Embattled Yankees slugger Alex Rodriguez is apparently trying to work the charm offensive. Sports Illustrated reporter Selena Roberts, who co-wrote the story that revealed his steroid use during his Texas Rangers days, says the player called her to apologize for his remarks during his ESPN interview (A-Rod had complained, "What makes me upset is that Sports Illustrated pays this lady, Selena Roberts, to stalk me... Really respectable journalists are following this lady off the cliff and following her lead."). Rodriguez seems to be enjoying things in spite of the controversy: He went on a Valentine's date with a model last night; an onlooker told the Daily News, "They were not holding hands, but they looked very happy; he seemed very into her."
