Edwin Jackson held San Francisco hitless until Conor Gillaspie's three-run homer with one out in the seventh inning, and the San Diego Padres held off the Giants 5-3 Sunday for their first sweep of the season. Jackson, making his first start since 2014, and three relievers combined on a two-hitter against the Giants, who despite losing three straight still have the best record in the majors at 57-36. San Diego remains the only big league team without a no-hitter, having played 7,582 games without one since starting out in 1969.
