The regular season is barely one-third complete, but it's not too early to wonder if this weekend's series between the Philadelphia Phillies and Los Angeles Dodgers is a potential playoff preview. The top two teams in the National League will face off Friday in the opener of a three-game series when the Dodgers host the Phillies. Right-hander Kenta Maeda (6-2, 3.67 ERA) is scheduled to take the mound for Los Angeles against Philadelphia right-hander Jake Arrieta (5-4, 3.60).
