Legacy
Ryan played in more seasons (27) than any other major league player since 1900. (He is tied with Cap Anson for the most all time.) Ryan ranks first for all-time in strikeouts (5,714), fewest hits allowed per nine innings (6.56), and no-hitters (7). He is also fifth in innings pitched (5,386), second in games started (773), seventh in shutouts (61), is tied for 14th in wins (324), and is third in losses (292).
Opposing hitters hit .204 against Ryan during his career, although they had a .309 on-base percentage against him. He also limited hitters to a .298 slugging percentage. Ryan had 15 or more strikeouts in a game 26 times, second to Randy Johnson, who had 28. Ryan's lengthy career spanned generations as he struck out seven pairs of fathers and sons (for example, Bobby Bonds and Barry Bonds), another major league record. Ryan also played during the administrations of seven U.S. Presidents—Lyndon B. Johnson, Richard M. Nixon, Gerald Ford, Jimmy Carter, Ronald Reagan, George H. W. Bush, and Bill Clinton—equaling a 20th-century record that had been set by Jim Kaat.
Ryan also ranks high on the list for four "negative" records; he ranks first all-time in walks allowed (2,795), first in wild pitches (277), third in losses (292 – most in the post-1920 live-ball era), and ninth in batters hit (158). Ryan was the first pitcher in MLB history to give up ten grand slam home runs, including one to Dann Howitt, the next-to-last batter Ryan faced in his career; that record has since been surpassed.
Bill James focused on this dichotomy between Ryan's positive and negative statistics. While ranking him as the 24th best pitcher of all time, he noted, "Ryan has been retired almost ten years [as of 2001], in another ten perhaps we will begin to get a little bit of perspective on him. Ryan's log of spectacular accomplishments is as thick as Bill Clinton's little black book; his list of flaws and failures is lengthy but dry, and will never make for good reading."
Other writers have delved more into the specifics of James' general concerns. ESPN writer Rob Neyer stated in a 2003 column that while Ryan was among the 20 best pitchers since World War II, he "often had trouble throwing strikes, [and] he wasn't any good at fielding his position". In another column, Neyer, while stating that Ryan belonged in the Hall of Fame, pointed to Ryan's record-breaking walks total and noted that his .309 on-base percentage against "wasn't even close to being in the top 100".
Ryan and Frank Robinson are the only two major league players to have their number retired by three teams on which they played. The California Angels retired the number 30 on June 16, 1992; the Texas Rangers retired his number 34 on September 15, 1996; and the Houston Astros retired number 34 on September 29, 1996. His number was the first retired by the Rangers.
Ryan was elected to the Baseball Hall of Fame in 1999 in his first year of eligibility with 98.79% of the vote (491 out of 497 possible), six votes short of a unanimous election and the sixth-highest percentage in history, behind Mariano Rivera (100%, 425 out of 425 possible), Derek Jeter (99.75%, 396 out of 397 possible), Ichiro Suzuki (99.75%, 393 out of 394 possible), Ken Griffey Jr. (99.32%, 437 out of 440 possible), and Tom Seaver (98.84%, 425 out of 430 possible). He chose to wear a Rangers cap for his HOF plaque to reflect his Texas heritage, as well as the fact that his 300th win, 5000th strikeout, and last two no-hitters came as a Ranger. He was the first Hall of Famer inducted as a Ranger. However, the Hall of Fame recognizes the Los Angeles Angels as his primary team.
In 1999, he ranked 41st on The Sporting News list of the 100 Greatest Baseball Players and was elected to the Major League Baseball All-Century Team. He was inducted into the Texas Rangers Hall of Fame in 2003, and named the Rangers', and Astros' Hometown Hero in 2006—the only player to be so named by two franchises. In 2020, The Athletic ranked Ryan at number 50 on its "Baseball 100" list, complied by sportswriter Joe Posnanski.
In 2011, he was inducted into the Irish American Baseball Hall of Fame.
In 1992, the United States Mint produced a $1 commemorative coin honoring Olympic baseball depicting a pitcher in a USA Baseball uniform in a pose nearly identical to Ryan's photo on his 1991 Fleer baseball card. The numismatic community subsequently referred to the coin as the "Nolan Ryan dollar".
In 1995 the Texas State Legislature declared State Highway 288, which passes near Alvin, as the Nolan Ryan Expressway.
The Alvin Independent School District opened Nolan Ryan Junior High School, located at 11500 Shadow Creek Parkway (FM 2234) in Pearland, Texas, just a few hundred yards away from the Nolan Ryan Expressway.
The Nolan Ryan Foundation is a Texas nonprofit organization that supports youth, education, and community development and is headquartered in Round Rock, Texas.
The Texas Trail of Fame inducted Ryan in 2009. The Texas Cowboy Hall of Fame inducted Ryan in 2010.
A documentary, Facing Nolan, was released in 2022.
