Both the Arizona Diamondbacks and the San Francisco Giants will enter the opener of this three-game series coming off a rest day. Note that the Diamondbacks are a perfect 5-0 in their last five games following an off day while the Giants are 3-7 in their last 10 games in the same situation.

Arizona right-hander Merrill Kelly (3-4, 4.70 ERA) has compiled a respectable 3.20 ERA through 25 1/3 innings of work home at Chase Field on the season. His last outing was decent with three runs allowed and five Ks through seven innings of work.

The Giants turn to Jeff Samardzija (2-1, 3.51 ERA) who was tagged with three runs on five hits and three walks over just four innings against the Reds last time out. He has posted a 4.43 in four road starts on the season and the Giants are 5-18 in the veteran right-hander's last 23 road starts vs. a team with a winning record.

Arizona is one of the top hitting teams in the National League (.260 AVG, 64 home runs) and I think the D'Backs will put enough runs on the board to get the win here.

8* play on Arizona Diamondbacks.
