SCOTTSDALE, Ariz.-- Missouri All-American defensive lineman Michael Sam's decision to reveal Sunday that he is gay has spurred a discussion throughout the sporting world.

D-backs pitcher Brandon McCarthy offered Sam his support on Twitter on Sunday night and reiterated it through the media Monday.

"I think it's a good thing," McCarthy said. "I don't know if it's a cascading effect, but I'm hoping more people are getting more comfortable with it. I think the ultimate hope is that everyone gets to be themselves.

"It's hard enough to play professional sports and do this when you feel comfortable and I can't imagine how difficult it is if you feel like you can't be yourself and be the person you want to be. I'm just glad from his side he just gets to be the person he wants to be and hopefully now is just judged as a football player instead of everything else."

D-backs manager Kirk Gibson said he thinks his team would be supportive if one of its players made a similar revelation.

"I don't think it would be an issue in our locker room at all," Gibson said.

Top D-backs prospect Bradley applauds Arroyo signing

Top Prospects: Archie Bradley, RHP, D-backs

SCOTTSDALE, Ariz. -- You might think that top prospect Archie Bradley was disappointed when he heard the D-backs signed free-agent pitcher Bronson Arroyo.

After all, that seems to ensure Bradley will begin the 2014 season in the Minors rather than as the club's No. 5 starter.

Bradley, however, took the news in stride.

"I knew it was coming, kind of," he said. "There was talk about us signing a pitcher the whole time, but honestly as cliché as it sounds it really didn't bother me that much. I think if you look at what Bronson brings to this club he makes us better."

D-backs general manager Kevin Towers said Sunday that despite the fact that it looks as if the Opening Day rotation will include Patrick Corbin, Arroyo, Trevor Cahill, Brandon McCarthy and Wade Miley, it is not accurate to rule out Bradley from working his way in.

"It's a long spring and there's a lot that can happen," Bradley said. "But I'm young and I have a lot of time left in front of me and I'm just going to keep preparing, keep learning and just kind of prepare myself for whether it's day one or down the road and they call me and say, 'Let's go.'

"I've said all along my goal wasn't to win a spot, it was to come in and compete and put pressure on this organization to kind of show them the strides I've made and where I've improved and it's still the same thing."

Snake bites

Outlook: Goldschmidt should post solid average

• An errant pitch during Adam Russell's bullpen session hit a D-backs fan, who was watching from an elevated vantage point well behind the plate Monday.

Russell was in the middle of his windup when an errant throw from another pitcher crossed in front of his catcher. Russell, a non-roster invitee to Spring Training, tried to stop his delivery and the ball sailed and hit the fan in the shoulder.

The incident caught everyone off guard as the fan was standing about 20 feet above where the pitchers were throwing and three mounds down from Russell.

"I was just trying to cut it off and hold it and it just sailed on me," Russell said. "I'm sure he felt like he was safe 30 feet up and 30 feet over. I'm glad to see that he got up under his own power and is OK, but my sincerest apologies to that fan."

• D-backs pitchers will take a break from throwing bullpen sessions Tuesday in anticipation of the first full-squad workout Wednesday.

On Wednesday the pitchers will face the hitters in live batting practice sessions.

• Gibson said he is not at all concerned that first baseman Paul Goldschmidt will be complacent after his MVP-type season in 2013.

"He's prepared and he's stayed extremely humble," Gibson said. "I don't think anything is going to go to anybody's head. As good as you think Goldy was, in his mind he thinks he could be so much better and he thinks his teammates could be so much better and we agree."
