The San Francisco Giants keep running into the same wall, and on June 30 at Chase Field it happened again. Arizona handled them 8-2, with Landen Roupp’s start going south and the offense offering little outside of Luis Arraez’s hot bat.
That result was more than just another loss. It was the Giants’ eighth straight defeat against the Diamondbacks, a stretch that has turned Arizona into San Francisco’s most frustrating matchup of 2026. Every time these teams meet, the same pattern seems to show up: the Giants leave with another loss, and the Diamondbacks keep adding to a run that now stands as the most consecutive victories against an opponent to begin a season in franchise history.
Arizona’s success against San Francisco is also doing a lot of the heavy lifting in the standings. The Diamondbacks are 13-2 against the Giants and Rockies, while going 30-40 against everyone else. That split tells the story pretty plainly: Arizona has been piling up wins where it has been able to dominate.
The first meeting between these teams came on May 18 in Phoenix, and it set the tone fast. Arizona rolled to a 12-2 win in the opener, then followed it with a crushing comeback the next night. The Giants had a 3-1 lead in the ninth before Ketel Marte hammered a three-run walk-off homer to left field, and the Diamondbacks finished the sweep the next day with a 6-3 victory.
A week later, the scene shifted to San Francisco, but the result stayed the same. Merrill Kelly beat Roupp in the opener, Eduardo Rodriguez followed by outdueling Tyler Mahle, and Mike Soroka then took care of Tony Vitello’s squad. The scores - 6-2, 7-5 and 3-2 - added up to another sweep for Arizona.
The last two losses have come over the past couple of days. On June 29, the Giants were trying to close out the month after series wins over the Athletics and Atlanta Braves, but they came up short again in a 5-4 loss.
Rodriguez was excellent once more. Then came the June 30 defeat, the 8-2 game that only deepened the feeling that San Francisco has no answer for this opponent.
There are still five games left between the Giants and Diamondbacks this season. For San Francisco, the only hope now is that one of them finally breaks the pattern.

Giants Pitching Depth Concern Just Took Another Frustrating Turn
Wilkin Ramos is headed back to Triple-A Sacramento after clearing waivers, giving the Giants a way to keep the right-hander in the organization without using a major league roster spot. The move comes after his designation for assignment, and because he does not have enough service time to elect free agency, San Francisco can outright him and let him work to get back on track in the minors.
For a Giants club still trying to sort through pitching depth, the decision is another reminder of how quickly bullpen plans can change. Ramos was promoted to the big leagues in June for the first time, and the organization is now hoping the reset in Sacramento can help him regain form while keeping him available if the need arises again.

Giants Just Got A Tough New Reality On Hayden Birdsong
Hayden Birdsong is already back in the Giants orbit, even if the right-hander is still a long way from a mound. Recovering from Tommy John surgery performed March 25, he is rehabbing at the clubs minor-league facility in Scottsdale and remains limited in what he can do, but the work has resumed in earnest as he tries to move past the elbow injury that ended his 2024 season.
Birdsong is not scheduled to throw until September, with plyoball work expected to begin in the next two to three weeks, so this is still the slow part of the process. Even so, he has kept a positive mindset about what comes next, and for the Giants the larger reality is simple: any hope of getting him back in the near term has to be measured against a rehab timeline that will test patience all over again.

Giants Need Answers On Which Relievers Can Actually Be Trusted
The Giants have spent much of this season trying to patch together a bullpen that still looks far too familiar from a year ago. Injuries have pushed the front office to add a handful of pitchers, and a few minor trades have brought in fresh arms, but the overall picture has not changed much: there are still too many late-inning questions and not nearly enough reliable answers.
Dylan Smith has at least given them a competent look in a limited sample since coming over from the Tigers, and the search for usable depth continues to matter because the left side remains especially murky. Erik Miller may be the closest thing to a steady option there, but the Giants are still sorting through how much they can trust him, Matt Gage, and Sam Hentges, while Caleb Kilian and Keaton Winn look like the main names with a chance to fit into the longer-term solution. For a club that needs more than stopgaps, the next move may have to come from outside the obvious pool. [Read more 🡒]
