PQ seemed pretty good to me, although some cameras seemed clearer than others. For some sporting events, broadcasters do not always use HD cameras for all their coverage. Shots of the dugout or the crowd are sometimes shown in "enhanced definition" which is roughly 480p, but still in 16 x 9 format. I didn't notice any enhanced definition shots, but I was bouncing back and forth between 2 games...
BTW, the TBS PQ was excellent for the Orioles/Red Sox game.
