"Report is not accurate," MacPhail wrote to MASNSports.com.
Jim Bowden of MLB Network Radio reported last night, via Twitter, that Guerrero was close to accepting a deal from the Orioles.
Guerrero, who turns 36 in February, hit .300-29-115 last year with Texas and is a free agent. He finished fourth in the American League in RBIs, ninth in homers and was 11th in the MVP voting.
While MacPhail has often said "one phone call can change things" and no one from the Orioles is saying a possible Guerrero signing is 100 percent out of the question, it certainly appears that no signing is imminent. The O's have not had recent discussions with Guerrero, sources say.
