Compared with the present, professional baseball in the early 20th century was lower-scoring, and pitchers, including stars Walter Johnson and Christy Mathewson , were more dominant. The " inside game ", which demanded that players "scratch for runs", was played much more aggressively than it is today: the brilliant and often violent Ty Cobb epitomized this style.  The so-called dead-ball era ended in the early 1920s with several changes in rule and circumstance that were advantageous to hitters. Strict new regulations governing the ball's size, shape and composition, along with a new rule officially banning the spitball and other pitches that depended on the ball being treated or roughed-up with foreign substances, followed the death of Ray Chapman after a pitch struck him in the head in August 1920. Coupled with superior materials available after World War I, this resulted in a ball that traveled farther when hit. The construction of additional seating to accommodate the rising popularity of the game often had the effect of reducing the distance to the outfield fences, making home runs more common.  The rise of the legendary player Babe Ruth , the first great power hitter of the new era, helped permanently alter the nature of the game. The club with which Ruth set most of his slugging records, the New York Yankees , built a reputation as the majors' premier team.  In the late 1920s and early 1930s, St. Louis Cardinals general manager Branch Rickey invested in several minor league clubs and developed the first modern " farm system ".  A new Negro National League was organized in 1933; four years later, it was joined by the Negro American League . The first elections to the National Baseball Hall of Fame took place in 1936. In 1939 Little League Baseball was founded in Pennsylvania. By the late 1940s, it was the organizing body for children's baseball leagues across the United States. 
Below is a list of the first black players in Major League Baseball in chronological order, since the abolition of the Baseball color line . During the 1880s, Moses Fleetwood Walker , a black man, had played for the Toledo Blue Stockings of the American Association (his brother Welday Walker also played a few games with the club), and it was essentially against Fleetwood Walker that the line was originally drawn. African-Americans had been excluded from major league baseball since 1884, and from all of professional baseball since 1889.
“Bruce’s father is a proud military lifer,” Maxwell’s agent, Matt Sosnick, said via text. “Anyone who knows Bruce or his parents is well aware that the Maxwells’ love and appreciation for our country is indisputable. Bruce has made it clear that he is taking a stand about what he perceives as racial injustices in this country, and his personal disappointment with President Trump’s response to a number of professional athletes’ totally peaceful, nonviolent protests. Bruce has shared with both me and his teammates that his feelings have nothing to do with a lack of patriotism or a hatred of any man, but rather everything to do with equality for men, women and children regardless of race or religion.”
