It was in May of 1990 that the Cardinals acquired one of the most dominant closers in MLB history. Lee Smith came to the Redbirds in a trade with the Boston Red Sox for Tom Brunansky on May 4. Smith would go on to have three consecutive 40-plus save seasons from 1991-94, and was the franchise's saves leader until Jason Isringhausen claimed the title in 2006. Smith collected his 300 career save in 1991 with the Cardinals (see photo), and was MLB's all-time saves leader at the time of his retirement in 1997 with 478.
Jose Oquendo cemented his standing as one of the game's ultimate utility players by playing every position on the diamond in 1988. What may be the most remarkable part of this endeavor is that he took the mound and pitched four innings of relief during a 16-inning game on May 14. Due to his versatility he was nicknamed the "Secret Weapon." Oquendo still holds the franchise record for fewest errors as a second baseman (3 in 1990) and continues to serve as the club's third base coach.
The Major League records continued to fall in 1963 as Stan Musial played his final season. On May 8, "The Man" overtook the "Babe" by breaking his Major League record for extra-base hits with 1,357 on a home run against the Dodgers. Shown here is the scorecard from that affair, which resides in the Cardinals Museum collection. It has been appropriately scored and includes an extra note regarding Musial's record-breaking round-tripper.
