San Francisco Giants vs. Arizona Diamondbacks Against the Spread

The Giants have been struggling recently, posting only four wins over their past six games and three on the road in those 10 contests (going 1-9 straight-up in all 10). Yet one bright spot may lie within Arizona: They managed five victories out of seven against them while suffering significant road defeats (3-7 straight up record in their last 10 road contests against Arizona; an indication of just how difficult an opponent they present themselves against), particularly at Chase Field where Diamondbacks have thrived lately.

The Diamondbacks have been riding on the crest of a wave with an 8-4 record in their last 12 games and an impressive 5-1 at home in their last 6 games. The team has a strong record playing at home against San Francisco, with a 7-3 straight-up record in their last 10 games. Their performance trends suggest they’re in a good position to cover the spread, especially given their recent home success and ability to keep the Giants at bay when playing in Arizona.
