Wandy Rodriguez has had a great start for the Houston Astros. Unfortunately, errors and a lack of run support kept the left-hander winless through his first three starts. On Sunday it all came together for Rodriguez. Jordan Schafer hit his first career grand slam on a shot that bounced off the glove of Dodgers right fielder Andre Ethier, and the left-hander pitched three-hit ball through seven innings as the Astros romped past Los Angeles 12-0. The Astros avoided a sweep and handed the Dodgers their most-lopsided shutout loss since a 13-0 defeat by the Angels in June 2004. It's the largest shutout win for Houston since beating Colorado by the same score in July 2007, a game where Rodriguez also allowed three hits in seven innings. Rodriguez (1-2) struck out six and walked three to lower his ERA to 1.42. Fernando Rodriguez and Brandon Lyon pitched an inning each to complete the shutout, which was the first of the year for Los Angeles. The Astros committed four errors in each of Rodriguez's first two starts and were shut out in his last outing, a 1-0 loss to Washington. “I feel good because last time I threw a good game but I didn't win,” Rodriguez said. “Today I threw a good game and I won, so I feel very good.” Carlos Lee got things going for the Astros with a two-run homer in the first inning. Schafer's slam came an inning later and was just the second grand slam Chad Billingsley (2-1) has allowed in his seven-year career and the first since 2008. “Wandy threw a great game today,” Lee said. “We probably only needed one (run). He continues to pitch great and keep us in the games.” D-backs 6, Braves 4: Gerardo Parra hit his first career grand slam to cap a five-run second inning and the Arizona Diamondbacks beat Atlanta, snapping a five-game losing streak. Cardinals 5, Pirates 1: Kyle Lohse scattered six hits while pitching into the eighth inning to lead the St. Louis Cardinals past Pittsburgh. Rockies 4, Brewers 1: Michael Cuddyer lined a two-run double in the eighth and Jeremy Guthrie pitched seven strong innings, leading the Colorado Rockies over Milwaukee. Reds 4, Cubs 3: Johnny Cueto threw 61/3 strong innings to lead the Cincinnati Reds past Chicago. Cueto (2-0) allowed one earned run, scattering five hits. He struck out seven and lowered his ERA to 1.78. Padres 6, Phillies 1: Nick Hundley homered, tripled and drove in a career-high four runs, leading Anthony Bass and the San Diego Padres past Philadelphia. The games San Francisco at NY Mets and Miami at Washington were postponed.
