All Major League Baseball teams were wearing Marjory Stoneman Douglas caps on Friday to honor the victims killed at the Parkland, Fla., high school on Feb. 14. Anthony Rizzo, who is not scheduled to play in the Cubs’ Spring Training opener against the Brewers, was wearing it for the workout on Friday. The Cubs will wear the caps again on Saturday for the home opener against the Rangers, and Rizzo will be in the lineup then.
