Lynn (5-1) was credited with the win Monday after allowing one run on three hits and three walks while striking out four over seven innings against the Cardinals.
Lynn was locked in a pitchers' duel with St. Louis lefty Kwang Hyun Kim before earning a victory over the team that drafted him in the first round in 2008. He carried a no-hitter into the sixth inning, when the Cards managed to push a run across, but Chicago's offense eventually showed up, giving Lynn a win in his fourth straight decision. Lynn's next turn in the rotation comes Saturday at home against the Orioles.
