6:54pm: If the Dodgers get Marmol, the Cubs would pay most, if not all, of the $5MM owed to him tweets Ken Gurnick of MLB.com. The Cubs might also get a player recently removed from the Dodgers' roster. Gurnick doesn't specify, but the recently DFA'd Matt Guerrier would fit the bill.

4:27pm: The Dodgers are closing in on a trade to acquire Carlos Marmol from the Cubs, according to Bruce Levine of ESPN Chicago. Marmol was designated for assignment by the Cubs last week.

There are some hurdles left, as the Dodgers are on Marmol's limited no-trade list, and he's owed about $5MM for the rest of the season. The Dodgers are expected to absorb some of the salary and it's unclear which player or players might be heading to Chicago, according to Levine.

Marmol has a 3.50 ERA with a healthy 11.7 K/9 in 542 1/3 career innings, but he's also averaged 6.1 walks per nine innings pitched. Those command problems have worsened over the past two seasons, and his strikeout rate has dropped in 2013. He is in the final season of a three-year, $21MM extension he signed in early 2011.
