“Ninety Percent Mental” with Bob Tewksbury

“Ninety Percent Mental” with Bob Tewksbury

Bob Tewksbury was never considered an overpowering pitcher. He was however the definition of a cerebral pitcher.

Bob Tewksbury was drafted by the Yankees in the 19th round back in 1981. In his 13 years in MLB, he played for NYY, CHC, STL, TEX, SDP, and MIN. He has a lifetime 110-102 record, 3.92 ERA, and led MLB 2x in BB/9.

Tewksbury is notoriously known for being a cerebral pitcher. He got by with his pinpoint control and by trusting his fielders behind him. In 1992, at age 31, Tewks was selected to the ASG and placed 3rd in the Cy Young voting.

Most recently, Tewksbury was a mental skills coach for the San Francisco Giants. Before that he worked for the Boston Red Sox.

Today, Tewksbury joined WTTS to talk about his newest book “Ninety Percent Mental.” In this book, he explores the psychology behind baseball. We talk about how a technique called “mental imagery” can maximize performance. Also, we explore how Tewks uses this techniques with MLB superstars like Jon Lester, Andrew Miller, Anthony Rizzo, and Rich Hill.
