About John Mayberry
Born 1949. John Mayberry is an American baseball player.
John Claiborn Mayberry Sr. (born February 18, 1949) is an American former Major League Baseball player who was active from 1968 to 1982 for the Houston Astros, Kansas City Royals, Toronto Blue Jays and New York Yankees. He was a two-time All Star.
High school and minor leagues Mayberry attended Northwestern High School, graduating in 1967. He was a gifted high school athlete, playing baseball, football, and basketball at Northwestern; John was twice named to the Detroit News All-State Basketball Team. After graduation, Mayberry was selected by the Houston Astros in the first round (sixth overall) of the 1967 Major League Baseball draft. He was the second first baseman taken in the draft, Ron Blomberg having been selected number one overall by the New York Yankees.
As an 18-year-old, Mayberry was assigned to the Covington Astros of the Appalachian League. While there, he batted .252 in the 1967 season, hitting 4 home runs in 155 at-bats. He continued to develop the following season, making appearances at three different levels of minor league baseball. His batting average for the 1968 season was a robust .320, with a high of .338 in 195 at-bats for the Cocoa Astros of the Florida State League. Between three levels, Mayberry hit 23 home runs and slugged .552. During his four-game call-up, Mayberry recalled the first time he met Hank Aaron, who was playing for the Atlanta Braves: I just stood there looking at him,' Mayberry said. 'I said to myself, "so this is the Hammer, this is Henry Aaron.
At 20 years old, Mayberry played 123 games for the Oklahoma City 89ers of the AAA-level American Association. With 21 home runs, a .303 batting average, and a .522 slugging percentage, his power began to resemble the man he met the year before in the majors. He batted in 78 runs and scored 95, walking more times than he struck out (62/42). That would not come until the following year; after playing 70 games at Oklahoma City and batting .273 with 13 home runs, Mayberry was called up to the Houston Astros.
Major league career
Houston Astros Mayberry played in 50 games during his first extended stint in "the Show", with his first career hit coming in April 1970 before he was sent back down to AAA. It came against the San Francisco Giants in a 7β4 loss; he hit a single to right field off Giants right-hander Frank Reberger. The 1971 season was yet another year split between the minor leagues and the major leagues. While he hit .324 with 13 home runs in 64 games in the minors that year, The trade turned out to be very one-sided in favor of the Royals.
Mayberry's best season in Kansas City was in 1975. He set career marks in doubles, home runs, runs scored, and RBI. He was named the American League Player of the Month in July 1975 for hitting 12 home runs and posting a .365 batting average, He also had an eight-game stretch during which he hit eight home runs.
During the 1977 American League Championship Series against the New York Yankees, Mayberry arrived late for the fourth game, which was played in the afternoon, after a late-night outing. Mayberry played very poorly on both offense (striking out twice in two plate appearances) and defense (dropping a foul pop and a routine infield throw). Mayberry's ragged play prompted manager Whitey Herzog to bench him midway through Game Four and to leave him out of the starting lineup for the decisive fifth game.
Herzog later blamed Mayberry for the Royals' failure to defeat the Yankees in the ALCS and demanded Mayberry's dismissal from the team, even though he also said he had "always loved the way John played". Consequently, before the start of the 1978 season, the Royals sold Mayberry to the Toronto Blue Jays, who were beginning their second season of play in the American League. John Jr. hit his first two career home runs in 2009 against his father's last two teams.
