the barrel to travel from launch position to contact is reduced (see our free article Time to Contact Measures Quickness).

 

Benefits of Swing on Plane

The baseball and fastpitch softball hitter promotes two productive outcomes by adjusting the swing plane to be on the same plane as the downward angle of the pitch:

Maximizing the size of the hitter’s contact area increases productivity because timing does not have to be perfect.

The expanded contact area serves to improve overall timing. For example, with a larger margin of error, the hitter can be slightly late, making solid contact towards the front knee. Or, if the hitter is somewhat early, solid contact occurs out in front of the front foot. Thus, timing improves even though the upswing is a little longer (in distance) than a short to the ball, linear hand path.

Swinging in the plane of the pitch maximizes ball exit speed.

The barrel and the ball must be traveling in precisely the same plane for one hundred percent of the energy generated in the swing to transfer to the ball. If the swing path and ball trajectory are traveling at slightly different angles at contact, the center of masses (of the barrel and the ball) never wholly align.

“Up, up is the way; you hit consistently with authority.” (Williams T. , Science of Hitting, 1970)

 At High School and above, the baseball or softball pitch’s downward trajectory is 3 to 12-degrees. The hitter utilizes a +3 to +12 (upward) Attack Angle to maximize ball exit speed, precisely matching the pitch’s downward trajectory. These attack angles result in launch angles too low for sluggers with excellent exit velocity to maximize ball travel distance and productivity.

The average trajectory (Launch Angle) of swing on plane hitters is a low liner.

 

Two Crucial Positions Necessary to Swing on Plane

Swinging on plane with the pitch to increase the margin of error and ball exit speed is a matter of achieving a slight upward angle of the swing plane (click the link for our free article Attack Angle (Swing Plane) for Hitters). The positive attack angle matches the downward slope of the pitched ball as it enters the hitting zone.

 

 

To swing on plane, the hitter’s spine angle and axis of rotation are crucial:

 

An inward angle of the rotating shoulders, created by a twenty to thirty-degree spine angle as the hitter turns, has the following effects:

• Contributes to raising attack angle by increasing the vertical bat angle.

• Increases margin of error because the swing path is deeper and, therefore, in the course of the ball longer than with a more upright hitting position.

• Increases power as the hitter is in a more leveraged (torqueing) athletic position.

(Nyman, n.d.)

 

The hitter’s axis of rotation is the primary establisher of the upward gradient of the swing path. The larger the degree of rearward tilt, the higher the average launch angle generated by solid contact.

The hitter can “stay back” (click on our free article Hitting Drills to Fix Lunging) a little more to accurately align the swing plane with pitch trajectory, thereby increasing the margin of error.

Homerun Hitter (swing plane does not match the plane of pitch) (Zepp Analyzer).

Home run hitters often use a large rearward tilt to hit higher trajectory line drives (25-35 degrees launch angle). One downside to this strategy is the reduced margin of error, especially for high pitches, due to the overly upward swing path, which no longer matches the pitched ball (look closely at the image above).

 

Further Swing on Plane Mechanics

Here is a more “granular” list of the mechanics for swinging in the plane of the pitch. Observe these finely honed movements in the slow-motion videos of High-Level hitters:

• The rear shoulder tilting.
• The rear elbow slotting.
• The lead arm is working up.

Swing on Plane Summary

To maximize the rate of hard-hit balls (HHB%), hitters can intentionally match the plane of their swing to the plane of the pitch.
