It is incredible that three or four teams from the NL West could reach the playoffs! I’m feeling positive that the Diamondbacks will obtain a wild-card berth.
If the Giants fail to win the NL West (which is likely), they are competing with the D-backs for a wild-card spot, making a series win important, both for the win and for the potential tiebreaker.
The Diamondbacks have more runs scored per game than the Giants. That’s one reason for optimism. Ketel Marte is in the lineup. That’s another reason for optimism. The Giants come into this series having been swept by the Twins (scoring a total of 2 runs in the first two games).
