Who is the youngest Minnesota Twins player to make his major league debut wearing a Twins uniform? That would be right-handed pitcher Jim Manning who was born in L’Anse, Michigan on July 21, 1943 and went on to become a legendary high school basketball player winning All-State honors as a junior and as a senior. Jim held the U.P. record of most points scored in his four-year career with a total of 2,137 points, all without playing with a 3-point line. While in high school he was offered a full scholarship to the University of Wisconsin-Madison in basketball and according to Tom Briere of the Minneapolis Tribune, Manning was all set to sign a baseball-basketball scholarship with the Minnesota Gophers, but declined because his first love was always baseball and the Minnesota Twins snatched him up.
After signing with the Twins for $20,000 fresh from high school, the Michigan native pitched in 12 games for Wytheville of the short-season Class D Appalachian League in 1961. Dividing his time between starting and relief, he went 2-2 with a 4.40 ERA. Others playing at Wytheville that season included future Hall of Famer Tony Oliva, who hit .410 in 64 games, and future Twins infielder and manager Frank Quilici.
Manning entered spring training 1962 with the Twins with the slimmest of chances to make the team. The Twins went with a youth movement in 1962, their second season in Minnesota after relocating from Washington, with The Sporting News commenting on the team’s “incubator infield” of 23-year-old third baseman Rich Rollins, 22-year-old second baseman Bernie Allen, and 22-year-old shortstop Zoilo Versalles. Joe Bonikowski, a 21-year-old pitcher, made the team with a strong spring training, as did a relative graybeard, 25-year-old rookie Lee Stange. (Starting pitcher Jim Kaat was 23 but was no newcomer, beginning his fourth season with the franchise. Manning, just 18 also pitched his way on to the team. He secured another niche in Twins history when he was issued jersey number 42, becoming the first Twin to wear that number although this point has been questioned.
Manning’s big league career consisted of just 5 games, all with the Minnesota Twins. The amazing part is that he did it at the age of 18 after appearing in just 12 games in the Appalachian League a year earlier.
