Ever since 2005 this is roddick's play style. Go run around backhand, hit inside-out forehands repeatedly. OR Hit the cross court shots 5 times in a row, then maybe if the opponent switches it up, you change to inside out and hit 5 more of those in the same spot. Also when he slices, it always comes in groups or pairs, you rarely see him do 1 slice, its either 2 or 3 or 4 in a row. This guy hates changing direction, unlike Federer and Djokovic.
