The San Francisco Giants have chosen the most direct route back into relevance: straight over the wall. The back-to-back jolts extended San Francisco’s home run streak to 18 games in an 8-2 win over the Cardinals, one shy of the franchise record set by the 1947 New York Giants. It was the fourth time the Giants have gone back-to-back this season — and the second time in seven games it’s been Devers and Adames doing the honors. San Francisco racked up 18 hits — matching its season high — and has piled up a staggering 70 knocks over its last five games, the most in any five-game span since the franchise moved west.
