The Baltimore Sun’s Roch Kubatko and Joe Christensen are reporting that free agent 1B Richie Sexson (above) has passed a physical examination performed by Mariners doctors and will sign a four year, $48 million contract with Seattle sometime tomorrow.

Kubatko and Christensen also claim that after being rebuffed by Sexson, Baltimore has turned its attentions to Marlins righty A.J. Burnett, as well as continuing to monitor the status of Carlos Delgado.

Running out of options at first base, they remain interested in Carlos Delgado and again contacted agent David Sloane Tuesday, though a source close to the negotiations referred to them as “kind of a housekeeping sort of discussion.” Sloane boarded a plane Tuesday night for his South Florida home, which is located about 20 minutes from the Orioles’ spring training site.

Baseball insiders speculate that Delgado is waiting to see if the New York Yankees enter the negotiations. His four-year, $68 million contract expired after the season, and it’s believed that he wants to avoid taking a sizable pay cut.

SS Royce Clayton, who didn’t quite make people forget Ozzie Smith, signed a one-year deal worth $1.3 million with Arizona.
