Rob Manfred isn't in favor of playing the World Series under a single set of rules in future seasons.
The Cleveland Indians played Carlos Santana, their usual designated hitter, in left field at Wrigley Field on Friday night.
"I think the problem is picking what that one set of rules is," Manfred said.
"The National League plays without a DH all year. Their team is built to play without a DH. It's the opposite in the American League. And I think the competitive ramifications of picking a single set of rules would be significant.
"Both teams have to adjust. Each of them has to adjust at some point in the series. And given that we play the game two different ways during the year, that makes some sense to me."
