The Arizona Diamondbacks hold a perfect 7-0 record against the San Francisco Giants during the 2026 season. The Diamondbacks secured their latest victory in the series on Monday, defeating the Giants 5-4 in Phoenix to extend their season-long winning streak against the franchise.

How the Diamondbacks Secured the Victory

The Giants staged a late rally against Diamondbacks closer Paul Sewald. Heliot Ramos initiated the comeback with a solo home run, followed by a Bryce Eldridge single and a run-scoring hit from Drew Cavanaugh. Despite the pressure, Sewald retired Drew Gilbert and Matt Chapman to secure his 19th save in 20 opportunities.
