West Notes: Hoes, Doolittle, Rockies, Gregorius

It's been a busy day for baseball's Western divisions, with the Mariners agreeing to sign Corey Hart and acquiring Logan Morrison as well as the A's trading Jerry Blevins to the Nationals. Here's more out of each division…

• Astros outfielder L.J. Hoes has switched agencies, MLBTR's Tim Dierkes tweeted last night. Formerly a client of Excel Sports Management, Hoes will now be represented by the MVP Sports Group.
• The Nationals asked the Athletics about Sean Doolittle before acquiring Blevins, but Oakland didn't want to part with Doolittle, according to MLB.com's Jane Lee (on Twitter).
• The A's are excited about Drew Pomeranz as a potential replacement for Blevins, tweets Ken Rosenthal of FOX Sports. Rosenthal adds that Oakland's interest was piqued by a handful of strong relief appearances by Pomeranz at the end of the season.
• Troy Renck of the Denver Post reports that the Rockies still want to add another bat, but relief help appears to be their priority. Colorado's prefernce is to add a left-handed arm, which is why they were so interested in Sean Marshall earlier in the week (Twitter links).
• Diamondbacks shortstop Didi Gregorius has drawn some interest from the Yankees, tweets Joel Sherman of the New York Post. The D-Backs reportedly could use their shortstop surplus to land a starting pitcher, but the Yankees are in the market for starters themselves and don't seem to be a good fit in that regard.
