Tough Runner

From MLB Power Pros Wiki

The blue ability, Tough Runner, the player will run around the bases with more gusto and quickness. It is speculated that paired with a fast speed and Aggressive RUN, the addition of this ability can turn a close double into one standing up. Tough Runner actually just allows the runner to barrel over the catcher in a close play at home. The ball is occasionally knocked out of the catcher's mitt.
