main grandstand at the team's spring training facility, which has the post-reconstruction dimensions. Outfield dimensions During its 87-year existence, Yankee Stadium's dimensions were changed several times. The many photographs taken throughout the stadium's history serve as references, especially as the Yankees were among the first to post distance markers on the outfield walls, doing so beginning in 1928. In its 1923 incarnation, the right and left field foul lines hit the box seat railings at a distance of only about 257 feet from home plate. This did not pose too much of a problem for pitchers, as the seating angled away sharply, especially in left field. The right field corner was a problem for the outfielders, as its construction tended to make a bounding fair ball take an unpredictable carom. This problem, dubbed the "bloody angle" by the players, was solved prior to the 1924 season by moving the infield some ten feet toward center and rotating it slightly. That resulted in a new left field distance of , and a new right field of (eventually posted as 295). By 1928 some of the box seats had been chiseled away in the left field corner, allowing a somewhat longer foul line distance of . The seating curved away sharply and the far corner of the lower left stand was away. The large wooden bleachers remained well out of reach to most batters hitting toward left and center fields. In 1928 the deep left-center field corner was marked as , with the deep right-center field corner 429. The "straightaway" right field distance (at an exit gate) was marked 350 and the right field foul line 295. The right field area would remain the only hitter-friendly portion of the outfield before its 1970s remodeling. When the wooden bleachers were replaced by a concrete structure in the 1930s, its left corner (now aligned with the main stand) was marked as . Deep left center shrank to a mere , behind the flagpole. As the monuments began to accumulate, the 461 sign was moved a few feet to the right. The deep right-center corner was 407, the right corner of the bleacher area was 367, and the right field line 296, with a 344 sign about halfway between them. A 457 sign was eventually added to left-center's "Death Valley", between the 402/415 pair and the 461. The 415 sign in deep left field appears
