After hitting in either the second or eighth spot in the batting order for most of his time in St. Louis, Herzog made Smith the number-two hitter full-time during the 1987 season. Over the course of the year, Smith accrued a .303 batting average, 43 stolen bases, 75 RBIs, 104 runs scored, and 40 doubles, good enough to earn him the Silver Slugger Award at shortstop. In addition to winning the Gold Glove Award at shortstop for the eighth consecutive time, Smith posted a career-high on-base percentage of .392. Smith was also the leading vote-getter in the 1987 All-Star Game. The Cardinals earned a postseason berth with 95 wins, and subsequently faced the San Francisco Giants in the 1987 National League Championship Series. Smith contributed a triple during the series, and the Cardinals won the contest in seven games.
