There is a hollow directly below (which means beneath) the patella. Everyone has one. It is the visible indentation which I have used to determine the low end of the zone ever since they rewrote the rule. There is no hollow behind the knee.

I majored in Physical Education, which is very similar to pre-med in its classroom studies, with Anatomy, Physiology, and Kinesiology and never once heard of there being a "hollow" on the anterior of the knee. The patellar ligament is directly below the patella, and behind that is the meniscus, which is the hollow of the knee. Behind the leg there is no knee, just a fibrous capsule which separates the femur and tibia.

When the doctor scrapes the area beneath your knee cap, does he scrape below it?

The old image of the strike zone at ML used to have the low point line extend right to the backside of the knee. Now, I believe it points to the knee.

I'll take pro school instructors and ML interps, Steve.

This really isn't worth the BW. Call what you'd like, I merely answered a question with correct, albeit, inconsequential information.

No. And I am not a meteorologist, either. :)

Have you ever stayed at a Holiday Inn Express ? :D

The centerline of the knee cap is just that. The hollow of the knee is the point at which the knee cap ends (toward the foot). It is not hollow, it is filled with the tendon that connects the knee cap to the lower leg bone.

And this centerline moves, so does the zone, up and down as the knee cap moves up and down as you bend your knee.

Several morons, er less intellectually enhanced umpires, use this variation in the lower part of the strike zone to make their case that your original position as you get in the box is the zone they call. :rolleyes: See standing figure in OBR.

The hollow is the indentation that is left/right of the ligament that connects the patella with the tibia. If you use this hollow, then you have Superman X-Ray vision. It is almost always covered by the pants. :eek:

The "knee" is a joint (no not like smoking tumbleweed ;)); anterior and transverse to the joint is the hollow created as described above.

Bzzzzzzzzzzzt. The patella (knee pad) slides over the knee joint. The meniscus is inside the joint...

Note it is not hollow there. The meniscus (cartilage) is inside the knee joint. The hollow occurs right/left and is created by the patellar ligament.

What? The leg where? The leg includes the knee joint. :eek: :confused:

My God, Steve, what would have ever happened in phys ed class, if you had a pateller dislocation?

"Get up, you wimp, there is no leg behind your knee so that thing that is horribly deformed and looks like a small plate over on your thigh ain't anything.";)

The verbiage is the hollow of the knee. It's crap. It was about "at the knee" so MLB moons without being anatomically correct, whilst swiggin brewskis no doubt, came up with this trash.

For me, if the ball, with pants on and Super X-ray vision "Off", the top of the ball, is at the bend of the knee which I can see protruding outside the pant when B flexes, I got a strike.

Other than that, at close strikes have a hell of a lot more to do with the quality of F1/F2 play. And B play.
