SCOTTSDALE, Ariz. -- Archie Bradley was hitting his spots while warming up in the bullpen, but when the game started, it was a different story.
Bradley allowed four runs on five hits and walked two while striking out one over two innings of work Thursday against the Mariners.
"In the 'pen, I felt good," Bradley said. "I was throwing strikes. I really felt good with where I was at and then at the start of the game just lost it. It's never good when you're throwing 90 percent of your pitches out of the stretch. Just never could find consistency or really get comfortable. Just could never find a good spot and get where I felt good throwing the ball."
It was the first rough outing of the spring for Bradley, ranked by MLB.com as the top pitching prospect in baseball. In two previous starts, he had not allowed a run in 6 1/3 innings.
"He didn't have it," D-backs manager Kirk Gibson said. "Actually a little bit of humble pie today maybe. Struggled with his command. You're going to have those days, and hopefully he'll learn something from it. He should benefit from it."
It sure sounded like Bradley did.
"Any time you're having to work behind in the count is never good, and I just couldn't ever get that first pitch over and it seemed like every batter I was working from behind," Bradley said. "You're not going to have a lot of success when you do that."
Bradley's next outing will come March 21 against Team Australia in Sydney.
With starter Bronson Arroyo's status for Opening Day in doubt, Bradley remains a candidate to start the year in the rotation.
"I know what I need to work on going into my bullpen and now I've got to get ready for Australia," Bradley said.
Trumbo familiar with Sydney Cricket Ground
SCOTTSDALE, Ariz. -- When the D-backs play at the Sydney Cricket Ground next week, it won't be the first time that left fielder Mark Trumbo has visited the stadium.
Trumbo has friends in Australia, and he attended a cricket game there around five years ago.
"I thought it was cool," Trumbo said. "The Cricket Ground was really nice and the energy was awesome."
The stadium has been renovated since then, but Trumbo is confident that one thing has stayed the same.
"The fans, they're very passionate and loud," he said. "Hopefully, we can win a few of them over."
Ross likely won't be active for home opener
SCOTTSDALE, Ariz. -- For the second straight year, it looks like outfielder Cody Ross will not be active for the D-backs' home opener.
Ross is ahead of schedule in his rehab from a fractured and dislocated right hip suffered last August, but the team is not planning on taking him to Australia next week.
That means he will need to be placed on the disabled list and would need to miss at least the first three games of the Giants series March 31-April 2.
March 31 is the D-backs' home opener, which Ross missed last year when he was on the disabled list.
"Definitely on track for March 31, but with the rules being if they put me on the DL, I'll miss the first three days of the season, the home opener, which is a bummer," Ross said. "This is my second one I'm missing in two years, which stinks."
Ross has yet to play in a Cactus League game. His activity has been confined to Minor League games and he is yet to play defense, something he hopes to do next week.
