Jerome Martin Koosman was an American professional baseball player. He was a famous left-handed pitcher who played in Major League Baseball (MLB). Over his long career, he played for the New York Mets, Minnesota Twins, Chicago White Sox, and Philadelphia Phillies. He is best remembered as a hero of the Miracle Mets. That team surprised the sports world by winning the championship in the 1969 World Series.

Early Life and Discovering a Star Pitcher
Koosman grew up in the small town of Appleton, Minnesota. He loved playing sports and learned how to throw a baseball with tremendous power. When he grew older, he joined the United States Army and was stationed at Fort Bliss in Texas.
While serving his country, Koosman continued to pitch on military baseball teams. A man named John Lucchese, whose father worked as an usher at Shea Stadium, caught his pitches. Lucchese saw Koosman's rare talent and told the scouts for the New York Mets. The team liked what they saw and offered Koosman a professional contract.
Starting out in professional sports is not always easy. When Koosman first drove to spring training, his car broke down along the highway. The team had to wire him money so he could fix the car and finish his journey. Joe McDonald, an assistant director in the team's system, made sure the club kept Koosman on the roster. That small act of kindness helped keep Koosman in baseball, and he soon showed how great he could be.
Becoming an Ace for the New York Mets
Setting Records in a Dazzling Rookie Season
Koosman worked hard in the minor leagues to improve his control and speed. In 1967, he led all International League pitchers by throwing the most strikeouts. That success earned him a permanent spot in the major leagues for 1968.
His first full year with the Mets was historic. He won 19 games and lost only 12. Even more amazing, he pitched seven complete shutout games, meaning the other team never scored a single run against him. He struck out 178 batters and finished with a tiny 2.08 earned run average.
These marks broke franchise records previously set by his superstar teammate, Tom Seaver. Baseball fans and players took notice right away. Koosman was selected to play in the prestigious Major League Baseball All-Star Game. In that classic game, the National League won by a score of 1–0. Koosman came into the game in the ninth inning to earn the save. He struck out the legendary hitter Carl Yastrzemski to secure the victory.
At the end of the year, Koosman was picked for the Topps All-Star Rookie Rosters. He finished as the runner-up for the National League MLB Rookie of the Year Award, just behind future legend Johnny Bench.
The Miracle Mets of 1969
In 1969, Koosman proved his great rookie season was no accident. He won 17 games, struck out 180 batters, and earned another trip to the All-Star Game. The Mets had spent years at the bottom of the standings. That summer, they surprised everyone by chasing down the first-place Chicago Cubs.
The Mets fought back from being 91⁄2 games behind to win the National League East division. After a tough loss to the Houston Astros, Koosman became almost unbeatable, winning eight of his next nine starts. The team moved on to the 1969 National League Championship Series to face the powerful Atlanta Braves. Even though slugger Hank Aaron hit a home run against him, the Mets rallied to win the game and swept the series.
World Series Glory Against the Baltimore Orioles
The Mets faced the heavily favored Baltimore Orioles in the 1969 World Series. After losing the first game, the Mets turned to Koosman in Game Two. He pitched brilliantly, not allowing a single hit until outfielder Paul Blair hit a single in the seventh inning. Star player Brooks Robinson drove in a run, but Koosman kept his cool. Reliever Ron Taylor helped finish the game, giving the Mets a huge win.
The series then moved to New York. The Mets won Games Three and Four, putting them just one win away from a championship title. Koosman took the mound for Game Five. The Orioles jumped out to an early 3–0 lead with home runs from pitcher Dave McNally and slugger Frank Robinson.
Koosman refused to give up. His teammates supported him with big hits. First baseman Donn Clendenon smashed a two-run homer. Then, infielder Al Weis hit a shocking home run to tie the game. The Mets scored two more runs to take the lead. In the ninth inning, Koosman retired the final batters. Outfielder Cleon Jones caught a fly ball hit by Davey Johnson to end the game. The Mets had won their very first World Series crown, completing one of the greatest upsets in sports history.
