The Miami Marlins, Oakland Athletics and Arizona Diamondbacks are no longer involved in on-field activities, but that doesn't mean they're completely dormant.

According to CBS' Jon Heyman, the teams agreed on a three-way trade on Saturday:

Teams announce dbacks get heath bell, a's get chris young (OF) and marlins get 3b prospect yordy cabrera. Obvs $ involved — Jon Heyman (@JonHeymanCBS) October 20, 2012

Major League Baseball shed light on another name included in this deal:

BREAKING: @athletics get @cy24_7 in trades that send Heath Bell & Cliff Pennington to @dbacks. @marlins add INF prospect Yordy Cabrera. — MLB (@MLB) October 20, 2012

Pennington hit .215 with six home runs and 28 RBI this season. For a small price, the 28-year-old shortstop is a solid veteran to play in a pinch for Arizona, but could also start next season.

According to MLB.com reporter Joe Frisaro, the Marlins will pick up part of Bell's contract:

None of those guys are named Alex Rodriguez, but this is still a notable trade, especially considering the timing of it. With winter meetings still a ways away, transactions are not common this time of year.

Bell only played one season with the Marlins, and it didn't go well. A 5.09 ERA amounted to 19 saves on the season, despite blowing eight other tries. That's not what you pay a reliever $7 million to do.

He had been the subject of rumors surrounding Rodriguez lately, but we can put those to bed after his move to Arizona.

Perhaps the biggest name in this move is Chris Young. He hit .231 with 14 home runs and 41 RBI this season. He played in very limited action after getting hurt in early September, but he does have some skill. Always a strikeout possibility, Young has a lot of the skills you look for in an outfielder.

Cabrera is the unknown commodity here. The shortstop prospect played in High-A this season, hitting .232 with three home runs. He's still young, so his upside could pay dividends for Miami down the line.

Picking up part of Bell's contract is probably the end of any cash considerations, but we will have to wait and see.

Oakland can be considered the early winner here. Bell could benefit from a change of scenery, and Arizona did need back-end arms, but the 35-year-old reliever is toward the end of his career. He had three straight 40-plus save seasons with San Diego prior to this season, but that was also within the confines of PetCo park.

Young, even for his faults, is still 29 years old. He's hit 20-plus home runs four times, and he could give Oakland some pop in its lineup. Considering the cost, making the move makes sense for the Athletics.
