James Reynold Lonborg (April 16, 1942- ) was a starting pitcher with the Boston Red Sox (1965-1971), Milwaukee Brewers (1972) and Philadelphia Phillies (1973-1979). Longborg's greatest season was in 1967 when he went 22-9 with a 3.14 ERA, earned his lone trip to the All-Star Game and won the American League Cy Young Award. He had three starts in the World Series that season. He was 2-1 with a 2.63 ERA in the series, though the Red Sox lost in seven games. He pitched steadily, if not brilliantly for the remainder of his career and retired with a 157-137 record and a 3.86 ERA.
