Message: [QUOTE="JMick, post: 5344611, member: 6467"] All sweepers are sliders but not all sliders are sweepers. The slider I threw in HS would now be called a sweeper. It's just a seam shifted slider. People have been throwing it forever. We just have analytical data now that shows it's a better grip. Before, people just threw what was comfortable. Now they're actively working on the seam shifted grips, even if it's not comfortable at first, because the analytics show it's a better pitch. It wasn't specified as its own pitch before because the only way to tell the difference is either knowing the grip that the pitcher uses, or today, using the highly precise cameras to track the spin of the pitch.
