Arizona Diamondbacks center fielder Adam Eaton will miss the next six to eight weeks with a left elbow UCL sprain, according to the team.
Expected to be the team's leadoff hitter, Eaton was hitting the ball really well this spring with his .390 average over 20 games.
"You know that I will work my butt off to get back in there," he tweeted. "It will be sooner than later."
Eaton is No. 73 on Baseball America's list of top 100 prospects and was No. 1 on Keith Law's list of Top 20 Impact Prospects for 2013.
