Mac Williamson is back with the Giants, if they ever play a baseball game again. His first and only game with the club so far this year saw career numbers for him, with four RBI and a home run. You’ll likely recall Williamson’s hot start to 2018, before his season was tragically derailed by a concussion. That same fate could be avoided for future players, if only the bullpen mounds were moved off the field. And Williamson appeared to be trying to make that a priority from the moment he rejoined the team in Colorado on Tuesday.
