Input: Question: What is the lifetime ERA of the pitcher that Rizzo hit his first home run against? Passage:Rizzo was called up to the majors after hitting .365 with an OPS of 1.159 along with 16 home runs and 63 RBI in 200 at-bats over 52 games in Tucson. The San Diego Union-Tribune called Rizzo "the most celebrated Padres call-up" since Roberto Alomar debuted with the team in 1988. Rizzo's promotion was prompted by the Padres' inadequate offensive production and fielding play of veterans at first base. In his debut on June 9, 2011, against the Washington Nationals, Rizzo struck out in his first at-bat, but then proceeded to hit a triple and score a run, helping the Padres to a 7–3 victory. He hit his first home run on June 11 against John Lannan. After three games he was 3-for-7 with a double, triple and a home run, while he demonstrated patience in drawing four walks for a .667 on-base percentage (OBP). On July 21, 2011 Rizzo was demoted back to Triple-A, and Blanks was promoted. Rizzo had struggled with only a .143 batting average and 1 home run, striking out 36 times in 98 at-bats. Hoyer said Rizzo "worked hard, never made excuses, and endeared himself to his teammates" during his initial stint in the majors. Rizzo was recalled to the majors on September 4 after finishing the season at Tucson batting .331 with 26 homers and 101 RBI in 93 games. He finished his first season in San Diego hitting only .141 with 46 strikeouts in 128 at-bats. Hoyer believed Rizzo would be the starting first baseman for the Padres in 2012 with Jesús Guzmán as the second option. However, Yonder Alonso moved ahead of Rizzo on the team's depth chart after he was acquired by the Padres in December 2011 in a trade for Mat Latos.
