On this day in 2011, the run-starved Padres called up their top offensive prospect, first baseman Anthony Rizzo, who immediately made his presence known in his big league debut that night. Rizzo, who was acquired the previous December from the Red Sox along with pitching prospect Casey Kelly, outfield prospect Reymond Fuentes, and fringe utility man Eric Patterson in the trade that sent Adrian Gonzalez to Boston, was hitting .365/ .444/ .715 with 16 home runs and a Pacific Coast League-leading 63 RBI for the Padres' AAA affiliate in Tucson at the time of his promotion.
Rizzo was placed in the starting lineup that night, and struck out in his first trip to the plate.
