Giants vs Marlins Prediction
The Marlins are 6-2 in their last 9 meetings against the Giants and are 3-1 in their last 4 meetings in Miami.
In this Giants vs Marlins Prediction, the Giants are coming as -160 road favorites. I’m with the Giants in this one with the red-hot Logan Webb on the mound, who has been unhittable as of late, with just two earned runs across his last four starts. He will go up against Ryan Gusto, who has given up 8 runs in two of his three starts combined, having struck out just twice in those two games. Take the Giants here to win and avoid the series sweep on the road.
