We’ve reached a few meaningful points in the season even though it’s only mid-April. For instance, plate discipline metrics are somewhat reliable now. And even more tantalizing, so too is exit velocity. It takes about 50 plate appearances for exit velocity to be more attributable to the player and not just randomness.
Here are the early season improvers in exit velocity for Cubs batters:
| Player | 2017 EV | 2018 EV | Difference |
| Willson Contreras | 86. |
