Shibe Park, known later as Connie Mack Stadium, was a baseball park located in Philadelphia. It was the home of the Philadelphia Athletics of the American League (AL) and the Philadelphia Phillies (also known as the Blue Jays from 1944 to 1949) of the National League (NL). When it opened April 12, 1909, it became baseball's first steel-and-concrete stadium. In different eras it was home to "The $100,000 Infield", "The Whiz Kids", and "The 1964 Phold". The venue's two home teams won both the first and last games at the stadium: the Athletics beat the Boston Red Sox 8–1 on opening day 1909, while the Phillies beat the Montreal Expos 2–1 on October 1, 1970, in the park's final contest.
