MILWAUKEE -- Tyler Colvin will continue to take grounders at first, but the rookie outfielder is not expected to see any action there any time soon.
"Things are going well," manager Mike Quade said, "and I'm not interested in pulling the trigger on that. I'd like him to keep working there. I teased him yesterday and said, 'You never know, pal. Be ready.' We don't have the need that I thought we might when Derrek [Lee] left."
Lee was traded Aug. 18 to the Braves, leaving a gap, but Xavier Nady has handled first base, and the Cubs also called up Micah Hoffpauir.
Colvin hasn't played first base since his sophomore year in college, and it was only part-time then.
"It's going to be a new experience for him," Quade said of Colvin playing first. "I don't want him to show up tomorrow and, bang. Like I do with all of them, I want to give him a head's-up. Nady's making it tough for me to do that."
Silva scratched, Samardzija to start Monday
MILWAUKEE -- Carlos Silva was scratched from Monday's scheduled start against the Cardinals because of a right elbow strain, and Jeff Samardzija will make his first big league start of the season in his place.
Silva (10-6, 4.22 ERA) reported the soreness during batting practice on Sunday.
Samardzija (0-1, 18.90 ERA) had been penciled in for next Saturday against the Marlins. He began the season with the Cubs but was sent down to Triple-A Iowa after four outings. In 35 games with Iowa, including 15 starts, he was 11-3 with a 4.37 ERA.
"It sounds good. I'm ready to go and my arm feels good. I'll just get out there and just really attack," said Samardzija, who has not thrown in a game since being called up last Tuesday. "I don't think there's anything to change or anything to look at."
Samardzija made two starts last season with the Cubs among the 20 games in which he appeared, and he gave up 10 earned runs in 8 1/3 innings in those games. He has been looking forward to getting another chance.
"It's definitely been something that's been on my mind for a long time," he said. "They use the term, 'You get hungry,' or whatever, whatever you want to say. When you spend the whole year down there in Triple-A, this is definitely something you look forward to and get excited about, for sure."
Samardzija was watching the NFL games in the clubhouse before and after the game. Does the former All-America wide receiver for Notre Dame ever think about playing football?
"Nope," he said.
As for Silva, he was to return to Chicago to be examined by the team's orthopedic specialist, Dr. Stephen Gryzlo.
In other pitching news, left-hander Tom Gorzelanny had his second bullpen session on Sunday at Miller Park and could be close to returning to the rotation. The only question is when.
With Samardzija now in the mix, the Cubs have a six-man rotation, although that may change depending on Silva's status. Gorzelanny, who has been rehabbing since being hit on the left hand by a line drive on Sept. 1, threw 40 pitches on Sunday.
Manager Mike Quade said that he will meet with pitching coach Larry Rothschild on Monday to discuss their options.
Quade a man of numbers
MILWAUKEE -- Mike Quade, having worked in the Oakland system, is well versed in Sabermetrics, the system of analysis featured in the book "Moneyball," which is being made into a movie.
Quade likes looking at stats, and he uses the numbers available to determine his lineups.
"I'm not a Sabermetrics guy, but I'm smart enough to know numbers do matter, and I pay attention to it," Quade said.
So what's his favorite number? On-base percentage? Batting average with runners in scoring position and two outs on Saturdays?
"When the Cubs have more runs than the opposing club, that's probably my favorite stat," he said.
