Rob Manfred says shortening the regular season is becoming a popular topic as players and owners prepare to negotiate a new labor deal.

The commissioner spoke with reporters in Houston on Wednesday night about several issues, including Pete Rose, pace of play, domestic violence, black players in baseball and the designated hitter.

Manfred said reducing the number of games in a season would have economic and competitive ramifications, but the idea of giving players more off days is receiving more attention than ever.

"One hundred and sixty-two games in 183 days, and a lot of those 21 days consumed by travel, is a pretty demanding schedule," he said. "By reputation I work pretty hard, and I don't think I work 162 days out of 183. It's a tough schedule."
