What happened: Arizona's season record against San Francisco stands at 7-0 entering Tuesday's matchup in Phoenix, with the most recent meeting decided 5-4. The Diamondbacks have taken every game the two clubs have played so far this year.
Why it matters: The mark is a rare bit of one-sided dominance: it is the first time San Francisco has dropped its first seven games against a single opponent since 2010. With the Giants sitting at 35-49 and Arizona at .500 (42-42), the lopsided head-to-head has been one of the few reliable bright spots in the Diamondbacks' season.
By the numbers: 2026 head-to-head (Arizona-San Francisco): June 29, ARI 5-4; May 27, ARI 3-2; May 26, ARI 7-5; May 25, ARI 6-2; May 19, ARI 12-2. Season records entering the day: Arizona 42-42 (4.2 runs scored, 4.6 allowed); San Francisco 35-49 (4.1 scored, 4.7 allowed). The Diamondbacks took the series opener despite being without Webb and Ray.
What to watch: The teams meet again Tuesday in Phoenix, where San Francisco looks to finally break through against an opponent it has yet to solve in 2026.
