Worth noting

• Injured D-backs right-hander Daniel Hudson threw a scoreless inning Tuesday night for the D-backs' entry in the Arizona League.

Hudson, who is attempting to come back from two Tommy John surgeries, has allowed just one run in four innings over four appearances in the Arizona League.

The D-backs are hoping to get him some appearances out of the bullpen in September.

"He threw great," Gibson said. "I got a good report on him. His velocity was up last night. He's feeling much more comfortable."

• Chase Anderson, Cliff Pennington, Xavier Paul and Jordan Pacheco visited patients at the Walter Reed National Military Medical Center on Wednesday morning.

• Outfielder A.J. Pollock, who is trying to return from a fractured right hand, is starting to progress again. Pollock suffered a setback when he was hit by a pitch on the hand while in the Arizona League.

"He's getting closer," Gibson said. "I haven't got a first date on when he's going to start playing again. He's close to getting in games again."

• Outfielder Cody Ross (left calf strain) is still not able to run using his full body weight. Ross is currently using an anti-gravity treadmill that allows a person to offload some of their body weight.

"He got set back when he tried to push it, and I don't think he's that close to playing yet," Gibson said. "But he's doing all the activities that he can."
