What the runner-on-second rule does

Many summer leagues place a runner on second to start each extra inning. The rule shortens games and heightens the tension immediately.

With a runner automatically in scoring position, situational hitting carries new weight. A productive out advances the runner toward home.

Staffs reshape their pitching plans around the rule. One inning often will decide the game.

In summer ball, managing the staff weighs, so faster extra innings help overworked arms. The rule balances drama against wear.

As the summer wears on, teams that master the format steal extra-inning games. Adapting to the rule rewards prepared managers.
