Challenges not used in the first six innings will not carry over, and a manager who wins a challenge will retain it.
The home run replay rules currently in use will be grandfathered in to the new system, Schuerholz said.
MLB expects to use the new system in the 2014 playoffs, and the system could be enhanced in the postseason. Training sessions for umpires will start in the Arizona Fall League this winter and continue into spring training.
“We know we have to prepare people for this,” Schuerholz said. “Everyone is embracing it. We believe managers will in time.”
Schuerholz said after the first year MLB will look at what worked and what didn’t and make adjustments for 2015. “It’s going to take some time,” he said.
One of Selig’s major concerns was the possible slowing of games. Schuerholz said with a direct line of communication between the central office and the ballparks the expectation is that replays under the new system will take 1 minute, 15 seconds. Current replays average just over 3 minutes.
“We want to prevent stalling,” Schuerholz said. “If it’s a reviewable play, he (the manager) has to tell the umpires he’s going to review it.”
In other matters, Selig said baseball’s investigation of Biogenesis, the now-closed Florida anti-aging clinic accused of distributing banned performance-enhancing drugs, has been completed.
Alex Rodriguez was suspended through 2014 and All-Stars Nelson Cruz, Jhonny Peralta and Everth Cabrera were banned 50 games apiece on Aug. 5 when Major League Baseball disciplined 13 players for their relationship to Biogenesis. Rodriguez has appealed his suspension.
Selig also called the Tampa Bay Rays stadium situation “very, very discouraging.”
“Baseball needs a resolution to this problem,” Selig said with Stuart Sternberg, principal owner of the Rays, in the room listening. “I find it a very, very troubling situation. We were optimistic this was moving in a very positive direction. Unfortunately, it’s stalled.”
