In a huge and wide-ranging rules change for high school baseball, the National Federation of State High School Associations – which makes rules for sports nationwide – has adopted the use of a double first base, which adds an extra base of the same size in foul territory, in an effort to cut down on injuries, and avoid interference calls.
The additional base is often used in lower levels of the sport, such as little league, but now will be mandated nationwide starting in the 2027 season, including here in New Jersey.
The NJSIAA has allowed it in recent years, but at the option of each school. Starting in 2027, it will no longer be an option, unlike other “permissive” rules, such as the shot clock in high school basketball. NFHS allows it to be used, but states have the option, and New Jersey – so far – does not.
But it will have to add the extra base.
First base is positioned from the outer edge of the foul line into fair territory, but is only 18 inches across. The additional base would be connected to the existing base and be entirely in foul territory. As always, a ground ball that hits or crosses the main base – which will remain white – is considered fair. Anything that hits or crosses the secondary base – which is to be a different color, most often orange – is considered foul, as the base sits entirely in foul territory.
Additionally, on a play at first, the fielder is permitted to step on the white portion of first base only, and the batter-runner is allowed to step only on the colored portion of the base. A fielder stepping on the secondary base will be ruled obstruction, and the batter-runner will be ruled safe. Likewise, a batter-runner stepping on the white part of the base will be called out on interference.
In the case where there is not a play at first – such as a walk, or making the turn on an extra base hit to the outfield, though not a single because a force play is still a possibility – the batter-runner can use either part of the base.
Once a batter-runner is safely on base, only the white part of the base can be used. For example, on a pickoff play from the pitcher, if the runner is only touching the orange part of the base and is tagged, the runner would be out. The same would apply for tagging up on a foul ball.
Another NFHS rule change addresses player defensive meetings, considering them as “charged conferences.” Each team will be limited to no more than one player-to-player meeting during an inning. A meeting is defined as two ore more defensive players.
