LAKE BUENA VISTA, Fla. -- It's not entirely fair to say the Dodgers left the winter meetings without adding to their roster. In a trade with the New York Mets Thursday, they landed Seth Rosin, a 6-foot-6 24-year-old right-handed pitcher who had a 4.33 ERA at Double-A last season. The Mets had just taken Rosin in the Rule 5 draft from the Philadelphia Phillies, who had left him off their 40-man roster.Not exactly the name Dodgers fans were hoping for, perhaps?
