The waiver period for trades before the Sept. 1 roster deadline will come and go without the Cubs having made a deal, according to Major League Baseball sources.
Both Rich Harden and Aaron Heilman, claimed on waivers, by the Twins and Giants, respectively, will continue to toil for the Cubs.
The teams were not able to work out a deal over the 72-period after a team puts in a claim on a player.
If playoff-bound teams add a player after the waiver period of Aug. 31 has passed, they are not eligible for postseason play. Harden and Heilman were just two of hundreds of players claimed and not traded during August, when the highest waiver activity takes place.
August is the month between the trading deadline and the playoff roster deadline. Therefore, you see the most activity of claims.
