Open Extended ReactionsSPA-FRANCORCHAMPS, Belgium -- Lewis Hamilton labeled his performance at the Belgian Grand Prix "unacceptable," saying he had to look internally to find answers about a miserable week so far. For the second time in two days, Hamilton was eliminated in the Q1 session -- he had spun during sprint qualifying on Friday and then failed to progress from the proper qualifying session again 24 hours later. A lap he had set, which was good enough to advance, was deleted for a track limits violation at the top of the famous Eau Rouge. "I've got to look internally and apologize to the team because it's unacceptable to be out in Q1, it's [a] very very poor performance," Hamilton told Sky Sports News after qualifying 16th. Lewis Hamilton finished 15th in the sprint race and qualified 16th for Sunday's race.
