Robert Rock graciously joined me on Periscope — you can watch it on the app for the full experience — on the range at Royal County Down, the venue for this week’s Irish Open, which is hosted by world no. 1 Rory McIlroy.

Rock analyzes the swing of fellow European Tour player Oliver Wilson, and 2016 European Ryder Cup captain Darren Clarke makes a funny cameo around the six-minute mark. Rock also answers questions from commenters and gives a bevy of swing tips.

Give it a watch — it’s great fun and you might learn a thing or two!
