"Going back for the ball, I knew I had a bead on it. So when I went up to jump, I jumped too early. I came down and I didn't think I was going to hit, then it hit my shoulder," Young said. "It got tight on me, so they took X-rays, luckily nothing is broken with that. I just have to get an MRI tomorrow."
Young's injury could not have come at a more inopportune time for the D-backs. Including a double in the first inning on Tuesday, the team's hottest hitter is batting .410 on the season with five home runs and 13 RBIs.
What's more, D-backs right fielder Justin Upton is also listed as day to day with a bone bruise in his jammed left thumb, and it's uncertain when he will return to the field. The D-backs will also be without Geoff Blum, who was placed on the disabled list after pulling a side muscle during batting practice Tuesday afternoon, D-backs manager Kirk Gibson announced after the game.
The club will promote A.J. Pollack from Triple-A Reno to add depth in the outfield, the manager said.
"Frustration level is real high, it's just bad timing," Young said. "Especially with guys down, you want to be out there to help the team and do what you can. I'm a positive thinker, so I'll pray on it tonight and hope it feels better."
Young initially feared he had broken his collarbone.
"I knew it wasn't a homer, and if it's not a homer, I'm going to try to make the catch," he said. "I've made plays like that in the past, and I've been able to time my jump better to brace myself more, but I hit the crack in the wall."
