I hate calling plays "sucker bets", its a little disrespectful to those that took it. I will say I had Miami too, and it played on a nice angle that usually gets you on a nice dog.
Its a pitcher rematch angle, playing the same teams and pitchers in their next start. You are playing ON the pitcher that took the Loss in the last game, provided he had a good outing. In the last game, Koehler went 6 innings allowing 2 ER - 5 Hits - 2 Walks - 6 Ks. It was obscured as the team lost 7-1. That was a very good outing and he again delivered a solid performance against Strasburg.
