The New York Yankees have reached a tentative agreement with Richie Sexson, who was released by the Seattle Mariners a week ago.

Sexson fits in New York because the Yankees needed a right-handed slugger to match up against left-handed pitching -- and Sexson had a .344 average against lefties this year.

Assuming the deal is completed, he'll be in the lineup Saturday against Oakland.
