SAN FRANCISCO -- The D-backs plan to stick with their current roster composition -- 13 pitchers and 12 position players -- for now, but you can expect that to change when outfielder Cody Ross returns from the 15-day disabled list.
"We'll have to revisit when and if he's ready," D-backs manager Kirk Gibson said Tuesday.
The decision to carry 13 pitchers proved to be a good one because the starters struggled to pitch deep into games during the season's first full week.
"It worked to our advantage because we needed them," Gibson said. "Does it influence what I do during the game with my position players? Absolutely. I mean if you get into extra innings, it really influences you. So you're maybe a little more mindful of what you want to do earlier in certain situations where if you had the extra guy it would change."
Ross played six innings for Triple-A Reno on Monday and legged out an infield hit and made on over-the-shoulder catch in left field.
"He's doing good," Gibson said. "He's running and moving much better. Much better. He's made vast improvements since he's been down there starting to play. He played left last night. I texted him last night and told him to make sure he moves around."
The team plans to use Ross either in left or right field when he returns, but if he's moving around well enough, over time he could see action in center, too.
D-backs being careful with Reed's workload
SAN FRANCISCO -- One of the trickiest things for a manager is balancing keeping his closer fresh with making sure he gets consistent work.
D-backs closer Addison Reed pitched in a save situation Sunday against the Rockies, but regardless of what the score was, Reed was going to pitch an inning because it had been four days since he last had pitched.
"It's tough to gauge," Reed said of the balancing act. "Like Sunday I think I had four days off and I don't ever really like to go past four. Say it's been three days, I'm definitely going to throw a side."
That's what Reed did Saturday, throwing a touch-and-feel light side session during the game, just enough to give him the feel of pitching without tiring him out in case he's needed.
"You just see how he's feeling, where you're at in the season, how hard his last outing was, or his last three outings were," D-backs manager Kirk Gibson said of determining Reed's workload. "We used him two days in a row and we thought probably because it was so early in the season that we'd only go two days. You have to be proactive in trying to avoid that, sometimes even early on. Now, I mean, they feel strong, but I think the consensus is that it does take something out of you when you do extend them right now. That goes for all the players."
Reed appeared in six games over a seven-day stretch for the White Sox last season, but don't look for Gibson to use him like that.
Trumbo flashing plenty of power for D-backs
SAN FRANCISCO -- D-backs left fielder Mark Trumbo is off to a hot start with five homers and 13 RBIs through the first nine games of the season.
"He's played well for us," D-backs manager Kirk Gibson said. "He's a very formidable bat and a smart hitter."
Trumbo said that over his career he thinks his home runs have come in bunches. It's something he has been at a loss to explain, and he realizes that it's something he's better off not putting too much thought into.
"You want to be consistent," he said. "You just play. You go out there and play, and things shake out at the end of the year."
Trumbo's overall production is very consistent.
In 2011, Trumbo hit 29 homers and followed that up with 32 in 2012 and 34 last year.
