AL West Rumors: Castro, Astros, Rangers

The Astros are receiving significant interest in catcher Jason Castro, and interest could pick up once big free agents like Brian McCann and Jarrod Saltalamacchia go off the board, writes Jon Heyman of CBSSports.com.  Their interest in trading Castro isn't known, but Houston is said to like catching prospect Max Stassi very much.  Heyman sees the Yankees, Rangers, Red Sox, Blue Jays, Angels, Rockies, and Twins as teams that could possibly have interest if Castro is on the block.  Here's more out of the AL West..

• The Mariners are more immersed in the Carlos Beltran–Jhonny Peralta–Kendrys Morales market than Jacoby Ellsbury at this point, tweets Jerry Crasnick of ESPN.com.
• Brian McTaggart of MLB.com (Twitter link) doesn't see the Astros trading Castro.  Even though Castro is starting to make some money – the catcher is projected to earn $2.2MM in arbitration this year – they're not deep enough at catcher to lose him and the club needs to take a step forward.
• Richard Durrett of ESPNDallas.com examined Carlos Ruiz as a possible fit for the Rangers if they don't land top catcher Brian McCann.
• More from Durrett, who believes that Jurickson Profar's trade value hasn't decreased much despite a down year in 2013.
• The Angels' best bet for acquiring quality pitching via trade would be to part with Mark Trumbo, even though losing him would hurt, writes Alden Gonzalez of MLB.com.
