Set your grip (before takeout) so that your middle knuckle is pointing up (so, more straight wrists) and elbows slightly in front of the bar. Get nice and tight, with tight armpits before you take it out. Then don't rush the reps. If you do them touch and go like that you risk the bar path going all over the place and pushing the bar away (which happens on some reps). Pause at the bottom, take a breath and get tight (ribs down, abs tight), and then do the next rep.
