The Boston Red Sox are "all in" on pursuing Pablo Sandoval, according to an executive with another club.

Sandoval is seeking a six-year contract and would give the Red Sox a left-handed bat while playing a position of great need of third base. Sandoval could also transition to designated hitter to ultimately replace David Ortiz.

"He's more of an American League player," said the executive. "And he can really hit."

Ben Cherington said Tuesday he met the day before with Gustavo Vazquez, Sandoval's agent, and that the sides had a "constructive" conversation.

"We've met with several [agents], including [Vazquez], and had good constructive conversations with a lot of guys already," Cherington said. "All those conversations will continue. I don't expect anything to happen this week, or maybe in the near term. This may play out. I expect many [conversations] to continue over the next few weeks."

The San Francisco Giants have been optimistic about re-signing Sandoval.
