Major League Baseball recommended teams have protective netting between the dugouts for any field-level seats within 70 feet of home plate.

The guidelines were announced Wednesday at the winter meetings following a season in which several fans were injured by foul balls, prompting MLB to study fan safety. Most teams are expected to expand their use of netting.

"It is important that fans have the option to sit behind protective netting or in other areas of the ballpark where foul balls and bats are less likely to enter," Commissioner Rob Manfred said. "This recommendation attempts to balance the need for an adequate number of seating options with our desire to preserve the interactive pregame and in-game fan experience that often centers around the dugouts, where fans can catch foul balls, see their favorite players up close and, if they are lucky, catch a tossed ball or other souvenir. "

The recommendation also applies to spring training ballparks, many of them owned by municipalities.

Bowl system under scrutiny

Three teams with losing records will be among the 80 playing in a record 40 bowl games over the next month and two teams from the same conference will play each other in a bowl. This offseason, a task force will study the bowl system, intent on making changes to prevent that from happening again.

"The members are going to have to figure out, what's the purpose of bowl games?" NCAA President Mark Emmert said. "Is it a reward for a successful season or is it just another game that we're going to provide an opportunity for?"
