be used more and more often. The New York Times writeup about Cy Young's no-hitter of June 30, 1908, referred to the club exclusively as "Yankees" or "Yanks" throughout the article, with no mention at all of "Highlanders". The Times also consistently referred to the Hilltop by its formal name, "the American League Park". (The Complete Book of Baseball: A New York Times Scrapbook History, Arno Press, Bobbs-Merrill, 1980, p. 8) The Philadelphia Inquirer for a game of April 21, 1912, an exhibition between the two New York clubs, was headlined "Giants wallop Yanks", while in the article the teams were referred to as the "Nationals" and the "Giants"; and "the American League team", "Americans", and "Highlanders"; respectively. The New York Times for opening day 1912 reported that "The Yankees presented a natty appearance in their new uniforms of white with black pin stripes." In 1913, the American Leaguers left the Hilltop after ten years, and began what would become a ten-year sub-lease with the Giants at the Polo Grounds. At that point the term "Highlanders" made no logical sense, and was dropped by the press. The club was exclusively the "Yankees" from then onward. It is uncertain exactly when the Yankees began referring to themselves by their popular nickname. By the time of Babe Ruth's arrival in 1920, the "Yankees" nickname was well established, but the name still did not appear on the uniforms. In fact, the Yankees have seldom carried their nickname on their uniforms. The only time was during 1927–1930, when the word "YANKEES" first appeared, in lieu of "NEW YORK" – on the road shirts. This was continued through the 1930 season, and then "NEW YORK" was restored to the road uniforms. (Okkonen) The name must have been considered 'official' at least by 1923, when the team named its new ballpark Yankee Stadium. The popular and successful Yankees have acquired many other unofficial nicknames through the years, such as the "Pinstripers" for obvious reasons, and jokingly as the "Evil Empire", a term originally applied to the Soviet Union by President Ronald Reagan. Probably the longest-lasting unofficial nickname has been the "Bronx Bombers", which was applied many decades ago in reference to the Yankees' power hitting, dating back to the Ruth era. One early newspaper usage came in July 1928. Oakland The Pacific Coast League entry was typically called the Oakland Oaks (PCL) and sometimes the Acorns
