Definitely going with PG on this one.
Trying to "deflect" a scorching ground with the glove palm can be problematic.
For the standard grounder:
- Good footwork on the approach, keep the feet moving in small steps.
- Always move toward the ball, even if it is a screamer where you only have time for a half step. This puts you in the right physical and mental attitude.
- Bend the knees & get low, the backside should be down (not sticking up in the air). Getting low will help judge the hop better.
- Staying low will also make sure the glove is out in front of the body. This is critical to maintain good, full vision of the ball all the way into the glove with both eyes.
- Start low with the glove & come up if necessary. You can bring the glove up much quicker than you can move it down.
- Get the throwing hand touching the glove as the ball approaches the glove. Some use the "gator grip" (as I taught), others use "pinkie to pinkie". If the hand is not next to the glove, time is wasted getting the throwing hand to the glove for the transfer.
- Bring the glove up while the throwing hand is getting the grip. Some folks want the transfer completed while the glove is still down, but that isn't necessary and gives lesss time to get a decent grip. [This can be done even in the "deflection style".]
- Stay low and get a good right foot plant from which to make a strong throw.
When it comes to backhands, running scoops, diving, etc. then different techniques are required of course.
Just a few thoughts, I'm sure others could do better.
On turning the pivot and receiving DP feeds, I tended to do more "deflection", but the throwing hand was touching the glove. And I must admit I never took time to get a four seam grip when turning the pivot. The throws were accurate enough and I didn't want even a split second spent that wasn't absolutely necessary. For the second bagger, staying low and having a strong right foot plant are critical.
And anyone putting on someone else's glove should be grounds for justifiable homicide.
