Rangers roundup: Justin Upton, Michael Bourn, A.J. Pierzynski

We've had a ton of content since the winter meetings, so it's easy to miss stuff. Here's the latest from the Texas Rangers:

• The Rangers are still on the prowl for a power bat to help replace the production of Josh Hamilton and Mike Napoli, but it is unclear who they are still looking at. Texas is rumored to be more interested in making a move on the trade market, so Justin Upton and/or Jason Kubel of the Diamondbacks could be in play, but the squad has also shown interest in free-agent outfielder Michael Bourn.
• Texas finally made a splash in the free-agent pool, signing veteran catcher A.J. Pierzynski to a one-year, $7.5 million contract. To make room for the new catcher, the club designated fellow backstop Luis Martinez for assignment.
• Former Rangers owner Brad Corbett -- who ran the club from 1974-1980 -- passed away in his sleep on Christmas Eve. He was 75 years old.
• Right-handers Colby Lewis and Neftali Feliz are both recovering well from their respective arm surgeries. Lewis' rehab is progressing quick than expected, and he could return as early as May if all continues to go well. His early return could keep the Rangers from adding another outside arm to the rotation. Feliz will be out until well after the All-Star break.
• The Rangers claimed catcher Eli Whiteside off of waivers and re-signed infielder Brandon Snyder to a minor-league deal.
