RP Kevin Gregg
Plucked from the scrap heap after being released by the Dodgers shortly after the start of the season, the 35-year-old Gregg has enjoyed a career renaissance of sorts for the Cubs since returning to the closer's role he filled on the North Side back in 2009.
He was 17-of-19 on saves with a 1.95 ERA through his first 33 appearances, but he has struggled of late, converting 5-of-7 saves with a 6.30 ERA in his last nine outings.
That said, any contender looking to pick him up likely would not look for him to close, and he's a veteran arm with late-inning experience, so the Cubs should be able to find a taker.
C Dioner Navarro
Signed to a one-year, $1.75 million deal to be the Cubs' backup catcher, Navarro had seen just 369 total at-bats over the prior three seasons (2010-12), hitting .211/.279/.325 with eight home runs.
He's improved significantly upon those numbers this season though, hitting .289/.363/.500 with nine home runs and 20 RBI in just 152 at-bats.
Perhaps his most attractive stat as a trade chip is the fact that he's 6-for-19 with two home runs and four RBI as a pinch-hitter this season. As good as he's been, the Cubs may very well wind up holding onto him to bring him back as the backup next season.
RP Matt Guerrier
Acquired from the Dodgers for Carlos Marmol in a swap of underperforming, overpaid relievers, Guerrier has roughly $1.4 million left on his contract this season in the final year of a three-year contract.
In 34 games with the Dodgers, he had a 4.80 ERA and 1.467 WHIP. He's been much better since joining the Cubs. He's pitched in 14 games since coming over on July 2, posting a 2.19 ERA and 0.973 WHIP.
Teams may be reluctant to take on that remaining salary, but if he clears waivers, the Cubs may be able to eat most of his remaining contract and flip him to a contender for a low-level prospect.
3B Cody Ransom
Another scrap-heap find, Ransom was selected off waivers from the Padres back in April. He played his way into part-time at-bats in a platoon with Luis Valbuena at third base.
Through June 18, he had a .906 OPS with eight home runs and 15 RBI in 88 at-bats, but his production has fallen off drastically since. From then on, he's hit just .129 with a .540 OPS since and has lost at-bats as a result.
He likely won't interest any contenders, but he does have the defensive versatility to play all four infield positions.
CF David DeJesus and SP Carlos Villanueva
Both DeJesus ($4.25 million) and Villanueva ($5 million) are signed through next season, so teams looking for a rental player for the final two months are far less likely to have any interest in them.
That said, DeJesus remains a solid on-base guy who is capable of hitting atop a lineup, and Villanueva has pitched moderately well as both a starter and reliever this season.
For a team looking to make an addition that benefits them now and in 2014, those guys could be of interest. But the Cubs aren't likely to get much of a return unless they foot most of the bill.
