San Francisco Giants vs. Tampa Bay Rays Prediction

I’m on the Giants in this one. Landen Roupp’s been one of the best options that the Giants have had this season and he’s been responsible for a fair number of their wins so far this season. Jax is probably a spot starter or opener for a bullpen game, and if that’s the case, Tampa Bay’s bullpen is still very hard to trust right now and I think the Giants take care of business here. Give me the Giants.
