Zones, halves, years and barrels: a clustering recap

Groundballers are aces too!

Zack Greinke 2019 pre-ASG BIP, cluster related averages
  • 2 are no doubters;
  • 3 are common grounders;
  • 4 is tricky, balls hit almost square but not going out of the infield, I called them choppers;
  • 5 are those sly bloops;
  • 6 go to the warning tracks;
  • 7 are hard liners;
  • 8 obviously slow rollers;
  • 9 just got unders.

  • 2 are slow rollers;
  • 3 is the barrel zone;
  • 4 are no doubters;
  • 5 are hard liners;
  • 6 are got unders;
  • 7 is a new finding, longer than bloops, underswung but not popped, these are my short flies;
  • 8 are indeed bloops;
  • 9 finally grounders.
