Young missed a month of action earlier this season after slamming into the outfield wall while making a catch in mid-April.
At the time of the injury -- after 11 games -- Young was hitting .410 with five home runs, 13 RBIs and a .500 on-base percentage and seemed to be on his way to one the best seasons of his career.
In 42 games since returning from his injury, Young has hit just .147 with four home runs, seven RBIs and a .252 on-base percentage.
"He's working hard," D-backs manager Kirk Gibson said. "One thing I know about that kid, he's very determined, he works hard, he goes out and he's a pro. He plays his tail off. I think he's just trying to figure some things out and get better results."
Young hasn't had a multi-hit game since June 10 and knocked in three runs the entire month of June.
He hasn't hit above .158 in one month this season since the injury, but Gibson said the club still has not lost faith in their center fielder.
"We know he can do it," Gibson said. "He did it early in the year and since he's come back he's just really struggled against right handers. I think he's trying a few things and making a few adjustments so he can get on it better."
It would be easy for Young to chalk up the offensive struggles to his shoulder.
The injury should give him an excuse and also allow him to take some time to recover.
Gibson said that's just simply not the kind of player Young is. "Honestly, he wouldn't tell me [if his shoulder hurt]," Gibson said. "He's in game mode, he's in play mode. It's really one of the things that's admirable about the guy. He knows it's time to go, he's not going to run from anything regardless of how he feels."
