Both sides acknowledge the uniqueness of the season would not be limited to stadium location or roster size. Among the possibilities that have been discussed among people from both sides, though not in the talks Monday, according to sources:
• Implementing an electronic strike zone to allow the home-plate umpire to maintain sufficient distance from the catcher and batter
• No mound visits from the catcher or pitching coach
• Seven-inning doubleheaders, which, with an earlier-than-expected start date, could allow baseball to come closer to a full 162-game season
• Regular use of on-field microphones by players, as an added bonus for TV viewers
• Sitting in the empty stands 6 feet apart - the recommended social-distancing space - instead of in a dugout
Each option, though far from certain, is likely to be bandied about in the coming days as the viability of the plan for everyone involved takes shape.
