SCOTTSDALE, Ariz. -- With a second straight Opening Day start already on his itinerary, Ian Kennedy can take the unsightly results from his second spring start Saturday night in stride, knowing it's all part of a process.

That hasn't always been true for the 27-year-old right-hander, but after allowing four runs on six hits in his three-inning start against a Mariners split squad, there was no reason for concern in Kennedy's mind.

"I think last spring was my first spring when I didn't really have to worry about that, just get ready to the season," Kennedy said. "Coming over here from the Yankees [prior to the 2010 season], I was really trying to make the team. It's a nice luxury to have just to get ready for the season."

Certainly, D-backs manager Kirk Gibson wasn't worried about the numbers on the scoreboard, just that his starter hit his pitch count and accomplished what he needed to in early March.

"He was fine," Gibson said. "He was working on some things. He threw mostly fastballs and threw some changeups later, not many curveballs. He worked on his move today. He worked on throwing inside. His arm feels fine."

Kennedy got his proverbial work in by throwing 45 pitches without recording a walk. The Mariners were attacking Kennedy's fastball early in the count, which kept him from getting much work on his offspeed pitches until his final inning.

"I was really just trying to get my location down," Kennedy said. "I felt my fastball in was better against righties and wasn't leaving anything over the plate, so location's more important for me right now, especially the second outing."

Roberts taking nothing for granted

SCOTTSDALE, Ariz. -- Third baseman Ryan Roberts proved a lot of things to a lot of people last year when he shrugged off a rough 2010, came into last year's Spring Training camp to make a statement and kept on making statements throughout a breakout 2011 season.

And if you think that means Roberts is settling into a comfort zone, knowing his place on the D-backs is secure, think again.

The man known as Tatman for his body art has been taking a mental approach to camp that's every bit as determined as the one he had last year, when he broke camp on the Opening Day roster.

"I've tried to prepare this offseason and come into this season with the same mentality as last offseason," Roberts said. Whatever I did last offseason worked, so I didn't really want to change it. The mentality of it is the same, like I'm still trying to make the team. I want to play like that the rest of my career."

Roberts had his first game off of the spring on Saturday, following a three-run homer that was his third blast of the spring. Those are his only hits in 15 at-bats thus far.

Collmenter to test arm in bullpen session

SCOTTSDALE, Ariz. -- Two days after his Friday start was scratched due to forearm stiffness, right-hander Josh Collmenter will throw a bullpen session Sunday and hopes to remain on track to return to Cactus League action on Wednesday.

Collmenter said Saturday that "everything's fine" and he expects no ill effects from a session of 30-35 pitches Sunday. D-backs manager Kirk Gibson said Collmenter should be fine to make one of Wednesday's split-squad starts.

Whether Trevor Bauer, the No. 3 overall pick in the 2011 First Year Player Draft, gets another start after filling in impressively for Collmenter remains to be seen.

"Don't know that. He falls on Wednesday again," Gibson said.

What Gibson does know is that he'd like to see Collmenter pitch one of those games.

"He'd be ... one for sure if everything goes OK [Sunday]," Gibson said. "Collmenter's going to start one of the games, and somebody else will start the other game."

Worth noting

• Gibson said he took a little tour of Minor League workouts on Friday and liked not only what he saw, but what he heard. "They're all working hard, and I walked by a group of them and said, 'What a great day, you're playing baseball, where would you rather be?' One of them said, 'Over there,' " Gibson said, indicating the Major League side of the facility.

• Barry Enright was roughed up for the second time in as many Cactus League outings, giving up two runs on four hits in his second inning of work after a 1-2-3 sixth on Saturday against the Mariners. Relievers Takashi Saito and David Hernandez each threw a hitless inning.

• A mound meeting between Kennedy and catcher Miguel Montero in the game wasn't exactly to discuss strategy. "He had no idea how many outs there were," Kennedy said with a chuckle about Montero, who jogged off the field with two outs in a game last year. "That's Miggy. He needs a scoreboard on him."
