Injuries have been a bit of a problem for Hamilton so far in his career as he was limited to fewer than 120 games in each of the last two seasons.
When healthy, however, the center fielder is a game-changing player thanks to his speed. He totaled 171 stolen bases over his first three full seasons, also using his athleticism to excel defensively in the outfield.
He has kept it up in 2017 with 58 stolen bases to lead the majors.
Hamilton has struggled to maintain high batting averages and on-base percentages throughout his career, though, especially for a leadoff hitter, posting just a .299 on-base percentage in 2017.
The recent injury only raises more problems for the young player.
Considering the outfielder remains under team control for another two years and the Reds are out of the playoff race, the team might choose to be conservative with Hamilton's recovery from the latest injury.
