Phillies vs Diamondbacks Prediction, Betting Analysis
Taijuan Walker is going to be piggybacking tonight. With Walker Buehler today, and so in a piggyback situation, the starter usually doesn't go as long as he normally does.
So Walker might only go four innings today, maybe five. I doubt any longer than that. And so if we're getting a five-and-a-half line at any sort of reasonable odds, I think that is a great bet today because Walker probably will not be in the game long enough to give up that many hits unless he is just really, really bad.
Pick: Taijuan Walker Under 5.5 Hits Allowed
