Question: Which of the teams that Brock Pemberton played for has won more World Series? Passage:Brock Pemberton (November 6, 1953 – February 17, 2016) was a Major League Baseball player, who played for the New York Mets in 1974 and 1975. He also played in the St. Louis Cardinals' organization. He played as a first baseman. Pemberton played high school baseball in Huntington Beach, California and was drafted by the Mets in the 6th round of the 1972 June Amateur Draft. After playing in the lower minor leagues in 1972 and 1973, he was promoted to AA level with the Victoria Toros of the Texas League in 1974. That year, he posted a .322 batting average in 134 games and 482 at bats for the Toros. He also had 8 home runs. This performance earned Pemberton a promotion to the Major League Mets late in the season. Pemberton made his debut with the Mets as a pinch hitter on September 10, 1974, against the Montreal Expos. The next day, the Mets and St. Louis Cardinals played a 25 inning game in which Pemberton got his first Major League hit, also as a pinch hitter. In all, he played 11 games for the Mets in 1974, with 4 hits in 22 at-bats and one run batted in. In four games as a first baseman he did not make an error.
