Name: Yu Darvish
Born: 8/16/1986 in Osaka, Japan
HT: 6’5” WT: 215
Yu Darvish is an effective low to mid 90’s pitcher. He also has a good set of pitches to complement his fastball. In the video analysis above I breakdown his biomechanics listing the pros an cons. I used the 3X Evaluation System which measures angles, distances and time of movements. It then rates these metrics based on science that have found high correlation of specific metrics to high velocity pitchers.
Here is a list of the pros or positives in Yu Darvish’s pitching mechanics along with the cons or negatives.
- Separation Timing
- Contralateral Tilt at Maximum External Rotation
- Front Foot Position at Front Foot Strike
- Hip Rotation at Front Foot Strike
- Front Leg Extension Before Pitch Release
- Shoulder Abduction at Front Foot Strike
Summary of Yu Darvish’s Pitching Mechanics
Yu Darvish uses a hybrid version of a rotation back leg and a 3X back leg drive. To learn more about drive leg styles checkout this video. His limited drive leg force production creates poor hip rotation into front foot strike. This coupled with a poor front leg extension into pitch release forces him to hyper-abduct the throwing arm and counter rotate more than needed with his shoulder orientation at front foot strike. The negative to this overcompensation is added stress to the shoulder and elbow joint which occurs during this hyper-abduction and later during maximum external rotation as he moves too far into horizontal abduction with the throwing elbow.
This overcompensation does allow him to still gain good hip to shoulder separation timing in his pitching delivery which is why he is able to consistently pitch in the low to mid 90’s. If he was to learn a more 3X drive leg and 2X landing leg approach this would create more hip rotation at front foot strike and more hip rotation into maximum external rotation then he would not need to hyper-abduct the throwing arm and counter rotate so much to separate his hips from shoulders and this would eliminate the added horizontal adduction of the throwing arm at maximum external rotation.
