Jon Lester Continues to Develop Pitching Arsenal to Balance Attack From the Mound

As each season goes by, Jon Lester learns something new about the pitches in his arsenal and how he can improve in the years to come.

Even last season, when the Red Sox' ace posted an incredible 19-9 record, he found that he was relying too much on his cutter at times and not exploring other pitch options.

"Last year, Victor [Martinez] and I kind of got into a little bit of a rut," Lester said during an interview with Peter Gammons. "I had a good one going … it was a quality cutter, and it was like he overused it sometimes. That's my fault as well, I felt comfortable with it, and not shaking to another pitch."

In the past, Lester has come into spring training with the goal of developing the strength of one pitch. This season, however, has become more about the mechanics for the five-year veteran, and he'll work on refining each pitch, finding the feel for each one as he nears the regular season.
