If I understand you correctly I think you mean you can play a parley on the game, but it would have to be on the game and the over/under. I think a parley would be the best way to take advantage in the sense that you could win more, but obviously its a harder bet.
My opinion is that the over is the strongest play. If going for the parley I would take yanks and over.
regarding ponson from the net:
"He hasn't pitched in the majors since starting for New York last Aug. 18, when he was ripped for seven runs and nine hits in three innings of a 14-11 win at Boston. It was his fifth appearance and third start as a Yankee - he went 0-1 with a 10.47 ERA - and the team designated him for assignment the following day before eventually releasing him.
