Robin Evan Roberts (September 30, 1926 – May 6, 2010) was a Major League Baseball starting pitcher who pitched primarily for the Philadelphia Phillies (1948–61). He spent the latter part of his career with the Baltimore Orioles (1962–65), Houston Astros (1965–66), and Chicago Cubs (1966). He was inducted into the Baseball Hall of Fame in 1976.
Roberts was born in Springfield, Illinois, the son of an immigrant Welsh coal miner. He arrived in East Lansing, Michigan as part of an Army Air Corps training program. After World War II, Roberts returned to Michigan State College to play basketball, not baseball. Roberts led the Spartans' basketball team in field-goal percentage in 1946–1947, was captain of the team during the 1946–1947 and 1949–1950 seasons, and earned three varsity letters in basketball. He wore number 17 for the Spartans. After his second season playing basketball, Roberts tried out for the Michigan State baseball team, becoming a pitcher because it was the position that coach John Kobs needed most. After playing for Michigan State and spending his second summer playing in Vermont with the Barre–Montpelier Twin City Trojans, he was signed by the Phillies.
Roberts made his major league debut on June 18, 1948, and in 1950 he led his Phillies—whose overall youth earned them the nickname the Whiz Kids—to their first National League pennant in 35 years. Roberts started three games in the last five days of the season, defeating the heavily favored Brooklyn Dodgers at Ebbets Field, in a pennant-deciding, 10-inning game. This marked his 20th victory of the season and Roberts became the Phillies' first 20-game-winner since Grover Cleveland Alexander in 1917.
