''Today I felt fine,'' said the son of Hall of Fame catcher Ivan Rodriguez. Rodriguez earned his first big league win, giving up a home run to Jake Arrieta but outpitching the Phillies ace to lead the San Francisco Giants over Philadelphia 6-1 Sunday for a three-game sweep. The 25-year-old righty had pitched just once before in the majors, going 3 1/3 innings in relief last Tuesday at Colorado.
