Jason Heyward bounced back last year after a disappointing 2011 campaign. He added more muscle to his frame this offseason, bring the 6-foot-5 hitter to 235 pounds.
Heyward's stats through his first three seasons include a .261 batting average with 59 homers, a .352 on-base percentage and a .447 slugging percentage.
"Jason can be probably one of the greatest players in the league," Hank Aaron said. "He runs the bases well. He can steal bases. He plays the outfield about as well as anybody in right field. He's got a great arm, and he plays well. You like to see a player like that, because he doesn't play like he's going to get hurt. He plays reckless, and he runs the bases very well."
