I love the way he keeps the club between his arms on the way back, subtly shallows out on transition and tumbles with his whole upper body through release. A middle of the matrix tumbler, but maybe a hair closer to sergio than watson. A very neutral swing for an athletic but not overly flexible player- great control of how each segments accelerates in the kinetic chain. Some younger long hitters stretch out too much during transition which is powerful but makes speed transfer through the kinetic chain hard to control, but stenson controls it nicely with his arm, shoulder, hip, knee tension. His pivot seems very much like step on right foot bam, then step on left foot bam.
