Bob Tewksbury had a 13-year big league career after being drafted by the New York Yankees in the 19th round of the 1981 Amateur Draft. He did not strike out may batters, only topping 5 strikeouts per nine innings twice, but also did not walk many. In his 13 years, he issued 292 bases on balls, twice leading his league in walks per nine innings (1992 & 1993, 0.8 both years); the most batters he walked in a season was 43 for the 1996 Padres. (The same season, incidentally, he registered his most strikeouts per nine innings, 5.5) He was regarded as an outstanding fielding pitcher, but never won a Gold Glove. He was an All-Star in 1992 and was third in the Cy Young Award voting that year.
After his baseball career ended, Tewksbury joined the Boston Red Sox as an advance scout in 1999. From 1999-2004, Tewksbury served as a pitching consultant, working with pitchers in Double-A and Triple-A. He earned a Masters degree in sports psychology and counseling from Boston University in 2004. In 2005, the Red Sox named him as the team's Mental Skills Coach. He left that position in 2014 to become the director of player development for the Major League Baseball Players Association, returning again as the Mental Skills Coach with the Red Sox in 2015.
