The Athletics and their new stadium were a hit: the A's won pennants – and brought World Series to town – in 1910 and 1911, and by 1913, when they would win another, Shibe initiated the first of the expansions of seating capacity that would continue right on through the 1950s. He called again upon the Steele company and added a new unroofed bleacher section across left field, taking advantage of the site's rectangular, rather than square, shape, and also added roof structures to cover the open pavilions down the first base and third base lines.
