LOS ANGELES – Shadows creep across the Dodger Stadium infield by the end of day games, which means they will be a factor for the first several innings of the National League Division series that gets underway Friday at 3:37 p.m. PT.The start time, announced Monday, could make it hard for hitters to pick up the spin on pitches and the two pitchers scheduled to start, Clayton Kershaw of the Los Angeles Dodgers and Adam Wainwright of the St. Louis Cardinals, happen to throw some of the best breaking balls in baseball.
