His average went from 112mph to 119mph which is roughly 20 yards. By lifting his left heel on his backswing, not only does that help his right hip to turn back more creating a bigger turn, but by squashing that left heel back into the ground at the top of his swing, helps him to squat and get his sequencing better, where he can explode off the ground more and create more speed. Thx for the power tip Camo 👍🏼 #LDTips #CTTip #power #distance #staysafe #stayhealthy」5月21日 6時18分
