In Part II of Baseball Time in Arlington’s three-part Q&A series with Coach Bagonzi, the venerable pitching expert weighs in on the ever-controversial Dr. Mike Marshall, velocity and the Magnus Effect, and the importance of training the lower body for pitchers of all ages, as well as several other topics of great interest.
Coach Bagonzi on "doctoring" a fastball:
"All the time spent on “doctoring” the fastball is well worth it, because movement is priceless and important to pitching success. Having three or four types of fastballs surely fortifies one’s pitching kit - a riser, a tailer, a sinker and perhaps a cutter makes four pitches all coming out of the same delivery slot. Spin direction and amount of spin would be something all pitchers would do well to completely understand and master, for this is responsible for critical fastball movement."
Curious to hear your thoughts.
