After a decade of success with the Cubs, Kling was traded to the lowly Boston Braves, where he spent the 1911 and 1912 seasons. At one point he even managed the Braves, but his managerial efforts were not successful and the team had a losing record He was said to be unhappy with the way the Braves' owners made him run the team, and this led to his being traded in 1913. His final year in the majors was spent with the Cincinnati Reds. He devoted the rest of his life to several important pursuits. He owned the Dixon Hotel in Kansas City, where his billiard parlor gained national recognition. During his baseball career, he had begun mentoring his nephew, Bennie Allen, and as the years passed, Bennie went on to become a champion too. In 1933, he purchased the Kansas City Blues of the American Association and was able to generate more interest in the team and increase their attendance within a year of taking over. One of his innovations was to desegregate the ballpark, allowing both black and white fans to attend the games together. Kling sold the Blues in 1937.
