Melton exited Triple-A Durham's game against Gwinnett on Saturday due to right hamstring tightness, Marc Topkin of the Tampa Bay Times reports.
The 25-year-old has played in just 36 games for Durham this season, missing time on account of a left ankle issue and now because of a hamstring injury. Melton has produced a .285/.381/.520 slash line with five home runs and 23 steals with Durham.
