The following are the baseball events of the year 1969 throughout the world.  

Four expansion teams joined Major League Baseball for this season: the San Diego Padres, the Kansas City Royals, the Seattle Pilots, and the first MLB team in Canada, the Montreal Expos. To accommodate the additional teams, the two leagues were split into two divisions of East and West. For the first time, extra post-season playoff series were added prior to the World Series, at this juncture best-of-five series between the East and West division leaders in each league.

The most notable part of the 1969 season were the Miracle Mets

The save is introduced as an official statistic this year. Ron Perranoski leads the majors with 31.

Peter Edward Rose (born April 14, 1941), nicknamed "Charlie Hustle", is a former Major League Baseball player and manager. Rose played from 1963 to 1986, and managed from 1984 to 1989.

Rose, a switch hitter, is the all-time Major League leader in hits (4,256), games played (3,562), at-bats (14,053) and outs (10,328). He won three World Series rings, three batting titles, one Most Valuable Player Award, two Gold Gloves, the Rookie of the Year Award, and made 17 All-Star appearances at an unequaled five different positions (2B, LF, RF, 3B & 1B).

In August 1989, three years after he retired as an active player, Rose agreed to permanent ineligibility from baseball amidst accusations that he gambled on baseball games while playing for and managing the Reds, including claims that he bet on his own team. In 1991, the Baseball Hall of Fame formally voted to ban those on the "permanently ineligible" list from induction, after previously excluding such players by informal agreement among voters. In 2004, after years of public denial, Rose admitted to betting on baseball and on, but not against, the Reds. The issue of Rose's possible re-instatement, and election, to the Hall of Fame remains a contentious one throughout baseball.

Mickey Charles Mantle (October 20, 1931 – August 13, 1995) was an American baseball center fielder who played 18 seasons in Major League Baseball (MLB) for the New York Yankees from 1951 to 1968. Mantle is regarded by many to be the greatest switch hitter of all time, and one of the greatest players in baseball history. Mantle was inducted into the National Baseball Hall of Fame in 1974 and was elected to the Major League Baseball All-Century Team in 1999.

Mantle was noted for his hitting ability, both for average and for power.^{[citation needed]} He won the Triple Crown in 1956, leading MLB in batting average, home runs, and runs batted in (RBI). He received three American League (AL) Most Valuable Player (MVP) Awards and played in twenty All-Star games. Mantle appeared in 12 World Series, winning 7 of them. He holds the records for most World Series home runs (18), RBIs (40), runs (42), walks (43), extra-base hits (26), and total bases (123). He is also the career leader in walk-off home runs, with a combined thirteen, twelve in the regular season and one in the postseason.

Lynn Nolan Ryan, Jr. (born on January 31, 1947), nicknamed "The Ryan Express", is a former Major League Baseball pitcher. He is currently principal owner, president and CEO of the Texas Rangers.

During a major league record 27-year baseball career, he pitched in 1966 and from 1968 to 1993 for four different teams: the New York Mets, California Angels, Houston Astros, and Texas Rangers. He was inducted into the Baseball Hall of Fame in 1999.

Ryan, a hard-throwing right-handed pitcher, threw pitches that were regularly recorded above 100 miles per hour (160.93 km/h). The high velocity remained throughout his career, even into his 40s. Ryan was also known to throw a devastating 12–6 curveball at exceptional velocity for a breaking ball.

While his lifetime winning percentage was a relatively pedestrian .526, Ryan was an eight-time MLB All-Star, and his 5,714 career strikeouts rank first in baseball history 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 Major League history. Other than Jackie Robinson (whose number was retired by the entire MLB), Ryan is currently the only major league baseball player to have his number retired by at least 3 different teams: the Angels, Astros, and Rangers.

Reginald Martinez "Reggie" Jackson (born May 18, 1946) is an American former baseball right fielder who played 21 seasons in Major League Baseball (MLB) for four different teams (1967–1987). He was nicknamed "Mr. October" for his clutch hitting in the postseason with the New York Yankees. Jackson won five consecutive American League West divisional pennants, three consecutive American League pennants and two consecutive World Series titles as a member of the Oakland Athletics (he did not play in the 1972 World Series due to injury) from 1971 to 1975; four American League East divisional pennants, three American League pennants and two consecutive World Series titles with the Yankees from 1977 to 1981; and two American League West divisional pennants with the California Angels in 1982 and 1986. He is perhaps best remembered for hitting three consecutive home runs in the clinching game of the 1977 World Series.

Jackson played for the Kansas City / Oakland Athletics (1967–1975, 1987), Baltimore Orioles (1976), New York Yankees (1977–1981), and California Angels (1982–1986). A 14-time All-Star and five-time World Series champion, Jackson won two Silver Slugger Awards, the 1973 American League (AL) Most Valuable Player (MVP) Award, two World Series MVP Awards, and the 1977 Babe Ruth Award.
