Continuing a long-standing All-Star Week tradition, Commissioner Rob Manfred answered fan questions, through social media and in person, at a Town Hall meeting during FanFest at Petco Park on Tuesday. The address, hosted by Padres Hall of Fame announcer Dick Enberg, covered a wide range of topics, from possible tweaks to the instant replay review challenge system to how to give the soon-to-be-retired Vin Scully a proper sendoff.
