The San Francisco Giants enter Giants Vs Diamondbacks with one blunt number hanging over them: 0-6. Arizona has taken every meeting between the teams this season, and the Diamondbacks have done it by a combined plus-22 run differential, turning a division matchup into a one-sided season series.
That is why the search for Giants Vs Diamondbacks spikes now. The Giants are 12-12 in June and have been playing better lately than Arizona, yet they still have not solved a team that has owned them from the first pitch of the year to now. The Diamondbacks are 6-0 against San Francisco this season, and the gap is large enough that the next game feels less like another date on the calendar and more like a test of whether the Giants can finally make the series resemble their recent form.
There is evidence on both sides of that argument. The Diamondbacks were 31-24 after sweeping the Giants in Arizona about a month ago, with Corbin Carroll, Nolan Arenado, Ildemaro Vargas and Ketel Marte all posting strong production at that point. Arizona’s rotation also looked sturdy then, with Michael Soroka at 1.6 fWAR and a 2.87 FIP, and Eduardo Rodriguez at 1.1 fWAR with a 3.73 FIP. San Francisco, meanwhile, had not separated itself, but the numbers suggested a club capable of closing the gap if its offense kept moving forward.
That is where the story turns. Since that sweep, Arizona has gone 10-18 and has lost six of its last eight, while the Giants are 13-14 in the same span. The Diamondbacks’ bats have slipped to an 80 wRC+ since May 28, and they have scored the second-fewest runs in MLB over the past 30 days with 95. Their rotation has been even shakier: Ryne Nelson, Merrill Kelly and Zac Gallen have combined for minus-1.5 fWAR in 89 innings since the sweep, and their 7.08 ERA has pulled the staff backward. Soroka, who had four starts with a 2.57 ERA, a 3.10 FIP and plus-0.5 fWAR before going on the IL about 10 days ago, is part of that drop-off, but he has not been alone. Rodriguez has still flashed better results over his last five starts with a 2.20 ERA, even as the 4.81 FIP and 5.33 xERA undercut the surface work.
The Giants are not arriving empty-handed. They have scored 133 runs since May 28, good for 15th in MLB in that span, and their 126 wRC+ since then is far better than Arizona’s. Even so, they have still gone 13-14 over the past 30 days and have carried a 4.51 team ERA, which leaves enough room for the same problem to repeat if the pitching behind Logan Webb and Robbie Ray does not hold up. The break from the season series to the present has narrowed the overall form gap, but it has not erased the one fact that matters most in this matchup: San Francisco has yet to beat Arizona this year.
What comes next is simple and unforgiving. The Giants get another chance to change the record, and Arizona gets a chance to turn a commanding season hold into a sweep that will shape the rest of the division race.
