Brett Myers makes his job sound so easy: Throw the ball, let the other team hit it at his fielders.Myers did more than that Wednesday night, striking out eight in seven crisp innings as the Houston Astros beat the listless Cubs 4-0.Myers has lasted at least six innings in all 29 of his starts — the longest streak in team history and longest in the majors since Curt Schilling’s run of 35 straight for Arizona in 2002. He also dropped his ERA to 2.91.Myers (11-7) allowed three hits and walked one, improving to 10-3 with a 2.21 ERA in 17 career games against the Cubs. The right-hander is 3-0 with a 1.76 ERA in his last six starts overall.Surging Houston, which won for the 13th time in 17 games, took all five series against the Cubs this season.”Their lineup has changed a lot, without Derrek Lee and without [Aramis] Ramirez,” Myers said. Randy Wells (6-13) allowed four runs and nine hits in six innings for the Cubs.Myers retired the first 14 batters he faced. He got some help from his defense when second baseman Jeff Keppinger made a backhanded stop and a leaping throw to get Starlin Castro in the fourth inning.Geovany Soto walked with two outs in the fifth for the Cubs first baserunner and Alfonso Soriano followed with a single. But Myers got Darwin Barney to ground out to end the threat. Myers also worked out of a jam in the seventh, retiring two straight after the Cubs put runners on the corners with one out. He is 3-0 with a 1.21 ERA in four starts against the Northsiders this year.Fernando Abad, Matt Lindstrom, Tim Byrdak and Wilton Lopez combined to finish the five-hitter, Houston’s ninth shutout of the season.The Cubs finished a nine-game homestand with a 5-4 record and lost back-to-back games under Mike Quade for the first time. Quade took over when manager Lou Piniella retired on Aug. 23.The Cubs were shut out for the 10th time this season.Quintero hit an RBI single in the second and Hunter Pence connected in the third for his 23rd homer. Chris Johnson added an RBI single in the fifth and Keppinger drove in a run with a groundout in the sixth.After being benched the previous two games by Quade, Castro committed an error on Lee’s grounder to shortstop in the first inning. Quade sat Castro for his poor defensive play and not knowing how many outs there were during the seventh inning of Chicago’s 18-5 loss to the Mets on Sunday.

NOTES—Ramirez missed his third straight game with a sore right quad. He is day-to-day.
