Rickey Nelson Henley Henderson (born December 25, 1958) is an American retired professional baseball left fielder who played his 24 seasons in Major League Baseball (MLB) for nine teams from 1979 to 2003, including four separate tenures with his original team, the Oakland Athletics. Nicknamed the "Man of Steal", he is widely regarded as baseball's greatest leadoff hitter and baserunner. He holds the major league records for career stolen bases, runs, unintentional walks and leadoff home runs. At the time of his last major league game in 2003, the ten-time American League (AL) All-Star ranked among the sport's top 100 all-time home run hitters and was its all-time leader in walks. In 2009, he was inducted to the Baseball Hall of Fame on his first ballot appearance.

Henderson holds the single-season record for stolen bases (130 in 1982) and is the only player in AL history to steal 100 bases in a season, having done so three times. His 1,406 career steals is 50% higher than the previous record of 938 by Lou Brock. Henderson is the all-time stolen base leader for the Oakland Athletics and previously held the New York Yankees' franchise record from 1988 to 2011. He was among the league's top ten base stealers in 21 different seasons.

Henderson was named the AL's Most Valuable Player in 1990, and he was the lead-off hitter for two World Series champions: the 1989 Oakland Athletics and the 1993 Toronto Blue Jays. A 12-time stolen base champion, Henderson led the league in runs five times. His 25-year career elevated Henderson to the top ten in several other categories, including career at-bats, games, and outfield putouts and total chances. His high on-base percentage, power hitting, and stolen base and run totals made him one of the most dynamic players of his era. He was further known for his unquenchable passion for playing baseball and a buoyant, eccentric, and quotable personality that both perplexed and entertained fans. Once asked if he thought Henderson was a future Hall of Famer, statistician Bill James replied, "If you could split him in two, you'd have two Hall of Famers."

Lynn Nolan Ryan Jr. (born January 31, 1947), nicknamed The Ryan Express, is an American former Major League Baseball (MLB) pitcher and sports executive. Over a record 27-year career that included play in four decades, Ryan pitched for the New York Mets, California Angels, Houston Astros, and Texas Rangers. He was inducted into the Baseball Hall of Fame in 1999. After his retirement in 1993, Ryan served as chief executive officer (CEO) of the Texas Rangers and an executive advisor to the Houston Astros. He is widely considered to be one of the best Major League Baseball (MLB) pitchers of all time.

Ryan was a right-handed pitcher who consistently threw pitches that were clocked above 100 miles per hour (161 km/h). He maintained this velocity throughout his pitching career. Ryan was also known to throw a devastating 12–6 curveball at exceptional velocity for a breaking ball.Ryan had a lifetime record of 324–292 (.526) and was an eight-time MLB All-Star. His 5,714 career strikeouts is an MLB record by a significant margin. He leads the runner-up, Randy Johnson, by 839 strikeouts. Similarly, Ryan's 2,795 bases on balls lead second-place Steve Carlton by 962 – walking over 50% more hitters than any other pitcher in MLB history. Ryan's lifetime batting average allowed of .204 is also a major league record. Ryan, Pedro Martínez, Randy Johnson, Trevor Hoffman, and Sandy Koufax are the only five pitchers inducted into the Baseball Hall of Fame who had more strikeouts than innings pitched. Ryan is one of only three players in history to have his number retired by at least three teams, along with Jackie Robinson (whose number was retired by Major League Baseball) and Frank Robinson.

Ryan is the all-time leader in no-hitters with seven, three more than any other pitcher. He is tied with Bob Feller for the most one-hitters, with 12. Ryan also pitched 18 two-hitters. Despite this, he never pitched a perfect game, nor did he ever win a Cy Young Award. Ryan is one of only 29 players in baseball history to have appeared in Major League baseball games in four different decades.
