installment of billboards in dead center. At this time, the jury box bleachers in left-center field were removed, adding to the new claustrophobic feel of the outfield. With gambling becoming an increasing problem in baseball, starting in 1911 the playing field was adorned with large signs (as with some other major league ballparks) reminding both fans and players, "No Betting Allowed." Additionally, the dilapidated park found itself competing unsuccessfully with new steel-and-concrete baseball venues. The Chicago White Sox inaugurated Comiskey Park in 1910. Four years later, the upstart Federal League placed a franchise on the North Side and began play in Weeghman Park. By 1915, the Cubs were the third most popular team in a three-team city. When the Federal League collapsed after the 1915 season, Charles Weeghman, owner of the now-defunct Chicago Whales, was allowed to buy a substantial interest in the Cubs. One of his first acts was to abandon West Side Park and move the Cubs to Weeghman Park for the 1916 season. Weeghman Park survives today as Wrigley Field. One of the few items the Cubs took with them, besides normal operational properties, was a set of large letters comprising a sign that had run across the back of the grandstand and was to be read from the outside of the park: "". This sign was placed along the top of the Weeghman Park wall bordering Sheffield Avenue, visible to everyone in the park, and of course reading backwards to the spectators. This oddity lasted a few years at Weeghman / Cubs Park until it was brought down during an early remodeling. West Side Park continued to host semipro and amateur baseball events for a few years. It even served as a setting for Buffalo Bill's Wild West, thus converting the entire former ballfield into a different kind of "bull pen". The ballpark was torn down in 1920. Murphy, who still owned the property, sold the leftover lumber for scrap. He sold the property itself to the University of Illinois. The site is now occupied by the University of Illinois Medical Center. This West Side Park was the only park that witnessed the Cubs as World Series Champions from 1908 to 2016. The Cubs won back-to-back titles here in 1907 and 1908. In June 1909, a flag-raising ceremony was held, celebrating the Cubs second consecutive World Series.
