Baseball's top teams are keeping a close eye on Chicago while they search for help down the stretch.

An increasing number of scouts have filled the seats behind home plate at Wrigley Field and U.S. Cellular Field ahead of the July 31 non-waiver trade deadline.

While the Cubs and White Sox are well off the pace in their respective divisions, Chicago remains a pivotal place in the pennant race because of the available players who could play a key role for a contender down the stretch.

Theo Epstein, the president of baseball operations for the Cubs, says "Our job is to be realistic about where we are and where we're going and act accordingly."
