The Chicago Cubs run of excellent pitching continued on Saturday as Ryan Dempster threw six scoreless innings in a 4-1 win over the Arizona Diamondbacks. The Cubs have allowed two runs in their last three games.
Most of the scoring was done in the fourth inning, when the Cubs expanded their lead to 3-0 with an RBI double by Darwin Barney and an RBI single by Luis Valbuena.
That was all that Dempster would need, who allowed four hits and struck out five batters in the game. He lowered his ERA to 1.86 with Saturday's performance.
Despite allowing a hit and a walk, Carlos Marmol held on for a save and gave the Cubs their 35th win of the season.
Chicago will go for the sweep on Sunday when it sends Matt Garza (4-7, 4.32 ERA) to the hill.
