Giants Notes: Zito, Wilson, Theriot, Romo

Giants pitcher Barry Zito says that he would be open to a contract extension and wants to stay a Giant until he retires, tweets Hank Schulman of the San Francisco Chronicle.  The left-hander is entering the final year of his seven-year, $126MM deal, which includes a $7MM buyout for his option on the 2014 season.  Zito can have the full $18MM option vest with 200 innings of work in 2013.  He hasn't reached that total since 2006, but he has come within eight innings of 200 in three of his seasons in San Francisco.  Here's more on the Giants, courtesy of Schulman..

• General Manager Sabean says he and Brian Wilson just aren't on the same page, Schulman tweets.  Wilson wants more guaranteed money in the deal while the Giants want something heavily based on incentives. 
• Sabean said he "lost contact" with Theriot after a winter meetings overture, according to Schulman (on Twitter).  Sabean also says that he is open to talking about a long-term deal with Buster Posey.  If the Giants start things up with Theriot again, they'll have competition from the Indians, Rangers, and others.
• If Sergio Romo pitches a true closer's workload, his two-year, $9MM deal could rise to $10.5MM in total with incentives and escalators for games finished, Schulman tweets.
