The Red Sox began 1967 playing better baseball and employing the aggressive style of play that Williams had learned with the Dodgers. Williams benched players for lack of effort and poor performance, and battled tooth and nail with umpires. Through the All-Star break, Boston fulfilled Williams' promise and played better than .500 ball, hanging close to the American League's four contending teams — the Detroit Tigers, Minnesota Twins, Chicago White Sox and California Angels. Outfielder Carl Yastrzemski, in his seventh season with the Red Sox, transformed his hitting style to become a pull-hitter, eventually winning the 1967 AL Triple Crown, leading the league in batting average, home runs (tying Harmon Killebrew of the Twins), and RBI.
