Miami Marlins trade rumors: Wei-Yin Chen, Yaisel Sierra among pitching targets

Miami officially signed Edwin Jackson on Saturday and the club might not be done. The Marlins are interested in Wei-Yin Chen and prospect Yaisel Sierra, according to FOX Sports' Ken Rosenthal.

Since the end of the season, the Marlins have been seeking starting pitching depth. Heading into 2016, the organization has Jose Fernandez, Tom Koehler and Jarred Cosart slotted in the starting rotation. Jackson could be a starter, but the Marlins could also use him as a long relief option.

The Marlins were linked to Chen earlier this off-season, but since the organization does not have a great relationship with his agent, Scott Boras, it might be challenging to get a deal done. The club has considered moving Fernandez and outfielder Marcell Ozuna, both Boras clients, this winter. But the Marlins could still try and add Chen.

While Rosenthal notes a deal with Chen is "not imminent," the Marlins do not have a top of the rotation starter to complement Fernandez. Chen, who pitched to a 3.34 ERA and 4.16 FIP over 191.1 innings with the Orioles last season, could be an ideal candidate since the Marlins do not currently have a left-handed starter in their rotation.

If the Marlins were to sign Chen, they would lose a draft pick. However, since their seventh overall pick is protected, the No.46 pick would be lost.

Miami has been linked to Chen in the past, but this is the first time the club is known to be interested in Sierra. Rosenthal believes Sierra is expected to sign a deal worth more than the 7-year, $27 million deal Raisel Iglesias received from the Reds. While the Marlins are interested, they might not be willing to pay Sierra accordingly.

Ozuna could be traded for a young starting pitcher this off-season, but the Marlins would be losing offense by moving him. Derek Dietrich would reportedly emerge as the starting left fielder and platoon with a right-handed hitting outfielder if Ozuna is traded.

Under new Manager Don Mattingly and Hitting Coach Barry Bonds, the Marlins want to compete immediately in 2016. The organization is still seeking pitching depth, and Chen and Sierra remain plausible options.
