The Pittsburgh Pirates have acquired Chris McGuiness from the Texas Rangers in exchange for Miles Mikolas.

Texas also designated outfielder Rafael Ortega for assignment.

The New York Mets have remained in contact with the Milwaukee Brewers, Baltimore Orioles and Pittsburgh Pirates about Ike Davis.

The Mets haven't been able to pry top pitching prospect Eduardo Rodriguez away from the Orioles in trade talks.

Rodriguez, 20, posted a combined 3.41 ERA with 7.8 K/9 and 3.0 BB/9 in 145 innings between Class-A Advanced and Double-A in 2013.

The Pittsburgh Pirates have interest in acquiring Ike Davis and Mitch Moreland via trade.

The Pittsburgh Pirates still expect A.J. Burnett to return for one more season.

Pittsburgh has entertained signing other veteran starters in the event Burnett retires, or signs elsewhere.

"There's no reason for [Burnett] not to be back," said one Pirates official. "He can still pitch at a high level and we think he only wants to play for us. Seems like a no-brainer."

The Pittsburgh Pirates have reportedly re-signed Clint Barmes to a one-year deal.

The deal is reportedly worth $2 million.

The Pittsburgh Pirates have agreed to a one-year, $5 million deal with Edinson Volquez, pending a physical.

Volquez, 30, went 9-12 with a 5.71 ERA with the Los Angeles Dodgers and San Diego Padres in 2013.

The Pittsburgh Pirates have signed Charlie Morton to a three-year, $21 million contract extension, according to a source.

The guaranteed contract will pay Morton $4 million in 2014. His salary will increase to $8 million in 2015 and 2016, according to the source.

A club option for 2017 could increase the overall value of Morton's contract to $30 million.

The Miami Marlins are telling clubs they will trade Logan Morrison.

Miami finalized a deal with Garrett Jones, putting the wheels in motion for a Morrison trade.

The Pittsburgh Pirates, Toronto Blue Jays, Tampa Bay Rays and Baltimore Orioles have all been linked to Morrison.

The Pittsburgh Pirates plan to meet with Terry Bross, the agent for Bronson Arroyo, at the Winter Meetings this week.

Pittsburgh has some uncertainty in their rotation given A.J. Burnett's pending decision on retirement.

The Pittsburgh Pirates have acquired Chris Stewart from the New York Yankees in exchange for a player to be named later.

In 109 games with the Yankees in 2013, Stewart batted .211 (62-for-294).

He was acquired by the Yankees from the San Francisco Giants on April 4, 2012 in exchange for RHP George Kontos.
