Sale's head is swimming around his center of mass throughout the delivery,
and though he finishes with strong posture, the journey into release point is
a rough ride. It begins with a slouched position and continues with a steep
drop-and-drive as Sale lowers the center of gravity after maximum lift. The
head drifts behind the body and toward the first-base side as he enters foot
strike, before the spine snaps back into place in time for release point. The
30-grade balance upsets the left-hander's mechanical repetition, but he often
benefits from late swings on misplaced pitches thanks to a deep release
point, as demonstrated in the above GIF. Sale might be running from the
injury police, but a lack of balance is the biggest threat to his performance
on the field.
意思是说Sale常常可以靠失投球骗打者吗@@?
