Royals vs Giants Prediction

The Giants won six of the previous ten H2H encounters, including five of the last six. I don’t know who will start for the Royals, but it may be a bullpen day for KC. Logan Webb, on the other hand, is San Francisco’s ace this year and registered three straight quality starts, allowing only four runs in the process. Webb allowed a .256 BA in 39 at-bats against the Royals in his career. I am sure Webb will add another QS against one of the worst offensive teams in the MLB. Back the Giants to win and cover the run line.
