Sullivan went 2-for-4 with a double, a home run and four RBI in Wednesday's 7-1 win over Cincinnati.
Sullivan was the unlikely hero in Wednesday's victory. In his fifth MLB start, the 29-year-old rookie got the Padres' offense started with a two-run double in the second inning before cranking a two-run homer off Alex Young in the fourth. In two at-bats, Sullivan recorded the first extra-base hit, home run and RBI of his major-league career. He's now 4-for-17 with a walk this season. Sullivan could see additional opportunities backing up Austin Nola behind the plate while Luis Campusano (thumb) remains sidelined.