The Famous Game Five Baseball
When the final out was made, Cleon Jones ran in from the outfield and handed the baseball to Koosman. Koosman kept that historic ball, along with the ball from his Game Two win, locked safely inside his home. It stood as a symbol of how teamwork and perseverance could accomplish the impossible.
The Unforgettable 1973 Pennant Race
"Ya Gotta Believe!" and Pitching Records
After battling an arm injury during the 1971 season, Koosman returned to top form. In 1973, he helped lead another impossible comeback. During the late summer, he set a Mets record by pitching 312⁄3 straight innings without allowing a single run. That record stood for decades until R. A. Dickey broke it in 2012.
Once again, the Mets caught the Cubs from nine games back. Relief pitcher Tug McGraw energized the team and the city by shouting, "Ya Gotta Believe!" Manager Yogi Berra gave fans another famous quote: "It ain’t over 'til it's over." The pitching trio of Koosman, Tom Seaver, and Jon Matlack carried the team into first place.
The Playoffs and the Fall Classic
In the 1973 National League Championship Series, the Mets battled the mighty Cincinnati Reds. Koosman pitched a complete game in Game Three, earning a dominant 9–2 win. The contest was famous for a heated scuffle between superstar Pete Rose and Mets shortstop Bud Harrelson. The Mets won the pennant two games later.
In the 1973 World Series, the Mets faced the powerful Oakland Athletics. Koosman pitched like a champion in Game Five. He did not allow a single run over 61⁄3 innings, giving the Mets a crucial victory. Even though Oakland eventually won the title in seven games, Koosman proved he was one of the best clutch pitchers in baseball history.
Later Years with the Mets and Career Bests
Koosman had an incredible season in 1976. He won 21 games, struck out 200 batters, and finished second in the voting for the prestigious Cy Young Award, just behind Randy Jones.
By 1977, the Mets were rebuilding their team. They traded Seaver away, and the team struggled to win games. Koosman worked hard, but the lack of team offense led to a league-high number of losses alongside pitcher Phil Niekro. By the end of 1978, only first baseman Ed Kranepool remained from the original 1969 championship squad. Koosman asked to be traded so he could play for his home state team, the Minnesota Twins. In exchange, the Mets received young pitcher Jesse Orosco, who had been a player to be named later.
Playing for New Teams and Career Milestones
Returning home energized Koosman. In 1979, he won 20 games for the Twins. After the 1981 Major League Baseball strike, he was traded to the Chicago White Sox. Koosman helped Chicago capture the American League West division title in 1983, leading the team to its first playoff appearance since the 1959 World Series.
Koosman finished his playing career with the Philadelphia Phillies. On April 13, 1984, he threw a pitch to Pete Rose, who hit a double for his 4,000th career hit. Koosman retired after the 1985 season.
Over his career, Koosman achieved great milestones:
- He won 222 total games, putting him in a tie with Hooks Dauss on the all-time win list.
- He struck out 2,556 batters over his career, ranking him high on the all-time strikeout list.
- He pitched 3,8391⁄3 total innings pitched.
- His 140 wins with the Mets remain the third most in team history, behind only Tom Seaver and Dwight Gooden.
Honors, Retired Jersey, and Legacy
Koosman was inducted into the New York Mets Hall of Fame in 1989. Fans always cheered loudly whenever he visited the ballpark. He proudly returned to New York to celebrate the 40th anniversary of the 1969 championship at Citi Field.
On August 28, 2021, the Mets honored him with one of the highest awards in sports: they retired his jersey number 36. That meant no other Mets player would ever wear that number again. At the time, he was only the third Mets player to receive this special honor, joining Tom Seaver and Mike Piazza. Later, great Mets such as Keith Hernandez, Willie Mays, Dwight Gooden, Darryl Strawberry, David Wright, and Carlos Beltrán had their numbers retired as well.
Koosman passed away on November 1, 2026, at the age of 83. Baseball fans around the world remember him as an incredible athlete, a World Series champion, and a true hero of the Miracle Mets.
