Major League Baseball and the players association announced their agreement on several rule changes Thursday, including pitchless intentional walks. All of the changes listed below took effect with Thursday’s exhibition games. Here’s a look:
— Video review regulations were changed to establish a 30-second limit for a manager to make a challenge and a conditional two-minute guideline for the replay umpire to make a decision. When a manager is out of challenges, an umpire crew chief may ask for a review of a non-home run call starting in the eighth inning, one inning later than last season.
— An addition to rule 5.07 likely will come to be known as the Carter Capps rule. The Padres reliever is known primarily for his funky, hopping delivery. The rule now prohibits a pitcher from resetting his pivot foot or taking a second step toward home plate during his delivery. If the pitcher violates the rule with a runner on base, a balk should be called. If there are no runners, a violation should be considered an illegal pitch under rule 6.02(b).
—  A change to rule 5.03 requires base coaches to remain behind the line of the coach’s box closest to the plate and the front line parallel to the foul line before each pitch. A coach may leave the box to signal a player after a ball is put in play as long as he does not interfere with play.
—  MLB also announced the prohibition of field markers to create references for positioning fielders.
