Okay, I’ll admit it…
The one hitting fault that is a bugger to fix is,
Rear Racing Elbow.
Unfortunately: I find that a baseball hitting instruction fix for one player with this challenge, may not work for another.
Fortunately: I do see symptoms that tend to haunt specific Rear Racing Elbow bat drag hitters.
Unfortunately: I also find that the same combination of symptoms may not be present for every hitter.
Fortunately: For this baseball hitting instruction drill to work, the symptoms must be present.
In this post:
- We’ll define Rear Racing Elbow,
- Look at the symptoms of this particular case study,
- Front knee action at landing: slightly bent or straight? and
- How we fixed the issue in one 30-min session, using RNT…
What is Rear Racing Elbow?
It’s when the rear elbow “races” passed the hands towards the middle of the body (see “BEFORE” image up and to the right).
It can cause the hitter to:
- Dump the barrel prematurely, which leads to flares OR misses completely to the opposite field, OR
- Roll over or get jammed on inside pitches.
It’s a nasty bug to fix with conventional baseball hitting instruction, and one my readers sounded off on at the following two HPL posts:
- Hitting Tips to Boost Barrel Time on Pitch-Plane, and
- Baseball Online: Never Suffer from Bat Drag Again.
Symptoms of Rear Racing Elbow Bat Drag
In this particular baseball hitting instruction case study, one of my local hitters Zack May, a Sophomore in High School, over the past year, has been haunted by these three things…NOT getting the:
- Front leg to straight at or passed impact,
- Back knee to 90-105 degrees during the turn, and
- Downhill shoulder angle before landing.
Front Knee Action at Landing: Slight Bend or Straight?
This is a major baseball hitting instruction debate among instructors I respect. They teach their hitters to keep a slight bend in the front knee at or passed impact.
They point to big sluggers like Mark McGwire (pictured to the right) and Mark Teixeira, among others, as examples.
The amount of bend in the front knee up to impact will depend on the amount of forward momentum (FoMo) the hitter uses.
The more FoMo a hitter uses, the more Ground Reaction Forces (GRF) are needed to transfer planes of motion from the Frontal/Coronal* (sideways) to the Transverse* (twisting). In which case, a straightening of the front knee would be highly recommended. Hitters like Jose Bautista and Josh Donaldson come to mind.
On the contrary though, like a lot of big sluggers, the less forward momentum (wide to little striders), there doesn’t seem to be a need to straighten the front knee during impact.
Think of a wide receiver running a 10-yard 90-degree cut route. He uses GRF and FoMo just like a hitter, but he’s transferring from Sagittal* (front) to the Frontal/Coronal* (sideways) plane of motion. In this case, he’s reaching a maximum forward running speed (FoMo), then has to cut very quickly, so you’ll see his plant leg go from bent to straight as he uses Ground Reaction Forces. Evidenced by him dropping down (or getting shorter) before making the cut.
My hitter Zack is both tall (6’4″), and uses quite a bit FoMo. So, for him, when that front knee doesn’t get to straight, that’s a problem. Coupled with the issue of not getting sufficient bend in his back knee during the turn causes the pelvis to not fully rotate. And as a result, his back shoulder and arm feel like they have to do extra work. And Rear Racing Back elbow is born!

Baseball Hitting Instruction: How We Fixed Zack’s Bat Drag in 30-Mins…
To get you up to speed, check out this Dustin Pedroia & how to fix stepping in the bucket post I did that will explain the use of Reactive Neuromuscular Training, or RNT.
Baseball hitting instruction and RNT drill we used with Zack,
- We used two long resistance bands positioned as close to his pelvis as possible (high up the thigh without damaging “the goods”),
- Both resistance bands pull in opposite directions (feeding the mistakes – front knee wants to stay bent, and back knee wants to straighten during the turn), and
- We worked on getting him to “resist the resistance” during the turn.
One thing we also used that seemed to be the permanent fix was finger pressure (see below…)
Baseball Hitting Instruction SAFETY Issue: Please be careful with this drill. The person facilitating the front band is in the way of a swinging bat!!! To be done with adults who know better, not teammates. Please watch video above for clarification on this.
