Giants vs Royals Prediction

The Giants won six of the previous ten H2H encounters, including four of the last five. Even though it’s very ungrateful to bet on Over when the Royals are involved, I am going with Over because I don’t like the starting pitchers. Michael Lorenzen allowed nine runs in his last three starts, including five home runs. He allowed a .326 BA in 43 at-bats against San Francisco. Hayden Birdsong, on the other hand, is a reliever, not a starter, and this will be his first start of the year. I don’t know how many innings he’ll stay on the mound, but I am pretty sure the Royals will score a run or two off him early on. Go with Over.
