This is the first game of a doubleheader. Both of these starting rotations have been killing opponents, and the Giants have won five straight. They went into Cleveland over the weekend and allowed only four runs in a three-game sweep. The Mets starting rotation's ERA is 1.07, and Tylor Megill has allowed no runs in two starts. But the Giants' Alex Cobb looked unhittable, striking out 10 Padres in five innings of work in his first start. Giants to win.
