NL West Notes: Rockies, Spilborghs, Winfree, Padres

Here's a look at a handful of items out of the National League West..

• There will be an agreement in place to prevent the raiding of the Padres' front office by the Cubs once the departures of Jed Hoyer and Jason McLeod are official, a team source tells Dan Hayes of the North County Times (via Twitter).
• Rockies third baseman Ian Stewart and outfielder Ryan Spilborghs would like to play winter ball after disappointing seasons, but they are on the fence because of their arbitration-eligible status, writes Troy E. Renck of The Denver Post.  Both players are non-tender candidates and could wind up as free agents on December 12th.
• The Diamondbacks added infielder David Winfree to their major league roster, according to their official Twitter page.  Arizona also did some roster shuffling yesterday when they outrighted Sean Burroughs, Alberto Castillo and Robby Hammock to Triple-A.
• With Jed Hoyer expected to join Theo Epstein in Chicago, Tom Krasovic of Inside The Padres gives his impression of Hoyer as a GM.  While some Padres fans are upset with Hoyer for leaving the club, Krasovic believes that the soon-to-be 38-year-old is simply seizing a rare opportunity.
• The Padres don't expect to lose scouting director Jaron Madison to the Cubs if Hoyer and Jason McLeod join the organization, a team source told Dan Hayes of the North County Times (via Twitter).
