The Chicago Cubs will acquire Austin Jackson from the Seattle Mariners.

Jackson cleared trade waivers and the Cubs can place him on their postseason roster because he was acquired before Sept. 1.

Seattle will receive a player to be named later and a $211,000 international signing slot. Chicago will receive some cash to offset what is left on Jackson's $7.7 million salary.

The Kansas City Royals will acquire Jonny Gomes in a trade with the Atlanta Braves.

Atlanta will send cash to Kansas City and receive Minor League infielder Luis Valenzuela in return.

Gomes signed a one-year, $4 million deal with the Braves this past offseason.

The New York Yankees claimed David Robertson off waivers, but the Chicago White Sox have pulled the reliever back.

The two clubs didn't have legitimate trade talks over the weekend.

The deadline to make a team's postseason roster is Monday, so additions are unlikely in September.

The Mets are on the verge of acquiring right-handed reliever Addison Reed from the D-Backs to bolster the bullpen, a source told ESPN.com.

Reed, 26, is 2-2 with a 4.20 ERA in 38 appearances for Arizona this season.

An unknown club has claimed Craig Kimbrel on waivers, according to a report by Ken Rosenthal of FOX Sports.

The San Diego Padres, however, have no intention of trading the reliever.

Kimbrel is earning $9 million as part of a four-year, $42 million contract extension signed with the Atlanta Braves.

Two more bullpen options may be available via trade as the deadline to make a postseason roster nears.

The Milwaukee Brewers have placed Francisco Rodriguez and the Baltimore Orioles have placed Darren O'Day on revocable waivers.

Both Rodriguez and O'Day were placed on waivers Wednesday, which means they should clear on Friday afternoon.

The New York Mets are in need of a left-handed reliever, but they aren't likely to add to the bullpen via trade in the coming days.

A source told Anthony DiComo of MLB.com that a trade for a reliever is "unlikely."

Jose Reyes, who was acquired by the Rockies in the trade that sent Troy Tulowitzki to the Blue Jays, said Saturday that he'd welcome a trade from Colorado. Reyes, 32, is owed $56M through 2017, so the rebuilding Rockies likewise are seeking the same.

"I'm at the point in my career that I want to win," Reyes told the Denver Post. "I say it over and over. I want to win. I don't want to spend the rest of my career on a last-place team. That's not the kind of player I feel like I am."

The Toronto Blue Jays have traded Randy Wolf to the Detroit Tigers in exchange for cash considerations.

Wolf, 38, has excelled at the Triple-A level this season. The left-hander has a 2.58 ERA and Detroit is in need of an arm with recent injuries to Anibal Sanchez and Daniel Norris.

The San Francisco Giants have acquired Marlon Byrd from the Cincinnati Reds.

Cincinnati will receive Double-A right-hander Stephen Johnson.

The Giants will likely option Ryan Lollis to Triple-A Sacramento to make room for Byrd.
