After one of his finest performances for the Chicago Cubs, Jon Lester will try to keep his momentum going by adding to his mastery of the Philadelphia Phillies. The left-hander earned his latest win over Philadelphia less than two weeks ago and will seek to improve to 6-0 in eight career matchups in Monday night's series opener at Citizens Bank Park. Lester (6-3, 2.29 ERA) pitched a four-hitter with 10 strikeouts and went the distance for the first time this season in Wednesday's 2-1 victory over the Los Angeles Dodgers.
