As part of a dominant starting rotation for the Braves in the 1990s that included Greg Maddux and Tom Glavine, Smoltz helped make Atlanta perennial contenders, highlighted by a championship in the 1995 World Series. Though predominantly known as a starting pitcher, Smoltz was converted to a reliever in 2001, following his recovery from Tommy John surgery, and he spent four years as the team's closer before returning to a starting role. In 2002, he became only the second pitcher in history to record a 20-win season and a 50-save season (the other being Dennis Eckersley). He is the only pitcher in major league history to top both 200 wins and 150 saves. In 2008, he became the 16th member of the 3,000 strikeout club.

This Rawlings official 1995 World Series baseball was signed in blue ballpoint pen by Smoltz and includes a Great Moments COA.
