Unlucky

From MLB Power Pros Wiki

Manages to lose lots of games somehow

The red pitching ability, Unlucky, is the opposite of Lucky.

When a pitcher with this ability is pitching, his lineup will get reductions to hitting stats. Additionally, when an Unlucky pitcher leaves the game in line for the win, the opponent's lineup will get boosts to their hitting.

These effects may result in poor run support and blown leads from the bullpen, two characteristics of an unlucky pitcher.
