its S2
they had a 3 game losing streak on the road, the streak was broken and we contunie playing the streak. Means we play Pittsburgh to lose on the road. So play is/was on Arizona.
On a sidenote Pittsburgh losing streaks are also S1 plays, we do skip 2 plays after the streak was broken and play to fade them right after those 2 games. So we will also have a S1 Pit fade starting on 22.04.2013, when they are going to play their next game on the road.
