J.D. Martinez and the art and science of the swing

J.D. Martinez and the art and science of the swing By Alex Speier, Globe Staff May 24, 2018 The Red Sox slugger’s swing has been likened to a samurai sword and a Ferris wheel, and it gives him incredible power. Here’s how he does it.  It isn’t supposed to work this way. Players aren’t supposed to hit with power the way Red Sox slugger J.D. Martinez does. There are other players who hit opposite-field homers. But no one does it with the frequency, and on the types of pitches, that Martinez does.

The manager and pitching coach were both just 27 years old; the hitting coach was only three years their senior.

The Physics of the Home Run Boom

The Physics of the Home Run Boom by David Kagan April 6, 2018   Increased exit velocity could partially explain the home run boom, and no one had a higher exit velo in 2017 than Aaron Judge. (via Keith Allison) Whoa! Don’t think for even one short nanosecond this article will definitively explain the cause of the current increase in home runs in MLB.

From a scientific point of view, there are only two interactions that result in a home run. The first is the ball-bat collision, and the second is the flight of the ball. The ball-bat collision depends upon the properties...
