Expect another high-scoring game, especially at Chase Field in Phoenix.
The Diamondbacks came back down to earth a bit in Game 2, but the results were the same, as Arizona won the series on Tuesday. That was all in big thanks to Ketel Marte, who hit a game-winning three-run homer in the bottom of the ninth with two outs. Arizona scored in the first inning on an RBI triple by Corbin Caroll. The Diamondbacks couldn’t score again until they put up four runs, highlighted by Marte’s heroics. The rally started with an RBI single to center by Adrian Del Castillo. San Francisco looked primed to win after it scored all three of its runs in the second inning, highlighted by solo shots from Rafael Devers and Willy Adames.
San Francisco had a 96.5 percent chance in the ninth inning to tie this series. It was a devastating loss and erased a good start from Giants starter Landen Roupp, who went six innings while only giving up one run on seven hits.
