After hitting .395 for the Cubs in nine games that year, he batted .254 for the team in 1917, finishing fourth in the league with 6 home runs, before a pair of January 1918 trades brought him back to New York. He hit .261 in his return to the Giants before having his last outstanding season in 1919; that year he again was league runnerup in slugging with a .433 average, and was fifth in home runs (7). He batted .285 in his final season in , and was granted his release so he could manage the Toronto Maple Leafs of the International League. At the time, he was within five games of Johnny Evers' league record for career games at second base. Doyle ended his career with a .290 batting average, putting him behind only Nap Lajoie (.338), Eddie Collins (then at .329) and Cupid Childs (.306) among players with 1000 games at second base. His 74 home runs placed him third at his position behind Fred Pfeffer (94) and Lajoie (83). He also had 960 runs and 794 RBI in 1766 games, as well as 298 stolen bases including 17 steals of home plate; he held the Giants club record for career steals from 1918 to 1919, when teammate George Burns passed him. "Baseball Magazine" selected Doyle as the second baseman on their NL All-America Team in 1911 and 1915. Doyle contracted tuberculosis in 1942, and entered the Trudeau Sanitorium in Saranac Lake, New York. When the institution closed in 1954 due to the development of an effective antibiotic treatment, he was the last resident to leave; "Life Magazine" photographers covered his last meal and his departure, on foot, from the grounds. He stayed on in Saranac Lake, and died there 20 years later, at age 87.
