At the start it looked like a little of both. SL didn't break smoothly, and then Irad bumped him a little. But in the stretch it was all SL - it looked like he may have bumped Honor M and then veered in sharply and bumped someone else. I was surprised there was no inquiry. I'm wondering if he gets spooked by crowd noise, and maybe they should try those Gate Dancer ear muffs on him.
