CHICAGO -- He won his fourth Gold Glove Award and his inspirational message to his Cubs teammates during the rain delay in Game 7 appeared to spark a rally and an eventual World Series championship. But Jason Heyward wasn't pleased with his .230 batting average in his first season with the Cubs, and the right fielder is now working in Arizona on some changes.
One of the Cubs' mental skills coaches, Darnell McDonald, posted a video on his Instagram account late Monday of Heyward hitting in a batting cage at the team's Spring Training complex in Mesa, Ariz.
