Christian Walker hit a three-run double in the eighth inning and the Arizona Diamondbacks broke out of their offensive funk to rally past the Los Angeles Dodgers 5-3 Friday night. ''I know what this team has been going through and how hard they've been playing, so come through and be there for my teammates meant a lot to me,'' Walker said. Trailing 3-2 in the eighth, Arizona loaded the bases against Blake Treinen (0-1) and Walker lined a double just past the outreached glove of center fielder Mookie Betts.
