Twitter was atwitter last night with news of an impending trade that would send Carlos Marmol to the Angels for Dan Haren. We would be freed from the insanity of the Marmol roller coaster experience any time he came in to close a game, and receive a real, bona fide starting pitcher. But then the Cubs said no. Let MLBTR guide you through the ups and downs of the rumor mill last night.

9:39pm: The Red Sox were said to also have interest in Haren but it doesn’t appear that they will trade for him either, tweets Danny Knobler of CBSSports.com.  Meanwhile, a source tells Bruce Levine of ESPNChicago.com (via Twitter) that the deal is not necessarily dead but is unlikely at this point.

9:27pm: Marmol would have approved a trade to the Angels, but the Cubs pulled the deal off of the table, a source tells Ken Rosenthal of FOX Sports (via Twitter).  The Angels are still talking with other clubs about Haren as they close in on the 11pm CST deadline to exercise his $15.5MM option.

9:20pm: The trade will not take place, a Cubs source tells Carrie Muskat of MLB.com (via Twitter).

8:42pm: The deal will take place if Marmol agrees to join the Angels, a source told Ken Rosenthal of FOX Sports (via Twitter).

8:29pm: The two sides haven’t agreed to a trade, according to Ken Rosenthal of FOX Sports (via Twitter).  The Cubs did ask Marmol if he would waive his no-trade clause to go to the Halos, but the Angels are still speaking with other clubs (Twitter link).

8:09pm: The Angels and Cubs may be waiting on MLB approval because of the money being exchanged, tweets Mike DiGiovanna of the Los Angeles Times.

7:56pm: Alden Gonzalez of MLB.com (via Twitter) hears that the deal has not been completed and the Angels are still active in discussions with more than one team.

6:49pm: The Cubs have acquired Dan Haren from the Angels in exchange for Carlos Marmol, confirms Bruce Levine of ESPNChicago.com (via Twitter).  The deal was first reported by Yancen Pujols of El Caribe (via Twitter, Spanish link).

It was jubilation followed by anger followed by sadness followed by numbness. But it looks like there’s a decent chance Carlos Marmol will be traded this winter.

Gordon Wittenmyer suggested a couple possibilities for the deal falling through.

One report suggested money may have been the hang-up.

The Angels declined Haren’s $15.5 million option for 2013 at Friday’s 11 p.m. deadline making him a free agent. They had shopped him for much of the week.

Because of the $3.5 million buyout clause on the option, that sunk cost was considered in play as a cash offset for any club trading for Haren.

But Marmol is due $9.8 million in 2013, the final season of a three-year, $20 million deal, which wouldn’t seem to require a cash offset from the Angels.

Money’s always a problem with these deals, especially when they have to be sent to the commissioner’s office for approval. But a more likely story is that Haren’s medical reports weren’t what the Cubs were hoping to see.

A potentially more significant issue with Haren, 32, is the high mileage on his right arm as he comes off the first season in which he spent time on the disabled list.

Haren pitched at least 216 innings for seven consecutive seasons before being plagued by lower-back tightness in the first half and eventually going on the DL in July.

When he came back his once-94-mph fastball was more often in the upper-80s and he relied more on location than power for what success he had.

Oh well. Welcome back, Carlos Marmol.
