"It may not be official or intentional, but the Cubs' youth movement is in full gear just two months into the season.

On Tuesday, when left fielder Alfonso Soriano (quadriceps) became the fifth Cub in 10 days to go on the disabled list, it left Kosuke Fukudome as the only outfielder on the active roster who hasn't spent time in the minors this year.

The Cubs recalled Tyler Colvin from Class AAA Iowa, and he'll start today, manager Mike Quade said. Colvin played all three outfield spots and first in 12 games for Iowa.

Meanwhile, Tony Campana started his sixth straight game in center in place of the injured Reed Johnson, who had replaced the injured Marlon Byrd.

Infielder Blake DeWitt, who took over for Soriano on Monday after Soriano pulled up with the injury running out a hit in the first inning, started Tuesday in left and could see more time there.

''We'll mix and match and do some things,'' said Quade, who included Colvin in his center-field mix. ''Fuke's done a real good job in right, and I'll probably try to leave him there.''

The Cubs say they don't think Soriano's injury is serious enough to keep him on the DL longer than the required 15 days. Soriano is hitting .271 and leads the team in home runs (12) and RBI (29)."
