Nolan Ryan, a hard-throwing, right-handed pitcher, threw pitches that were regularly recorded above 100 miles per hour. The high velocity remained throughout his career, even into his 40s. Ryan was also known to throw a devastating 12–6 curveball at exceptional velocity for a breaking ball. Ryan is the all-time leader in no-hitters with seven, three more than any other pitcher. He is tied with Bob Feller for most one-hitters, with 12. Ryan also pitched 18 two-hitters. He was inducted into the Baseball Hall of Fame in 1999.

This New Era official California Angels cap was signed in silver by Ryan and includes a Great Moments COA.
