Bay Area Notes: Callaspo, Colon, Arroyo, Vogelsong

Here's the latest from both the Athletics and Giants…

• The A's are scheduled to meet with Adam Katz, Bartolo Colon's agent, this week to discuss a one-year deal for the veteran righty, CSNBayArea.com's Joe Stiglich reports.  Colon has shown an interest in returning to Oakland but a number of teams would be interested on Colon for just a one-year commitment.
• Also from Stiglich, he wonders if Alberto Callaspo could be expendable now that Nick Punto has been signed to increase the Athletics' infield depth.  Callaspo is set to platoon with Eric Sogard at second base next season, but Callaspo's salary ($4.875MM) is a high one for the payroll-conscious A's.
• Bronson Arroyo has been linked to the Giants in trade rumors, so CSNBayArea.com's Andrew Baggarly breaks down the pros and cons of an Arroyo signing for San Francisco.
• The Giants are "continuing a dialog" with Ryan Vogelsong's representatives, assistant GM Bobby Evans tells Hank Schulman of the San Francisco Chronicle (via Twitter).
