Walker hit .278 with 6 home runs, 78
runs batted in (RBI) and a career-high 29 stolen bases in 151 games during the 1914 season. His offensive totals dropped with the 1915 Browns; he finished with a .269 average, 5 home runs, 49 RBI and 20 steals. Just before the 1916 season, the
Boston Red Sox purchased Walker's contract for US$3,500 ($ today). Walker was seen as a good hitter and he had a strong arm, having led the league's outfielders in assists for the two previous seasons. However, he had been criticized for his mood swings and for not being a team player. Walker earned one of his lowest batting averages (.266) that year, but Boston won the
1916 World Series. In that series, he batted twelve times and earned three hits, including a
triple. He played only 106 games in 1917, hitting a career-low .246 for the Red Sox. Before the 1918 season, Walker was sent to the
Philadelphia Athletics as the
player to be named later in a multiplayer trade for first baseman
Stuffy McInnis. He tied Ruth as the league leader in homeruns (11) in 1918. ==Later career==
