Duno (hamstring) has gone 5-for-14 with two doubles, two walks and a run scored in four games for Double-A Chattanooga since being reinstated from the 7-day injured list Tuesday.
Duno missed about a month of action due to a hamstring injury. The 20-year-old catching prospect continued to produce at a well above league-average level since moving up to the Southern League in late June, slashing .318/.420/.506 with three home runs and one stolen base through his first 23 games with Chattanooga.
