Spahn's first full season as a starting pitcher came in 1947, when he led the National League in ERA (2.33), shutouts (7), and innings pitched () while posting a 21–10 record. In 1951, Spahn allowed the first career hit to
Willie Mays, a home run. Mays had begun his career 0-for-12, and Spahn responded to reporters after the game, citing the distance between home plate and the pitcher's mound of , "Gentlemen, for the first 60 feet, that was a hell of a pitch." Spahn joked a long time later, "I'll never forgive myself. We might have gotten rid of Willie forever if I'd only struck him out." (In 1962, another Hall of Famer hit his first career home run off Spahn:
Sandy Koufax, who only hit one other.)
"Pray for rain" Spahn's teammate
Johnny Sain was the ace of the pennant-winning 1948 Braves staff, with a win–loss record of 24–15. Spahn went 15–12, while contrary to legend, teammates
Bill Voiselle (13–13), and
Vern Bickford (11–5) also pitched well. In honor of the pitching duo,
Boston Post sports editor Gerald V. Hern wrote this poem which the popular media eventually condensed to "
Spahn and Sain and Pray for Rain": First we'll use Spahn then we'll use Sain Then an off day followed by rain Back will come Spahn followed by Sain And followed we hope by two days of rain. The poem was inspired by the performance of Spahn and Sain during the Braves' 1948 pennant drive. The team swept a
Labor Day doubleheader, with Spahn throwing a complete 14-inning win in the opener, and Sain pitching a shutout in the second game. Following two off days, it did rain. Spahn won the next day, and Sain won the day after that. Three days later, Spahn won again. Sain won the next day. After one more off day, the two pitchers were brought back, and won another doubleheader. The two pitchers had gone 8–0 in 12 days' time. Other sayings have been derived from "Spahn and Sain and pray for rain." For example, some referred to the
1993 San Francisco Giants' imbalanced rotation as "
Burkett and
Swift and pray for snow drift." In 1957, Spahn was the ace of the champion
Milwaukee Braves. He pitched on two other Braves pennant winners, in 1948 and 1958. Spahn led the NL in strikeouts for four consecutive seasons, from 1949 to 1952 (tied with Don Newcombe in 1951), which includes a single-game high of 18 strikeouts in a 15-inning appearance on June 14, 1952. During the
1957 World Series,
Sal Maglie of the Yankees, ineligible to pitch in the series because he was acquired too late in the season, watched the games with Robert Creamer of
Sports Illustrated and made assessments of the players. When Spahn was pitching, Maglie observed that batters had to try to hit balls to the opposite field against Spahn, as he was more likely to get them out if they tried to pull the ball. On July 2, 1963, facing the
San Francisco Giants, the 42-year-old Spahn became locked into a storied pitchers' duel with 25-year-old
Juan Marichal. The score was still 0–0 after more than four hours when Willie Mays hit a game-winning solo home run off Spahn with one out in the bottom of the 16th inning. Marichal's manager,
Alvin Dark, visited the mound in the 9th, 10th, 11th, 13th, and 14th innings, and was talked out of removing Marichal each time. During the 14th-inning visit, Marichal told Dark, "Do you see that man pitching for the other side? Do you know that man is 42 years old? I'm only 25. If that man is on the mound, nobody is going to take me out of here." Marichal ended up throwing 227 pitches in the complete game 1–0 win, while Spahn threw 201 in the loss, allowing nine hits and one walk. Spahn threw his first no-hitter against the Philadelphia Phillies on September 16, 1960, when he was 39. He pitched his second no-hitter the following year on April 28, 1961, against the Giants. During the last two seasons of his career, Spahn was the oldest active player in baseball. He lost this distinction for a single day: September 25, 1965, when 58-year-old
Satchel Paige pitched three innings. Spahn's seemingly ageless ability caused
Stan Musial to quip, "I don't think Spahn will ever get into the Hall of Fame. He'll never stop pitching." He signed with the San Francisco Giants, with whom he appeared in his final major league game on October 1, 1965, at the age of 44. With the Mets and Giants combined, he won seven games for the season—his last in the major leagues. His 363 career win total ranks sixth overall in major league history; it is also the most by a pitcher who played his entire career in the post-1920
live-ball era. ==Later life==
