By Sunday evening, the Chicago Cubs will have a new outfielder, Chris Heisey, and the Cincinnati Reds will have a new relief pitcher, Carlos Marmol.

You heard it here first.  

Sources are saying that, “Walt Jocketty and Jim Hendry are in serious discussions over a trade involving Chris Heisey and Carlos Marmol.”

The intra-divisional deal is sure to raise more than a few eyebrows.  Teams almost never within their own division—especially when it comes to young talent.

Imagine Marmol giving up a division-winning home run to Heisey.  Or an equally disastrous strikeout of Heisey by Marmol in game 162 with the division title on the line—but both teams seem willing to pull the trigger.

“It is all but a done deal,” another source close to the Reds’ organization told me.

Whether or not the deal is completed before or after the weekend series remains to be seen. 

It is also expected that the Cubs will ask for an additional player, most likely a minor league pitcher, probably either Brad Boxberger or Donnie Joseph.

Marmol’s stuff is electric, there is no doubt about that.  He would immediately fill Nick Masset’s role as the right-handed set-up man to Francisco Cordero.

This season, Marmol has been used in the closer role for the Cubbies.  He currently sports a 2010 ERA of 2.21, striking out 68 in 36.2 IP. 

He has walked 26, but judging by 1.85 strike outs per inning and his ERA, he has not allowed to many of those freebies to score.

Marmol is currently in his first year of arbitration earning $2.125 million.

Heisey is a first-year player who started the season in Triple-A Louisville and was called up and placed on the Major League roster when Chris Dickerson broke the wrist’s hamate bone.

In 2009, Heisey led all of the minor leagues in hits and total bases.

So far this season, in limited action with the big club, the 25-year-old has socked four HRs and batted .278 with a .385 OBP while slugging .574 in 58 at-bats.  Coming into 2010, he was ranked the fourth-highest Reds’ prospect by Baseball America .

Financially, this trade makes sense because Heisey is making the league minimum and has three or four years left before he is eligible for arbitration.

The Cubs would probably start playing Heisey in center and very actively shopping Marlon Byrd.

Boxberger has been used as a starter for most of the season, though his future may well be as a relief pitcher.  Drafted in 2009 as a first-round supplemental pick out of USC, he was named Baseball America’s ninth-overall prospect in the Reds’ organization.

Joseph, out of the University of Houston, is another pick from last year’s draft.  He has been used exclusively as a relief pitcher between low- and high-A ball so far this season, and has looked more than impressive with an 0.90 ERA, 0.78 WHIP, and a .139 BAA.

Joseph, another top prospect in the Reds’ farm system, was ranked No. 21 at the beginning of the season by Baseball America, but has undoubtedly climbed the ladder with his performances in Dayton and Lynchburg.

So, Reds fans, get ready for the lighting arm of Carlos Marmol, and Cubs fans, get used to seeing Chris Heisey in center. 

It’ll be tough to swallow because there is no doubt the trade bite both teams few times over the coming years.
