Hoyer keeping close tabs on waiver wire

CHICAGO -- Cubs manager Joe Maddon said he has a better feel for how to make the roster work, but general manager Jed Hoyer said Friday they are continuing to look for additions.

Hoyer said the Cubs, who began play on Friday with a 4 1/2-game lead for the second National League Wild Card spot, have been busy checking the waiver wire.

"It's been tight on the waiver wire," Hoyer said. "Teams have been active claiming guys. We'd be open to moves that made us better. We've got a ways to go to get to the end of the month to make those moves. We'll pay attention to what we may need to get through the last month."

Hoyer said there was "nothing imminent" regarding player additions.

"I'm really pleased with what we have," Maddon said. "We're finally figuring out how to fit all the different pieces together. That matters. You get that nice little flow, everybody knows what's going on."

Hoyer did admit that if the club were to add someone, it would want a player who will not only fit the Cubs' needs but also not upset the chemistry on the team.

"With a team like this that's playing well, you have to pay attention to the team dynamic but also try to think ahead and what things do we need in September, what things we need down the stretch," Hoyer said.
