Rockies right-hander Antonio Senzatela and the D-backs Merrill Kelly are both looking to snap out of a funk. They have both lost three of their last four starts. Senzatela is coming off his least productive start in his career, allowing eight runs in 3 1/3 innings at Pittsburgh last Thursday. Kelly only lasted 1 2/3 innings in his last start, allowing four runs, at San Diego last Wednesday. Senzatela is 1-3 against the D-backs, winning his last start, Sept. 22 last season, when he gave up one run on three hits in seven innings. Kelly has never faced the Rockies.

Senzatela has had his challenges from Nick Ahmed, who is 4-for-10 against him lifetime. David Peralta, who has only one hit in 12 career at-bats, is on the injured list. The rest of the D-backs roster has only five hits in 29 at-bats against Senzatela. Kelly has never faced anyone on the Rockies roster at the big-league level.
