San Francisco @ Arizona preview

Last Meeting ( Aug 2, 2018 ) San Francisco 8, Arizona 1

The San Francisco Giants look to post their fifth straight victory and further tighten things up in the National League West when they host the Arizona Diamondbacks for the second contest of their four-game set. The Giants trounced Arizona 8-1 in the series opener and are five games behind the division-leading Los Angeles Dodgers with two teams between them.

Austin Slater went 2-for-3 with two RBIs and three runs scored for San Francisco, which is 3-0 on its six-game road trip. The Diamondbacks dropped to 1-2 on their nine-game homestand with Thursday's setback and fell one game behind Los Angeles while remaining one in front of Colorado. David Peralta recorded four hits while Eduardo Escobar drove in the lone run for Arizona, which is one-half game out of a wild-card spot. Escobar has gone 5-for-16 with three RBIs in four contests since being acquired from Minnesota.
