Matt Kemp hit an RBI single in the 10th inning, giving the Los Angeles Dodgers a 1-0 victory over the Houston Astros on Friday night. Casey Blake led off the 10th against David Carpenter (0-2) with a double inside first base, and Andre Ethier was intentionally walked before Kemp slapped an 0-2 pitch the other way just inside the right field line for his fifth career walkoff hit.
