With the Toronto Blue Jays announcing that they will be adding protective netting down foul lines on Monday, 25 of 30 MLB teams have expanded their safety precautions to protect fans from rogue foul balls. Only the Chicago White Sox, Los Angeles Angels, Oakland Athletics, Baltimore Orioles and Miami Marlins remain among teams that have not yet expanded their netting.

The issue was cast into the public eye after a scary incident in which a young girl was carried out of Yankee Stadium after Todd Frazier laced a ball foul against the Twins. Play stopped as she was tended to, and a spirited debate began about expanding netting.

Many of the concerns against netting are based on fan experiences. Netting inhibits fans reaching for foul balls, and some argued that it would impair vision. In spite of these concerns, slews of teams at a time have been announcing that they will be expanding the nets.
