AL West Notes: Fister, Rangers, Pena

On this date last year, the Angels acquired Dan Haren from Arizona for Patrick Corbin, Tyler Skaggs, Rafael Rodriguez and Joe Saunders. The Angels finished with a losing record in 2010, but they're in contention now and Haren has been excellent, posting a 3.01 ERA with 7.3 K/9 and 1.7 BB/9 in 239 innings for the Halos. Meawhile, Skaggs has developed into one of the top prospects in the game and Corbin is highly-regarded as well. Here's the latest from the AL West… 

• Mariners starters Felix Hernandez and Doug Fister told Danny Knobler of CBSSports.com that they don't want to be traded.
• Rangers manager Ron Washington confirmed to T.R. Sullivan of MLB.com that he'd like to see the Rangers fortify their bullpen before the trade deadline.
• The Mariners appear to believe Fister is better than Jason Vargas, so they may not want to deal Fister, according to Knobler (on Twitter). 
• Rangers assistant GM Thad Levine told Jim Bowden of MLB Network Radio that Texas continues discussing a contract extension for left-hander C.J. Wilson (Twitter links). Wilson, who hits free agency after the season, received a contract offer from the Rangers in March.
• Levine also confirmed that the Rangers are looking for bullpen help and a left fielder. 
• The Mariners, A's, Brewers and Giants have looked at free agent slugger Wily Mo Pena, according to Jon Heyman of SI.com (on Twitter). The Diamondbacks recently released Pena, who hit five homers in 46 plate appearances this year.
