The Cubs and White Sox are in varying states of development, harboring eclectic groups of transient veterans and emerging young players.

In the cases of many of these players, it will be: Now you see them, now you don't.

In the meantime, the work-in-progress teams remain on public display against each other this week, and Tuesday night the Sox won their second straight from the North Siders, 5-1, before a crowd of 34,305 at Wrigley Field.

"Our approach wasn't very good, and our guys know that," Cubs manager Rick Renteria said.

Gordon Beckham collected four hits, including a homer off Neil Ramirez to put the Sox ahead 2-1 in the eighth.

"It was great. He has been trying to find that swing and tonight was it," Sox manager Robin Ventura said of the slumping Beckham's breakout game. "He made a couple of adjustments in batting practice … felt good … I mean, it looked good. He hit the ball all over the place. With him you always want to get that going. He has been trying to find that since he came off the (disabled list)."

Moises Sierra, a last-minute addition to the starting lineup when Adam Dunn was scratched, also collected a career-high four hits.

Sox starter Hector Noesi went five innings and tamed the Cubs on four hits while allowing one run. He struck out six and walked one.

"(Noesi) threw great," Ventura said. "Even the last game he threw — he got through three (innings) and then that little bump with four … but he's stretching it out where he's throwing more pitches. He's making that adjustment, really, on the fly. It's impressive that he's able to step in and give us that kind of effort."

The Sox padded their lead with a three-run ninth on with RBI doubles from Tyler Flowers and Jordan Danks.

Cubs reliever Pedro Strop left with a groin injury as Carlos Villanueva took over and retired the final two batters. Strop, who said he initially injured his groin five days ago during lunge drills, is scheduled for an MRI on Wednesday.

Sox relievers Zach Putnam, Scott Downs and Daniel Webb throttled the Cubs and Putnam earned the victory.
