What happened: Bryce Harper proposed allowing hitters to swing aluminum bats during the Home Run Derby when gold balls are in play, per @Buster_ESPN. The suggestion comes ahead of the upcoming event at Citizens Bank Park.

Why it matters: The equipment change would drastically increase exit velocities and distance, potentially sending balls entirely out of the stadium. Harper recently committed to the event, driving significant interest in the Philadelphia showcase.

What to watch: Major League Baseball has not indicated whether it will consider the equipment adjustment for the bonus round. The All-Star festivities begin next week.
