just my opinion:
Tampa hasn't been putting up many runs plus they travelled quite far as of the past week and a half, making me think that their timing may be a little off. They are also facing a tough pitcher. Boston has drew and youk questionable, they may play but still boston is facing a good pitcher too. The bullpen can shut each other down as both have good arms. The line is at 9 so I would take the safer of the plays and stick with the under
Once again just my opinion good luck mate
