According to this tweet, the O's have come to terms with Vladimir Guerrero on a one-year deal for $8 million.
An Orioles source tonight confirmed the agreement.
Earlier today, a team source said the O's and Guerrero's representatives have had "ongoing" discussions this week. Now those discussions have indeed paid off.
Reached via e-mail, O's president Andy MacPhail said he could not confirm or deny a signing that required a physical. He does not comment publicly on any signings before the completion of a physical and an official announcement by the club.
More details as they become available.
