The last time Vin Scully threw out a ceremonial first pitch, the Dodgers had someone (Orlando Hudson) hit for the cycle. Los Angeles looks for more Scully magic on his bobblehead night as they open a four-game weekend series against the Diamondbacks at Dodger Stadium. Perhaps that magic can be created by Clayton Kershaw, who starts the opener in search of his 13th win of the season. In four of his six career starts at home against Arizona Kershaw has allowed zero runs, including each of the last three. Kershaw has a personal 19-inning scoreless streak at Dodger Stadium against the Diamondbacks, dating back to last season, with five walks and 22 strikeouts during that span.
