But the biggest changes that are one the way are how extra innings will be played.

MiLB laid out a plan to speed up the game by limiting the amount of mound visits and the use of a 15-second pitch clock with no runners on base. The change that stands out the most is that teams will start extra innings with a runner on second base.

"We believe these changes to extra innings will enhance the fans' enjoyment of the game and will become something that the fans will look forward to on nights where the game is tied late in the contest," MiLB president Pat O'Conner said in a statement.

The new rules are intended to shorten the length of the games with by limiting mound visits and the length an extra innings contest may go while keeping in mind player safety and providing more action for viewers. MiLB is also hoping that it will eliminate shortages of pitchers after extra-inning games and the need to shuffle players between minor-league levels.

The extra-inning rule is not new to baseball, just to MiLB. The rule has been used internationally for years. The runner that will be placed at second will be the final out from the previous inning and should that runner score, pitchers will not be charged with an earned run.

In addition, the limits on mound visits are an adaptation of MLB's new policy of six per game that was implemented last month for this season. Triple-A teams will follow the MLB rule. However, Double-A teams will be allowed eight visits while Single-A teams will be allowed 10. Short Season and Rookie-level teams will not be limited.

Another initiative to speed the game comes with changes to the pitch clock rules. In Triple-A and Double-A, pitchers will have 15 seconds to begin their windup when there are no runners are on base. The pitch clock will return to 20 seconds when runners are on the base.

The new rules will go into effect beginning April 20. There will be a grace period from April 5-19 when players will receive warnings for violations.
