The statue is outside of Busch Stadium that was created by Harry Weber.
In the eight seasons from 1963 to 1970, he won 156 games and lost 81, for a .658 winning percentage. He won nine Gold Glove Awards, was awarded the World Series MVP Award in 1964 and 1967, and won Cy Young Awards in 1968 and 1970.
In Game 7 of St. Louis's World Series triumph on October 15, 1964, Gibson held on to earn the win despite allowing ninth-inning home runs to New York Yankees Phil Linz and Clete Boyer (brother of the Cardinals' Ken Boyer).
In 1967, Gibson made a remarkable recovery from a broken leg to become the premiere pitcher in that year's World Series. Gibson's normal follow-through included landing hard on his right leg. On July 15, he was hit by a line drive off the bat of Roberto Clemente just at that point of his follow through. The broken leg put Gibson on the disabled list until early September, while the Cardinals continued to play well. With Gibson back in the lineup, the Cardinals secured the National League pennant.
In the 1967 Series, Gibson allowed only three earned runs and 14 hits over three complete game victories (Games 1, 4, and 7), the latter two marks tying Christy Mathewson's 1905 record, also hitting a vital home run in Game 7.
The 1968 season became known as "The Year of the Pitcher", and Gibson was at the forefront of pitching dominance. His earned run average was 1.12, which is a live-ball era record, the major league record in 300 or more innings pitched and was the lowest major league ERA in 54 years (see Dutch Leonard). He threw 13 shutouts, behind only Grover Alexander's 1916 Major League record of 16, and allowed only two earned runs in 92 straight innings of pitching. Gibson also pitched 47 consecutive scoreless innings, at the time the third longest scoreless streak in Major League history only to Walter Johnson's 56 in 1913, and Don Drysdale's 58 2/3 (set earlier in that same season). He also won the National League MVP. With the batting anemic everywhere, Gibson lost 9 games against 22 wins despite his record-setting low ERA.
In Game One of the 1968 World Series, he struck out 17 Detroit Tigers to set a World Series record for strikeouts in one game (breaking Sandy Koufax's record of 15 in Game One of the 1963 World Series), which still stands today.
Gibson's 1968 season was so successful that his performance is widely cited in Major League Baseball's decision to lower the pitcher's mound by five inches in 1969. The change had only a slight effect on him; he went 20-13 that year, with a 2.18 ERA. Some say that his 13 shutouts may never be repeated by anyone again given the heavier emphasis on pitch counts, relief pitching, and the continuing shift to hitters with newer ballparks having smaller foul areas, shorter distance to the outfield walls, and a smaller strike zone today.
On May 12, 1969, Gibson struck out three batters on nine pitches in the seventh inning of a 6-2 win over the Los Angeles Dodgers. Gibson became the ninth National League pitcher and the 15th pitcher in Major League history to accomplish the nine-strike/three-strikeout half-inning.
Gibson achieved two highlights in August 1971. On the 4th of the month, he defeated the San Francisco Giants 7-2 at Busch Stadium for his 200th career victory. Ten days later, he no-hit the Pittsburgh Pirates 11-0 at Three Rivers Stadium. Three of his 10 strikeouts in the game were to Willie Stargell, including the game's final out. The no-hitter was the first in Pittsburgh in more than 60 years; none had been pitched in the 62-year (mid-1909 to mid-1970) history of Three Rivers Stadium's predecessor, Forbes Field.
He was the second pitcher in MLB history (after Walter Johnson) to strike out over 3,000 batters, and the first to do so in the National League. He accomplished this at home, at Busch Stadium on July 17, 1974, the victim being César Gerónimo of the Cincinnati Reds.  (Gerónimo would also become Nolan Ryan's 3,000th strikeout victim, in 1980.)
Gibson was also a good hitting pitcher and was sometimes used by the Cardinals as a pinch-hitter. In 1970, he hit .303 for the season, which was over 100 points higher than his teammate, shortstop Dal Maxvill. For his career, he batted .206 with 24 home runs (plus two more in the World Series) and 144 RBIs. He is one of only two pitchers since World War II with a career batting average of .200 or higher and with at least 20 home runs and 100 RBIs (Bob Lemon, who had broken into the majors as a third baseman, is the other).
Gibson was above average as a baserunner and thus was occasionally used as a pinch runner, despite managers' general reluctance to risk injury to pitchers in this way.
The constant pounding on Gibson's right knee took its toll, eventually inflicting knee injuries that contributed to Gibson losing his effectiveness. In his final season, he went 3-10 and announced his retirement.
