General manager Trent Baalke and other members of the 49ers have reached out recently to holdout Alex Boone, according to multiple sources, but the team's starting right guard remains resolute in his stance.

As it stands now Boone ranks 43rd in the NFL in average salary for guards. He signed his current deal in 2011 when he was a backup at tackle. He's seeking a new deal that will pay him commensurate with a starting guard, his role since the beginning of the 2012 season.

In meeting with reporters on Saturday, Baalke refused to talk about Boone's holdout, including whether the 49ers negotiate with players who are not in training camp. Boone, who went undrafted in 2009, has two years left on his current deal.

“Once again, nothing positive is going to come from discussing any of this, our strategy, how we deal with players, how we deal with this situation or others,” Baalke said. “I've never seen anything positive come from that.”

The 49ers last week restructured outside linebacker Ahmad Brooks' contract, creating an extra $2 million in salary-cap space. Overall, the team has a little less than $10 million in cap space, which doesn't include Boone's $2.59 million cap figure.
