In the
1961 and
1962 seasons, McAuliffe shifted between
shortstop and
second base before replacing
Chico Fernandez as the Tigers starting shortstop from
1963–
1966. Known for his wide-open batting stance and leg kick, In 1966, he finished the season ranked fourth in the league with a .373
on-base percentage and fifth with a .509
slugging percentage. After making the American League All-Star team again in 1966 at shortstop, McAuliffe agreed to move to second base in
1967 to make room for
Ray Oyler to take over at shortstop. Even with the move, McAuliffe was selected for his third consecutive All-Star team in 1967. The 1967 season was memorable for the tight four-way pennant race between the Tigers,
Boston Red Sox,
Minnesota Twins, and
Chicago White Sox, with all four teams still in contention entering the final week of the season. The Tigers needed to win the final game of the season against the
California Angels, to force a one-game playoff with the Red Sox for the American League championship. However, the Tigers lost, finishing one game behind the Red Sox. Along with
Al Kaline and
Bill Freehan, McAuliffe played an integral role for the Tigers during the 1967 season, finishing among the American League leaders in
walks with 105 (3rd), 245 times on base (3rd), 7 triples (3rd), 92 runs (5th), 118
strikeouts (5th), 22 home runs (8th), and a .364 on-base percentage (9th). McAuliffe played a key role in the
Tigers' 1968 World Championship season. He had a .344 on-base percentage, led the American League with 95
runs scored, and showed power with 50 extra base hits. He also tied a
major league record by going the entire 1968 season without grounding into a
double play and was the first American League player to do so. McAuliffe also improved defensively in 1968, reducing his
error total from 28 in 1967 to 9 in 1968 and finished second among American League second basemen in
fielding percentage. He finished seventh in the American League
Most Valuable Player Award voting, behind teammates
Denny McLain (1st),
Bill Freehan (2nd), and
Willie Horton (4th). On August 22, McAuliffe was involved in a brawl with
Chicago White Sox pitcher
Tommy John. After one pitch barely missed McAuliffe's head and another was thrown behind him, McAuliffe
charged the mound, drove his knee into John's shoulder and separated it. In the
1968 World Series, McAuliffe played all seven games at second base, scored 5 runs, and 6 hits, 4 walks, 3 runs batted in, and one home run. His steadying influence in the middle infield helped make it possible for manager
Mayo Smith to take the radical step of playing center fielder
Mickey Stanley at shortstop in the World Series in order to get a better bat in the lineup against the
St. Louis Cardinals, led by
Bob Gibson. McAuliffe continued as the Tigers' starting second baseman through the
1973 season. ==Boston Red Sox==
