Yasmani Grandal threw out a runner at the plate after an errant pitch in the top of the 13th inning, then homered leading off the bottom half to lead the Los Angeles Dodgers over the Arizona Diamondbacks 1-0 on Sunday for their fourth straight win. Arizona had runners at the corners with two outs in the 13th when J.P. Howell (1-1) bounced a pitch to Cliff Pennington that Grandal had to chase to the right of home plate. Grandal threw to Howell covering the plate, and the pitcher reached down behind with his glove to make a blind tag on Aaron Hill. Grandal drove a 1-1 pitch from Evan Marshall (0-2) into the pavilion seats in left-center for his second homer since the Dodgers acquired him from San Diego in the Matt Kemp trade.
