SCOTTSDALE, Ariz. -- Chad Tracy was a little uneasy the last few days as he waited to see if he had made the Cubs' Opening Day roster.

"I've never been in this situation before," Tracy said Tuesday. "As a kid, you're doing the whole big league camp thing and you don't expect to make the team. There's expectations as you progress in your career. It's a little different. I wasn't used to these emotions and getting stressed."

He can relax now. The Cubs picked Tracy for the final roster spot over Kevin Millar, opting to keep a left-handed bat who can play the corner infield spots. On Tuesday, he looked more at ease when he smacked his first spring homer with two outs in the eighth, a two-run shot.

"You never know what to think," said Tracy, who found out before Tuesday's game. "Your nerves are a little high, a little on edge. Now, hopefully, I can settle down."

Tracy had been in the D-backs' system until this year and was a non-roster invitee in the Cubs' camp. How would he assess his spring?

"I'm not going to say it went really well," said Tracy, who was batting .243. "I had some good at-bats, some bad at-bats. I proved I could play third base again, which is one of the reasons I'm still around here now. Hopefully, they have faith I can play either corner and help the team."

Tracy has primarily played third this spring but will start at first Wednesday at Maryvale Baseball Park in one of the Cubs' split-squad games. The Cubs broke camp last year without a legitimate backup at third and it hurt them when Aramis Ramirez missed two months because of a separated shoulder. Ramirez has played 11 games this spring and been slowed by a sore right tricep.

A career .302 pinch-hitter, Tracy does have experience coming off the bench.

"I'm not going to act like I know the secrets to pinch-hitting," Tracy said. "There is something to having the experience and to have seen some of the guys coming out of the bullpen in the National League.

"I've said it all along, it's one of the toughest jobs in the big leagues. The biggest thing is being prepared and knowing what these guys do. The key is being aggressive and going up there and finding your pitch early enough to where he can't get to his stuff where he can get you out. You have to battle. You try not to let him get you before you get him."

Gorzelanny tunes up with seven innings

SCOTTSDALE, Ariz. -- Tom Gorzelanny may have the fifth starter spot locked up on the Cubs for now, but he still approached his start Tuesday as if he has to earn it.

Gorzelanny gave up three runs on eight hits over seven innings, including a two-run homer by former Cub Mark DeRosa, in Chicago's 5-3 win over the Giants.

"I still went out there trying to do good and trying to do my job," Gorzelanny said. "I don't think just because I got the job it's time to relax. That's when you get in a lot of trouble. You want to go out there and continue to get better and work on stuff and be ready to pitch well when the season starts."

Gorzelanny edged Sean Marshall for one of the two openings in the Cubs' rotation and will make his next start April 10 in Cincinnati. Tuesday was a good tuneup.

"I felt like I did a good job of throwing strikes and keeping the ball in the zone," Gorzelanny said. "One pitch was unfortunate and DeRosa hit it, and that happens and I was able to come back from that."

Tuesday, the Cubs also said goodbye to Kevin Millar, who was released.

"The way [Millar] was in the clubhouse, there aren't many guys you can say are like this guy," Gorzelanny said. "Kevin brought a lot of laughter to the clubhouse but he was serious. He wasn't just joking around, he was there to work. He's a gamer.

"I think he brought the fact that we're here to have fun, this is a game, this isn't a job -- well, it is a job, I guess," Gorzelanny said, catching himself. "I think I should rephrase that, that this isn't work, it's a game and we're out here to have fun and enjoy the game but also take it seriously. He was a great influence on a lot of guys, and the way he went about his work and being a good teammate, there's a lot for guys to learn from."

The Cubs still have 27 on the spring roster, which includes 14 pitchers. Ted Lilly and Angel Guzman are both expected to be placed on the disabled list on Opening Day to reduce the number to 12. Lilly, coming back from arthroscopic shoulder surgery, made his second start in the Minor League camp Tuesday, throwing 45 pitches. Guzman is out for the season after needing arthroscopic surgery on his right shoulder in March.
