SAN DIEGO -- Randall Delgado's plan was to start Justin Upton off with a fastball to get ahead, and then finish him off with his breaking ball or changeup.
Delgado never got past that first pitch. Upton smashed the first-pitch fastball into the left-field bleachers for a eighth-inning home run that led the Padres past the D-backs, 3-2, on Wednesday night at Petco Park.
"He's a great hitter, and [Delgado] made a bad pitch, and that's what happens," said D-backs manager Chip Hale.
The D-backs drafted Upton No. 1 overall in 2005 and traded him to the Braves prior to the 2013 season.
