PHOENIX -- Daniel Hudson threw a bullpen session Friday and remains on target to start Sunday against the Brewers.

The D-backs right-hander has been on the disabled list with a right shoulder impingement since April 19.

Hudson, who got a cortisone injection after the injury, has not experienced any setbacks since. He threw in extended spring camp before making one rehab appearance for Triple-A Reno.

"After I got the injections and the inflammation went down, I never felt it again and I haven't felt it since," Hudson said. "I've never had anything like this happen before, so I was pretty nervous the first time I picked up a ball for the first time afterwards."

Hudson will join the D-backs on their road trip to San Francisco and San Diego after Sunday's game. It will be the first time he's been on the road since the injury.

"Not being able to be on the road with the guys and having to watch the games on TV, it's been frustrating for me," Hudson said. "Just being able to get back in the swing of things, pitch and then put the suit on and go on the road with the guys will be just a big relief for me."

D-backs taking cautious route with Montero

PHOENIX -- Miguel Montero was itching to get back in the lineup on Friday, but the D-backs' catcher understood that the team wanted to be cautious with his injured groin.

Montero, who tweaked his groin in Monday's game against the Dodgers, was kept out of the lineup Tuesday and Wednesday.

"He's not ready to play yet," Arizona manager Kirk Gibson said Friday. "He's not ready to go catch a game right now at this point. He's got more range of motion, it feels much better. We put him through a lot of baseball activities and movements today, so we'll see how he reacts. He's not a fast guy, but he runs very hard."

Is it realistic to think he could play at some point this weekend against the Brewers?

"Yes, it's possible," Gibson said. "Tomorrow's possible, but I'm not sure yet. We'll see."

The D-backs added backup catcher Konrad Schmidt from Triple-A Reno earlier this week, and they will have him until Sunday when they will need to clear a roster spot for right-hander Daniel Hudson, who is set to come off the disabled list.

"If you throw me out there right now I'll play," Montero said. "If they ask me how I feel, I say great, but I understand the point [that] there's no reason to force it today when we can easily give it another day or two."

Worth noting

• Third baseman Josh Bell was out for some early work with infield coach Matt Williams on Friday. Williams won four Gold Gloves during his 17-year playing career.

"Footwork is everything," D-backs manager Kirk Gibson said when asked what Bell was working on. "Just trying to clean some things up. He's a big guy, so footwork is essential. Just trying to teach little angles, how to approach the ball, how to set yourself up for the throw a little better."

• Gibson said the fact that the D-backs trail the Dodgers by 10 1/2 games in the National League West should not be a focus right now.

"You can't let it affect the way you play," Gibson said. "Look what the Cardinals did last year. They came from way back, way late, so it is possible. And there is another way to get to the playoffs this year [via the extra Wild Card]."

• Second baseman Aaron Hill was out of the lineup on Friday. Gibson said Hill has been bothered by a nagging knee injury.

"I thought I would just give him an extra day," Gibson said. "I know he's not too happy about it."
