There are celebrated milestones in baseball for hitters – 3,000 hits and 500 home runs. For pitchers, 300 wins is not only a culmination of great pitching, but also longevity. Every pitcher with 300 wins, with the exception of Roger Clemens, has earned a spot in the Hall of Fame. Only 24 pitchers have ever reached 300-win threshold and with the increase in the use relievers and starting pitchers throwing less innings, this may be the only 24 pitchers in this exclusive club for years to come.

Hall of Famer Steve Carlton, one of the most dominating left-handers in baseball history, reached his 300-win milestone on September 23rd, 1983 when he defeated his former team, the St. Louis Cardinals, pitching eight innings, allowing only two earned runs on seven hits, while striking out 12 in the victory.

This all-maroon cap was worn by Carlton during his historic and milestone 300th career win. This cap was manufactured by Wilson and is a size 7 1/8. The Philadelphia “P” is embroidered in white on the front. The green underside brim has Carlton’s number “32” handwritten in black marker. Please note that the top halves of the numbers have faded. The cap displays moderate game use with dirt and sweat stains present on the white inner head band. Carlton has signed this cap in black marker below his number on the underside brim and inscribed “#300” and “9/22/83”. Please note that due to poor handwriting, the “83” in the date may look like 82. This cap comes with a photocopy of a COA from Steve Carlton signed to "Barry" as part of the Barry Halper Collection from Sotheby's 1999 Auction authenticating the use of this cap for his 300th win.
