Fowler pinch-hit in the ninth inning of Sunday's 5-4 loss to the D-backs, drawing a one-out walk before being stranded at third base with two outs representing the tying run.
After Fowler was hit with a Trevor Cahill pitch in the third inning Saturday night, trainer Keith Dugger brought Fowler into his office and said he took seven images of Fowler's hand and wrist with a fluoroscope that Dugger had just received Saturday.
"It's on trial right now, but it was perfect," Dugger said of the device.
Fowler stayed in the game and finished 0-for-3. He has one hit in his past 15 at-bats, but Weiss said what Fowler has done lately at the plate was not the reason he wasn't in the lineup.
"He's had some quick at-bats, and they're mounting up a little bit," Weiss said. "But I'm not too concerned about that. Dexter's been swinging the bat really well. I'm more concerned about the physical thing."
