So, let’s look at some of the similarities between Jason Heyward and Giancarlo Stanton. 1. They were born three months apart — Heyward was born in August of 1989, Stanton in November that same year. 2. They are football-sized young men — Heyward is 6-foot-5, 245 and Stanton is 6-foot-6, 240. Stanton played football in high school (he was considered a major college prospect) but Heyward was all baseball, all-the time from the time he was 11.
